BIM Specialist: Room and Schedule Productivity Toolkit

Overview

BIM Specialist is a productivity toolkit for Autodesk Revit. It puts room-management and schedule workflows on one dedicated Revit ribbon tab, with the aim of cutting repetitive manual steps for architects, engineers, BIM coordinators, and model authors. The Autodesk Marketplace listing describes four focused tools: 3D Rooms, Room Info, Schedule Export, and Import History. Two of them, Room Info and Schedule Export, are free. The other two are paid features, with a 30-day trial of everything and a monthly subscription afterward. The vendor's website describes the product as being organized around three workflow areas: room workflows, schedule workflows, and model management.

Note on sources: "BIM Specialist" is a generic name, and several other Revit tools use similar names. This summary covers the add-in published on the Autodesk Marketplace under the publisher name "BIM Specialist," with its own website at bimspecialist.github.io. It is based on the Marketplace listing and publisher profile, the vendor's website, and the vendor's GitHub repository. I found no independent reviews or hands-on tests. Everything below describes what the vendor says the tools do.

Key Facts

• Publisher: BIM Specialist, which describes itself as developing productivity and BIM automation tools for Revit. It also offers custom Revit add-in development, workflow automation, schedule and parameter tools, and model coordination utilities.
• Type: A desktop Revit add-in installed from the Autodesk Marketplace. The installer includes the components for each supported Revit release and creates the ribbon tab automatically.
• Ribbon: A dedicated BIM Specialist tab.
• Price: Two tools are free. Full access is USD 4.99 per month for one user, after a 30-day trial of all tools.
• Licensing: Linked to the Autodesk account signed into Revit, so no separate BIM Specialist account is needed. The add-in contacts the vendor's licensing service to verify entitlement and can work offline for a time through a license cache.
• Support: A support page on the vendor's website. The website has a bilingual English and Arabic interface and a documentation page.

The Four Tools

3D Rooms (paid)

Creates and updates three-dimensional room volumes from the native room data in the Revit model. This lets you review spatial information visually in 3D and apply consistent styles to the volumes. Revit rooms are normally shown in plan, so a 3D volume is useful for reviews, presentations, and checking how spaces relate to each other. The listing doesn't say which element category the volumes use or how they stay in sync when rooms change, so check how they behave before putting them in schedules or views.

Cable Modeling: Cables over Containment

Overview

Cable Modeling is a Revit add-in from ABM_Engineer, the Autodesk App Store publisher name of electrical BIM developer Abdelrahman Mobarak. It creates cables over existing cable trays, from the host model or a linked model, as Revit conduit elements with the parameters needed to schedule them. Its purpose is accurate cable quantities on large projects. The developer says contractors usually build these cables by hand with sections and 3D views, which is slow on complex designs. The add-in supports Metric and Imperial standards and has a cable bill of quantities (BOQ) tool and Excel import and export.

Note on sources: This summary is based on the Autodesk App Store listing and its FAQ, the ABM_Engineer publisher profile, the developer's LinkedIn posts, his two YouTube demonstrations, and a third-party directory page. I found no independent reviews or hands-on tests. Descriptions of what the tool does come from the developer.

Key Facts

• Developer: ABM_Engineer, whose publisher profile and LinkedIn posts point to Abdelrahman Mobarak, a BIM developer and electrical BIM design engineer. The publisher says it develops automated plugins, mainly electrical tools.
• Standards: Metric and Imperial units.
• Input: Existing cable trays in the host model or a linked model.
• Output: Cables modeled as conduits with required parameters, plus cable tagging data and a cable BOQ.

What It Does

• Cables as conduits: Revit has no native cable element to run along a tray, so the add-in models each cable as a conduit. Conduits can be scheduled and measured with Revit's normal tools, which gives usable lengths and counts.
• Cable layout controls: You set the number of cables, the number of vertical layers, the spacing, the cable diameter, the tray inset, and more. It supports flat and trefoil formations.
• Cable sizes and colors: You choose a cable size instead of typing a diameter, and you can set up custom sizes with your own names. Cables can be colored.
• Host and linked trays: Cables can be created over cable trays in the host model or in a linked model.
• Routing option: A containment selection option detects the shortest routing for a load. The FAQ says the load must be connected to an electrical panel for this to work.
• Length summary: After the cables are created, a message gives the total length of the conduits (cables) just made.
• Cables BOQ: A button opens a cable bill of quantities. You enter fed-from, fed-to, and cable details for each cable in a table. Double-clicking a cable run opens an isolated 3D view of it. The developer says this streamlines quantity take-offs.
• Excel import and export: Cable descriptions can be imported or exported through Excel. The FAQ says conduit sizes can be exported to Excel too.

