SWAPP.AI: An Operational Intelligence Layer for Architecture

Executive Overview

SWAPP.AI is an enterprise architecture-production platform that applies firm-specific artificial intelligence directly inside Autodesk Revit and Graphisoft Archicad. Its Revit experience is centered on an agentic assistant called Frank, which can read and write the live BIM model rather than merely answer questions or generate instructions. SWAPP positions the system as an operational intelligence layer: it executes documentation, modeling, annotation, coordination, and quality-control work using the firm's established standards and prior production decisions.

The platform's principal value is large-scale construction-document automation. Published capabilities include creating and organizing views and sheets, placing dimensions, tags, and callouts, generating schedules, modeling walls, doors, fixtures, finishes, and worksets, detecting collisions and annotation conflicts, checking accessibility conditions, and validating a model or drawing set against firm rules. SWAPP states that its automation can address up to 80% of repetitive documentation tasks, although actual scope and savings vary by project, onboarding, and encoded standards.

SWAPP is not a conventional self-service Autodesk Marketplace utility with a fixed command list. Deployment begins with a vendor-led onboarding engagement, the workflows are configured to the architecture firm's methods, and commercial access is sold through custom, credit-based pricing. The most accurate description is therefore a managed AI production system integrated with Revit, with human approval and auditability built into its execution model.

Frank: The AI Architect Inside Revit

Live-Model Execution

Frank operates in the active Revit environment and is described as reading and modifying the live model without creating a disconnected export or copy. Users can trigger work conversationally or launch configured skills and scripts. Frank proposes an operation, the user reviews or previews it, and execution occurs only after approval. This human-in-the-loop pattern is important because the system is acting on liability-bearing project data rather than producing advisory text.

Published Revit Capabilities

• Agentic modeling: Creates or adjusts walls, doors, fixtures, finishes, and worksets, including building-scale 2D-to-3D workflows.
• Dimensions and annotations: Places exterior and interior dimension strings, tags, room tags, callouts, and other annotations according to firm rules.
• Views and sheets: Generates views, establishes sheets, and organizes documentation sets.
• Model and set QA: Checks content against encoded standards, flags discrepancies, and can propose corrections.
• Collision and graphic cleanup: Detects model conflicts and overlapping annotations, then resolves approved issues in Revit.
• Accessibility review: Identifies certain ADA-related conditions and proposes model changes.
• Reusable automation: Prompts and successful procedures can be saved as repeatable skills or scripts, turning one-off instructions into standardized firm tools.
• Traceability: SWAPP states that actions are reversible and recorded in an audit trail.

Skema: A Web-Based Generative-Design and BIM-Automation Platform

Executive Overview

Skema is a web-based generative-design and BIM-automation platform for architecture and AEC teams. Its Revit add-in is the interoperability layer that connects a firm’s existing BIM knowledge to Skema and returns developed designs to Revit. The workflow is unusual among generative tools because it begins with proven Revit content—such as repeatable units, assemblies, families, parameters, and office standards—rather than producing disconnected conceptual geometry that must later be rebuilt.

Through the add-in, teams organize Revit model groups as reusable catalog units, validate and upload them to a cloud Design Catalog, update or remove catalog content, and synchronize Skema-generated layouts back into Revit as native BIM. The broader Skema application then lets designers compose and morph those units within new footprints, compare alternatives using live project metrics, and progress from early feasibility toward a detailed model.

The key distinction is that Skema is not simply a ribbon utility running entirely inside Revit. The add-in handles catalog creation and BIM exchange; option generation, catalog configuration, and metric-driven design occur primarily in Skema’s cloud workspace.

Primary Roles of the Revit Add-in

1. Create and Maintain Design Catalogs

The catalog side of the add-in converts selected Revit model groups into reusable design units. A unit may represent an apartment, hotel room, patient room, classroom module, office neighborhood, building core, façade bay, or another repeatable assembly. The upload preserves the BIM information associated with the group so the component can be stretched, morphed, arranged, and later reconstructed as Revit content.

2. Validate Revit Content Before Upload

The plug-in identifies units, compares them with the cloud catalog, and reports validation or synchronization status. Teams can add new units, remove obsolete ones, or re-upload only units that have changed. Unchanged catalog content remains intact, reducing unnecessary replacement.