Free BIMK.XPorter: Multi-Format Export Manager

Overview

BIMK.XPorter is a free Revit add-in from BIMK-TOOLS that gives BIM users a single workspace for preparing and running exports. Instead of repeating export steps across several Revit dialogs, you pick the sheets and views you need, switch on the output formats, preview the file names, check the destination folder, and watch the export's readiness and progress. The Autodesk App Store listing calls it a "professional multi-format export manager" and says it helps users run export workflows "in a clearer and more controlled way." It's aimed at BIM production teams, coordinators, engineers, modelers, and documentation users, and it's the first application from BIMK-TOOLS, a developer working on further Revit tools.

Note on sources: This summary is based on the Autodesk App Store listing, the BIMK-TOOLS publisher profile, and two LinkedIn posts by the developer, one with a feature walkthrough. I found no independent reviews or hands-on tests.

Key Facts

• Developer: BIMK-TOOLS is the publisher on the Autodesk App Store. The add-in is announced on LinkedIn by Khaled ElSagheer, who says he built it as his graduation project for an Application Development diploma, using C#, WPF, and the Autodesk Revit API. The support address on the listing matches his name, but no page I found states outright that BIMK-TOOLS is his own publisher account.
• Where it runs: Locally inside Revit, with no cloud services or user account.

Room 2 Model: Finishes from Revit Rooms

Overview

Room 2 Model (also written Room2Model) is a Revit add-in from PROISAC-BIM-VDC that creates finishes directly from the Rooms already in a project. Instead of drawing each floor finish, wall finish, or ceiling by hand, you select Rooms in a floor plan view and the add-in builds the finish elements from the room shapes and room data. The Autodesk App Store listing describes it as a way to create finishes "in seconds, as easy as selecting and clicking." An optional setting uses the doors in each room to extend the floor finishes so they line up with the doors, which gives a cleaner result.

Note on sources: This summary is based on the Autodesk App Store listing, PROISAC's own store page, PROISAC's publisher profiles, and a third-party directory page. I found no independent reviews or hands-on tests. The Autodesk listing shows one 5-star rating, and the directory page reads like a generated write-up of the listing, so I treated it as a copy of the vendor's description, not as a review. The listings give only brief descriptions, so detail on settings and behavior is limited.

Key Facts

• Developer: PROISAC-BIM-VDC (Prometheus Ingenieros SAC), a BIM and VDC company that develops add-ins for Revit, Navisworks, and AutoCAD. It says it was the first Latin American company to publish BIM apps on the Autodesk App Store.
• What it creates: Floor finishes, wall finishes, and ceilings from room shapes or room data. PROISAC's store page also mentions skirting (base) pieces.
• How you use it: From a floor plan view, select Rooms as references, and the finishes are generated with the same shapes as the rooms.
• Door option: Floor finishes can be extended to line up with the room's doors.
• Licensing: Time-limited subscription licenses, not a perpetual license. See Pricing and Licensing.

Free Ze’Connect: Batch Export, Link Management, and Scheduling

Overview

Ze’Connect is a Revit add-in from ZestineTech that automates some of the most repetitive coordination chores: exporting models for review, keeping links pointing at the right files, and moving models to the cloud. Its main idea is to stop opening files one by one. Pick a set of Revit models, local or in Autodesk Forma or BIM 360 projects, and Ze’Connect processes them in the background without opening each model in the Revit window. ZestineTech's product page lists five tools in one add-in: Batch NWC Export, Batch DWG/PDF Export, Batch IFC Export, Link Remapper, and Cloud Collaborate. A later update added Scheduled Export, which runs the exports automatically, even when Revit is closed, and Auto Open Revit, which opens a chosen model at a set time. ZestineTech describes it as a flagship product.

Note on sources: This summary is based on ZestineTech's product page and its "how it works" page, the Autodesk App Store listing, ZestineTech's two YouTube tutorials, and a third-party directory entry. Autodesk's documentation provides background on cloud models and supported Revit versions. I found no independent reviews or hands-on tests, so time-saving claims, such as the product page's "half the overhead," come from ZestineTech.

The Problem It Addresses

ZestineTech frames the problem around "the 8 AM problem," the routine that starts every coordination review. It names three pain points:

• Repetitive exports: Open a model, pull the 3D view, export the NWC, save, close, and repeat across dozens of models. Hours disappear before coordination even begins.
• Broken connections: A server rename or a BIM 360 migration breaks links. Each one has to be inspected, remapped, and reloaded in Revit's Manage Links dialog, one link and one model at a time.
• A hidden productivity tax: One missed view or outdated export can compromise a whole coordination review. Small manual tasks become a recurring cost on every project.

Free Ze’Diag: Revit Journal Analyzer

Overview

Ze’Diag is a free diagnostic tool from ZestineTech that explains why Revit crashed or misbehaved. Revit records every action, add-in call, and error in a session in a plain-text journal file. These files run to thousands of lines and are hard to read by hand. With Ze’Diag, you upload a journal and get back a structured, readable report. The report covers whether Revit crashed, the likely root cause, the errors and warnings raised, links that failed to load, where time was lost, and which add-ins may have been involved. It also links to known Autodesk solutions where they apply. The report can be downloaded as a PDF to share with the team. ZestineTech's pitch is to diagnose crashes "in minutes, not hours."

Note on sources and scope: Ze’Diag isn’t installed inside Revit. It’s a web application you open in a browser, and it’s listed on the Autodesk App Store as a "web-based Autodesk Revit journal analyzer." Some directories group it under Revit add-ins and scripts because it’s part of the Revit tool ecosystem. This summary is based on ZestineTech’s product page, the Ze’Diag web app’s own pages, the Autodesk App Store listing, ZestineTech’s LinkedIn posts, a third-party directory entry, and Autodesk’s documentation on journal files. I found no independent reviews or hands-on tests. Performance claims, such as the speed of the analysis and the crash statistics on the product page, come from ZestineTech.

The Problem It Addresses: Reading Revit Journals

Autodesk's documentation explains what journals are and why they matter, and it shows why a tool like Ze’Diag has a place:

• Revit writes a journal every session: A new journal file (for example Journal.0001.txt) is created each time Revit starts, and the highest number is the most recent. Journals record activity from startup to shutdown. They're normally stored under the user's local AppData folder, in Autodesk\Revit\Autodesk Revit [version]\Journals, which is hidden by default in Windows.
• They hold the answers but are hard to read: Autodesk describes journals as useful for troubleshooting both on the affected machine and remotely. Reading them takes practice, because you have to know what to search for, such as exceptions, fatal errors, add-in entries, and the last successful command before a failure. ZestineTech notes that most BIM users aren't trained to do this.
• Other files travel with them: The journals folder can also hold dump files (.dmp) created when the program crashes, plus worker logs and abbreviated journals. Autodesk tells users to send a dump file to Product Support along with the journal.
• Crash investigations are manual: Common practice is to open the journal in a text editor, search for keywords, find the last successful command and the first error, and isolate suspect add-ins. Autodesk also offers a Notepad++-based search method for documented issues.

Ze’Diag automates that first-pass reading and presents the result in a consistent report format.

BIMIT by Integrated Projects (IPX): Scan-to-BIM as a Service

Overview

BIMIT is Integrated Projects' (IPX) scan-to-BIM product. You upload a registered point cloud of a building, and BIMIT turns it into a Revit model, floor plans, CAD drawings, and a quality report. It's sold as a standardized product with published prices, not as a custom modeling engagement. IPX launched BIMIT 4.0, a new engine, on October 15, 2026. It offers three settings. BIMIT 100 and 200 are fully automated, and BIMIT 300 adds an architect's review. IPX says its starting price is 4¢ per square foot for fully automated models, delivered in hours.

Note on sources and scope: BIMIT is an online ordering and delivery service, and what you get back is a Revit model (.rvt) that you open in Revit as normal. This summary is based on IPX's own BIMIT pages, its help center, developer documentation, and launch posts. I found no independent reviews or hands-on tests, so the speed, cost, and accuracy figures below are IPX's own claims.