3. Synchronize Skema Designs into Revit

After a design is developed in the web application, the add-in translates the layout into a Revit project. Published material describes native walls, floors, roofs, families, rooms, parameters, materials, and other BIM components rather than a flattened or reference-only import. The objective is to continue development and documentation without remodeling the concept from scratch.

ELLAH-M: A Structural-Production Toolkit

Executive Overview

ELLAH-M is a Revit productivity add-in developed specifically for structural engineers and BIM teams. Its currently published core automates structural-column numbering, foundation and pile numbering, and two-way Excel exchange. Broader tools presented on the developer’s website extend the concept toward project setup, view and sheet creation, opening and recess modeling, and future automated pile layout.

The add-in’s central design idea is continuity across the structural workflow: marks assigned to columns can drive the identification of supporting pile caps and individual piles; selected model data can move to Excel for coordination and return to the correct Revit elements; and office standards can be reused to establish views and sheets in new projects. This makes ELLAH-M less of a general-purpose utility collection and more of a structural-production toolkit centered on numbering, information consistency, and drawing setup.

Product-status distinction: Autodesk Marketplace currently presents column numbering, foundation and pile numbering, and Excel export/import as the principal released capabilities. The developer’s version 1.3.1 website also advertises Project Setup and FastVoid as available in the trial, while some page sections still label FastVoid and automated pile layout as in development. Teams should therefore confirm the exact feature set in the installed Marketplace build before relying on website previews.

Structural Column Numbering

ELLAH-M scans structural columns, sorts them according to the chosen project logic, and writes sequential identifiers directly to Revit’s native Mark parameter. The tool is intended to replace manual renumbering across multiple levels while preserving a predictable relationship between vertically aligned structural members.

Published Capabilities

• Multi-level numbering: Columns can be numbered across the full project rather than one level at a time.
• Existing-mark continuity: The Marketplace states that the tool can continue from existing manual numbering without overwriting intentional marks.
• Preview before commit: Proposed changes can be reviewed before values are written to the model.
• Native undo: Changes support Revit’s standard Ctrl+Z undo workflow.
• Structural-category targeting: The tool is described as operating on structural columns, limiting accidental edits to unrelated architectural columns or other categories.
• Flexible scope: Developer material describes full-project, single-floor, selected-range, and manual numbering modes.
• Snake Path: A newer interactive method lets the user move the cursor over columns in the desired sequence without clicking every element. Published controls indicate Space can skip a number and Ctrl can finish the path.
• Output choice: Developer demonstration material states that Snake Path can write the sequence to Mark or Comments while maintaining vertical numbering continuity across floors.

Beam Finish Generator: Automatically Create Finish Walls and Ceilings Around Structural Beams

Executive Overview

Beam Finish Generator is a focused Revit productivity add-in developed by DesignLab for automatically creating finish walls and ceilings around structural beams. Its purpose is to eliminate the repetitive process of modeling beam encasement or finish surfaces one beam at a time. The user selects one or more structural beams, chooses an existing Revit wall or ceiling type, and runs one of two commands: Side Walls or Lower Ceiling.

The add-in creates native Revit wall and ceiling elements rather than symbolic graphics. Because the results use project types already available in the model, they can participate in normal documentation, scheduling, material definition, visibility control, and downstream editing. The tool is best understood as a geometry-generation utility: it accelerates finish creation around modeled beams, but it does not design assemblies, determine required fire protection, or verify constructability.

Core Commands and Workflow

Side Walls

The Side Walls command generates four finish walls for each selected structural beam: two walls along the beam’s long sides and two walls closing the ends. The generated walls are offset by half the selected wall type’s thickness so their finish faces align around the beam rather than placing their centerlines directly on its edges. Vertically, the walls are aligned to the beam’s bottom face.

A typical workflow is to select any number of beams, launch Side Walls from the dedicated Beam Finish ribbon tab, choose a wall type available in the active project, and confirm the operation. The add-in then creates the finish walls for every selected beam in one batch. This can replace four manual wall placements—and their associated offsets and height adjustments—for each beam.

Lower Ceiling

The Lower Ceiling command creates one ceiling beneath each selected beam. The ceiling footprint is generated to match the beam’s plan footprint, and its elevation is aligned with the beam’s bottom face. The user selects the beams, chooses an existing project ceiling type, and runs the command for the complete selection.

The command is intended for soffit-like or encasement conditions where the underside finish follows the beam footprint. It can be used independently from Side Walls, allowing a team to generate only vertical finish faces, only the lower horizontal finish, or both.