What BIMIT Is, and Isn't

IPX's help center describes BIMIT as a fixed-price product that turns a point cloud into a usable building model, built to confirm square footage and equipment counts quickly. IPX is explicit about what it is and isn't:

• It is: A product with standardized, predictable pricing. It's built for fast, on-time delivery and can combine architecture, furniture, and MEP in one model file. It's intended for verifying floor areas, room dimensions, and element counts.
• It isn't: A custom service with a unique quote for every job, work priced by the hour or as a lump sum, or a set of separate files from different consultants.
• Not construction-grade: IPX says BIMIT should not be used as a definitive guide for construction. Point cloud registration from devices such as the Matterport Pro2 or Leica BLK360 has accuracy limits. Licensed professionals should always field-verify.
• No materials or specifications: The model has geometry but no material information or construction details. Non-graphical data is kept generic, so you can customize it yourself.

Product Roundup: underbim (ub.Suite Edition 1)

Overview

underbim was created around one idea: BIM technology should make real work easier. It is a focused, independent company built on about 25 years of hands-on BIM and Revit experience, starting in October 2001. It took shape as underbim around a decade ago, when practice, consultancy, and development came together under one identity. Its current product line, ub.Suite, turns real workflows into focused Revit software.

Key Takeaways

• Practice first: underbim did not start as a software company looking for problems to solve. It grew out of years of work with BIM models, project teams, training, and real production constraints.
• Workflow before software: The approach is to observe the real problem, structure the workflow, and then build a focused tool around it. Anything Revit already does well natively is kept, and unnecessary steps are removed.
• One person across the whole chain: The founder identifies workflow problems, analyzes them, designs the solution, writes the software, and understands how it behaves in a real BIM environment.
• Focused, ownable products: ub.Suite is a collection of focused tools that extend Revit where everyday workflows can be made clearer, faster, and more effective. It is licensed perpetually, with no subscription required to keep using the Edition purchased.

From BIM Practice to Software

Over the years, underbim has worked across BIM consultancy, implementation, training, automation, and custom development. Its process has three steps:

1. Observe: Find the real problem by looking at the work itself, including recurring friction, repetitive operations, information gaps, and model-control needs.
2. Structure: Reduce the problem to a clear sequence of steps, preserve what already works natively in Revit, and remove unnecessary steps.
3. Build: Develop focused software around the workflow instead of forcing the workflow around the software.

BackupMover: Keeping Revit Backups Out of the Working Folder

Overview

ub.BackupMover is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy that has worked in BIM, Revit training, consulting, and software development since 2001. It is one of eight independent add-ins in ub.Suite Edition 1, which launched in late October 2026, and is positioned as a file safety utility. Its tagline, "Move the backups. Keep the folder clear," sums up the approach. It finds genuine Revit project and family backup files beside the current document and moves them into a controlled subfolder, keeping the working folder readable. It can run manually or automatically after each Save.

Note on sources: This summary is based mainly on underbim's full BackupMover product page, which covers the workflow, feature explorer, detection rules, manual and automatic modes, destination handling, and licensing. Background on how Revit creates backups comes from Autodesk documentation, Autodesk forums, and Revit community blogs. An independent review or hands-on test was not found, and gaps are listed under Open Questions.

The Problem Area: Revit Backup Files

Revit creates backup files automatically whenever a model is saved or synchronized. Where they go and how they behave depends on the type of model, and the sources below describe several recurring problems:

• Backups are saved beside the model, with no setting to change it: For standalone (non-workshared) models, Revit places backups in the same folder as the project, named like "project name.0001.rvt," "project name.0002.rvt," and so on. Forum answers confirm there's no built-in way to choose a different location. Once the maximum backup count is reached, Revit overwrites the oldest backup.
• Folders fill up with clutter: The numbered backup files pile up next to the files people actually work with, and they're easy to mistake for real project files. Revit family files create the same kind of backups.
• Cloud sync and server replication get overloaded: Users report that OneDrive uploads every backup, which wastes bandwidth and data. An IT manager described tens of gigabytes of extra data slowing synchronization between four offices.
• Workshared models use a separate backup folder: Revit stores central and local model backup information in a folder named [model name]_backup next to the model. Autodesk says not to delete or rename files in it, and to keep the folder with the model if it's moved or copied, renaming it to match if the model is renamed. Backups in this folder are incremental, so they aren't ordinary .rvt files.
• Manual and scripted workarounds: Common approaches include deleting backup files by hand, batch files with wildcards, Dynamo or Python scripts that move or delete files matching the numbered pattern, and older add-ins such as MoveBackup (later Wormhole for Revit), which moved backups into a subfolder or a chosen directory.

BackupMover addresses the clutter problem for standalone project and family files. Like the older add-ins, it moves numbered backups out of the working folder. Unlike broad scripts, it works only from the active document and applies strict matching rules, so it only ever moves files that are clearly that document's own backups.

Elevations: Top and Bottom Elevation Data for Revit Elements

Overview

ub.Elevations is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy that has worked in BIM, Revit training, consulting, and software development since 2001. It is one of eight independent add-ins in ub.Suite Edition 1, which launched in late October 2026. Despite its name, it doesn't create elevation views. It's a vertical data tool. Its tagline, "Know where every element starts and ends," sums up the approach. It calculates each element's upper and lower elevations from its extents in the Revit model and writes them to usable instance parameters, using either Project or Survey coordinates as the reference.

Note on sources: This summary is based mainly on underbim's full Elevations product page, which covers the workflow, feature explorer, coordinate references, parameter output, and licensing. Background on Revit's elevation parameters and coordinate system comes from Autodesk documentation and community forums. An independent review or hands-on test wasn't found.

The Problem Area: Vertical Data in Revit

Knowing the absolute top and bottom elevation of elements matters for coordination, clearance checks, scheduling, tagging, and handing data to contractors or other software. Revit shows this information graphically, but it isn't consistently available as data that can be scheduled. Autodesk documentation and user forums describe several gaps:

• Built-in elevation parameters only exist for some categories: Ducts, pipes, cable trays, and conduit have detailed top, bottom, and centerline elevation parameters, and structural framing has Elevation at Top and Elevation at Bottom. Many other categories have no equivalent absolute elevation values.
• Level-relative values, not absolute ones: Parameters such as Elevation from Level give an offset from a level, not an absolute height. They're also unavailable in multi-category schedules.
• No level elevation in schedules: For elements such as columns, a schedule can show the base and top level names and offsets, but not the level's elevation as a number. That means you can't calculate the actual top or bottom elevation in a schedule or tag. This is a long-standing request on the Revit Ideas board.
• Annotation isn't data: Spot elevations can show heights relative to the Project Base Point or the Survey Point, but they're annotations in a view, not parameter values you can filter, schedule, or export.
• Dynamo workarounds go stale: A common fix is to add shared parameters and fill them with a Dynamo script. Forum users point out that values become outdated as heights and offsets change, unless someone remembers to rerun the script.
• Coordinate references cause confusion: Revit has an Internal Origin, a Project Base Point (the project's local zero), and a Survey Point (the real-world reference, often sea level). The same element can have very different elevation values depending on which reference is used.

Elevations addresses this gap. It works the same way across whichever categories you choose: it calculates top and bottom values and writes them to parameters you control, with the coordinate reference stated explicitly.

ScopeViews: Scope Box–Driven View Creation for Revit

Overview

ScopeViews is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy that has worked in BIM, Revit training, consulting, and software development since 2001. It is one of eight independent add-ins in ub.Suite Edition 1, which launched in late October 2026, and is positioned as a view creation tool. Its tagline, "Define the scope. Generate the views," sums up the approach. It turns selected Revit Scope Boxes into repeatable sets of plan, section, and 3D views. View templates, scale, and naming are all set before the views are created.

Note on sources: This summary is based mainly on underbim's full ScopeViews product page, which covers the workflow, feature explorer, generated view set, templates and scale, naming, and licensing. The background on scope boxes comes from Autodesk documentation and community forums. An independent review or hands-on test was not found, and the gaps are listed under Open Questions.

The Problem Area: Views and Scope in Revit

In Revit, view "scope" is mainly controlled by scope boxes and crop regions. A scope box is a 3D region drawn around part of the model. Assign it to views and their crop extents follow the box, so changing the box once updates every view that uses it. Assign it to grids, levels, and reference planes and they appear only in views whose cut plane intersects the box. The difference is often summed up as "a crop region belongs to one view, a scope box belongs to the project." Documentation and user forums point to several recurring pain points:

• Repetitive view setup: Large or multi-zone projects need many plans, ceiling plans, and dependent views cropped consistently. Cropping views by hand often leaves them slightly misaligned on sheets.
• Assignment limits: Scope boxes can only be created in plan views. Since Revit 2023, users report they can no longer assign or change scope boxes on dependent section views and some other dependent views, though dependent floor plans still work.
• Finding and tracking scope boxes: Scope boxes appear only in views they intersect. Forum users report "losing" a scope box after deleting the views where it was visible, and they have no easy way to see which views use which box.
• Greyed-out or conflicting settings: The Scope Box parameter can be unavailable, for example when a view template controls it, which makes troubleshooting harder.
• Bulk work needs add-ins: Creating dependent views from scope boxes, reassigning scope boxes across many views, or copying scope boxes from linked models is commonly done with third-party add-ins or Dynamo, not native tools.

ScopeViews tackles the repetitive-setup part of this problem. It uses the Scope Boxes you've already defined as the spatial basis for generating complete, consistently set-up view sets, so you don't have to create and crop each view by hand.

ConstraintScanner: Inspecting Constraints in Revit Projects

Overview

ub.ConstraintScanner is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy that has worked in BIM, Revit training, consulting, and software development since 2001. It is one of eight independent add-ins in ub.Suite Edition 1, which launched in late October 2026, and is positioned as a model diagnosis tool. Its tagline, "See the relationships. Inspect what they mean," sums up the approach. It scans Revit constraints, dependencies, and model conditions, narrows the results to the relationships that matter, and lets users go straight from the evidence to the elements involved, without changing the model.

Note on sources: This summary is based mainly on underbim's full ConstraintScanner product page, which covers the workflow, feature explorer, coverage, and licensing. The background on Revit constraints comes from Autodesk documentation and community forums. An independent review or hands-on test wasn't found, and gaps are listed under Open Questions.

The Problem It Addresses: Constraints in Revit

Constraints build intelligence into a Revit model by setting relationships between elements. They're powerful, but they're also a common source of confusion and unexpected model behavior. Autodesk's documentation and user forums describe several traits that make constraints hard to manage at project scale:

• Several kinds of constraints: Explicit constraints (locked alignments, locked dimensions, and EQ equality constraints) always hold, and conflicts with them cause errors. Looser relationships, such as unlocked dimensions and alignments, may be dropped without notice when a conflict occurs. Implied constraints, such as walls attached to roofs or joined at corners, are managed by Revit itself.
• Constraints exist apart from dimensions: Constraints don't belong to a specific view and can exist without the dimension that created them. Deleting a dimension doesn't always remove the constraint, so "hidden" constraints can remain in the model. Several locked dimensions between the same two references can also map to a single constraint.
• Hard to trace: Revit's native Reveal Constraints mode shows constraints only temporarily, in the current view. Users on Autodesk forums report they can't find which locked dimension or view controls an element, or "take me to" the source of a constraint.
• No native bulk review: Revit has no built-in way to list, filter, or unlock constraints across a whole project. Users have turned to Dynamo scripts or the Revit API, where constraints sit in a separate category from dimensions.
• Over-constraining and unpredictable behavior: Leftover or unnecessary locks can make elements resist edits or move unexpectedly. In workshared models, a constraint can't be edited if any constrained element is in a workset the user can't edit.

ConstraintScanner is aimed at this gap. It helps BIM managers, coordinators, and modelers inspect and understand the constraints and dependencies already in a model, instead of discovering them one at a time when an element won't move.

ProjectManager: Project Cleanup with Context Attached

Overview

ProjectManager is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy with experience in BIM, Revit training, consulting, and software development since 2001. It is one of eight add-ins in ub.Suite Edition 1, released in late October 2026, and can be purchased individually or as part of the suite. underbim summarizes its purpose as “Know what is in the project. Decide what stays.” The add-in audits recurring Revit project resources—V/G filters, scope boxes, view templates, and views—classifies them as used, unused, or unreferenced, shows their dependencies, and supports batch view management and controlled cleanup. Its defining principle is “audit first, change second”: discovery and filtering are kept separate from destructive operations, every change can be previewed before it is applied, and an applied operation retains a single Revit Undo path.

This summary is based primarily on the text of the official ProjectManager product page, supplemented by underbim’s website, suite overview, and announcement. The product page is marketing material: the Views workflow and delete behavior are described in detail, while some feature areas are summarized briefly. No user guide, independent review, or hands-on testing was available, so the remaining gaps are listed as open questions rather than filled with assumptions.

Core Concept: Audit First, Change Second

ProjectManager brings recurring project-management operations into one place, so the target set can be understood before anything is renamed, detached, or deleted. The product page frames this in four stages:

• Find: search, filters, and project content.
• Classify: used, unused, and unreferenced.
• Review: dependencies, protection, and preview.
• Act: batch changes, delete, and Undo.

Six-Step Workflow

underbim describes the workflow as “Find the target set. Understand it before acting.” Discovery and filtering are separated from destructive operations so that project cleanup remains an explicit user decision:

1. Audit: read the current project content across the supported resource areas and views.
2. Filter: reduce the list by usage, search criteria, or native Revit view properties.
3. Understand: review usage counts, dependencies, sheet placement, references, and protected conditions.
4. Select: build the working set manually or from the current filtered result.
5. Preview: see what will be deleted, skipped, or detached before the Revit document is modified.
6. Apply: commit the selected operation, review the result, and retain a single Revit Undo path.

InterferenceInvestigator: Interference Management in Revit

Overview

InterferenceInvestigator is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy with experience in BIM, Revit training, consulting, and software development since 2001. It is one of eight add-ins in ub.Suite Edition 1, released in late October 2026, and can be purchased individually or as part of the suite. underbim summarizes its purpose as “See the clash. Understand the pair.” The add-in focuses on the work after interference detection: moving from an interference result to the exact host and linked elements involved, locating them in the Revit model, recovering enough surrounding context to understand the problem, tracking a review state for each occurrence, and turning the investigation into an actionable result. Reviewed results can become a native Revit schedule, a .ubr result package, or input to ModelData.

This summary is based primarily on the text of the official InterferenceInvestigator product page, supplemented by the ModelData and FilterToSchedule product pages, underbim’s website and suite announcement, and Autodesk documentation on the native Interference Check. The product page is marketing material: several feature areas are described in detail, while others are only named. No user guide, independent review, or hands-on testing was available, so the remaining gaps are listed as open questions rather than filled with assumptions.

Core Concept: A Clash Becomes Useful When You Can Investigate It

underbim states that InterferenceInvestigator is “built for the work after detection”: identifying the pair, reaching the actual elements, understanding their model context, and deciding what needs to happen next. The product page frames this as four stages:

• Result: a structured interference set.
• Pair: host and linked participants with their identities.
• Context: select, isolate, and Focus 5%.
• Continue: schedule, .ubr, or ModelData.

The page’s coordination-workflow graphic illustrates a pair consisting of a host structural beam and a linked service element, labeled “Status · Open,” following a path of pair → model → context.

ModelData: A Schedule-Centered Data Workbench

Overview

ModelData is an Autodesk Revit add-in from underbim, a Portugal-based BIM consultancy with experience in BIM, Revit training, consulting, and software development since 2001. It is one of eight add-ins in ub.Suite Edition 1, released in late October 2026. underbim positions it as a “data workbench” to “build, inspect, calculate and refine Revit schedule and model data with more control over the logic behind the result.” Rather than replacing Revit schedules with a separate data viewer, ModelData extends the schedule workflow with richer field sources, logical filters, grouping, calculated and combined values, investigation in the model, and reusable definitions and results. It is sold individually or as part of the complete ub.Suite.

This summary is based primarily on the text of the official ModelData product page, supplemented by underbim’s website and suite announcement. The product page is marketing material: it describes capabilities at a high level, and some feature areas are named without detailed explanation. No user guide content, independent review, or hands-on testing was available, so those gaps are identified in the open-questions section rather than filled with assumptions.

Core Concept: Work with the Logic Behind the Schedule

The product idea is to extend Revit’s schedule workflow “with filters, grouping, derived values and model context — while keeping the native Revit schedule at the centre.” underbim frames this as four connected layers:

• Input: native and semantic fields.
• Logic: filters and structure.
• Data: calculated and combined values.
• Context: investigation in the model.

The product page includes an illustrative data-workbench preview listing walls with Element, Level, Calculated, and Status columns, in which one row is flagged “CHECK” while the others show “OK.” This suggests that calculated values and status-style results can be used to flag items for review. Because it is a marketing preview, the specific rules behind such a status column are not explained.

Six-Step Workflow

underbim describes a connected workflow in which each step, “from source data to final output,” remains part of the same process:

1. Fields: choose native, semantic, and derived data sources.
2. Filter: build conditions and logical groups around the result.
3. Structure: sort, group, and organize the schedule output.
4. Calculate: create concatenations and calculated data where needed.
5. Investigate: move from rows and values back into model context.
6. Output: keep the Revit schedule or continue into reusable results.