AutoJoin Manager: Automates Revit’s Join Geometry and Unjoin Geometry Workflows

Executive Overview

AutoJoin Manager is a professional productivity add-in developed by DesignLab for Autodesk Revit. It automates Revit’s Join Geometry and Unjoin Geometry workflows across multiple element categories and gives users explicit control over cutting priority. Instead of joining intersecting elements one pair at a time—and then correcting join order where the wrong element cuts—the user creates an ordered list of categories, optionally narrows each category to chosen element types, and runs the operation across the model in one batch.

The add-in is primarily a model-cleanup and standards-enforcement utility. It is intended for architectural and structural teams that repeatedly coordinate walls, floors, columns, framing, ceilings, foundations, and other joinable categories. Its main advantage is not merely speed; it makes join precedence repeatable. A saved rule set can express a firm or project convention for which categories should cut others, reducing inconsistent results created by manual selection order.

How the Workflow Operates

1. Build the category list. Add the Revit categories that should participate in the operation. Published examples include structural columns, structural framing, walls, floors, ceilings, foundations, and other categories that Revit permits to be joined.
2. Set the cutting hierarchy. Arrange the categories in priority order. The category in the first row has the highest priority and is intended to act as the cutting element when it is joined to categories listed below it.
3. Refine by type when necessary. Any category row can be restricted to selected element types rather than applying to every type in that category. This allows different treatment for items such as particular wall, floor, framing, or column types.
4. Run Join or Unjoin. One command processes the configured categories in batch rather than requiring individual element-pair selections.
5. Monitor progress. A progress window reports processing status and percentage completion while Revit evaluates the model.
6. Review the outcome. A results report separates successful operations, skipped pairs, and failures, including reasons where available.
7. Reuse the setup. The priority list is automatically retained between sessions, avoiding repeated configuration when Revit or a project is reopened.

Core Capabilities

Priority-Controlled Join Geometry

Revit’s native join result can depend on the category combination and join order. AutoJoin Manager formalizes that behavior through an ordered hierarchy. If a project standard requires structural framing to cut walls, or columns to take precedence over floors, the hierarchy provides a repeatable rule rather than relying on each modeler to select the correct element first.

BIM-IT Pipe: Practical Automation for Piping Workflows

Executive Overview

BIM-IT Pipe is a specialized Autodesk Revit add-in developed by BIM-IT for plumbing and piping modelers, MEP engineers, BIM technicians, and coordinators. Rather than attempting full system design or automated routing, it concentrates on recurring production tasks that routinely consume time in detailed modeling and shop-drawing workflows: tagging pipe banks, matching elevations, maintaining spacing and clearance, splitting branches, aligning sections, isolating systems, and applying or displaying insulation. The tools operate on native Revit pipes, annotations, views, and insulation, so their results remain part of the model and documentation set.

The product’s core value proposition is practical automation. Each command addresses a narrow operation that can otherwise require repeated selection, measurement, movement, alignment, visibility adjustment, or annotation cleanup. This makes the add-in most relevant after basic systems and routes have been established, when a team is refining geometry, coordinating congested pipe runs, and preparing readable plans and sections.

Annotation and Documentation Tools

Pipe Size Tag

Adds a pipe-size tag above a selected spot elevation in the current view. The user chooses the pipe-tag type and can adjust offsets. Placement is calculated from the spot-elevation text position, reducing manual alignment. Developer guidance states that the spot-elevation text should be horizontal and its text location set in line with the leader. If the selected tag family wraps its label onto two lines, the computed label height can create excessive spacing; enlarging the label in the tag family and reloading it is the recommended correction.

Tag Pipe Bank

Adds size tags for multiple pipes associated with a selected spot elevation. Tags are stacked vertically in the order the pipes are selected, with configurable offsets and a reverse-order option. This is especially useful for congested parallel services where conventional individual tagging takes time and produces inconsistent arrangement.

Align Section

Aligns a section view to a selected pipe or model line and centers the section on that reference. The command helps a modeler orient working sections to sloped, angled, or otherwise inconvenient pipe runs before making detailed adjustments or preparing shop drawings.

Electrical Panels Manager

Executive Overview

Electrical Panels Manager (EPM), published by BIM_OS, is an add-in for Autodesk Revit aimed at electrical engineers, BIM engineers, coordinators, and model authors. It centralizes electrical-panel data editing, automates recurring panel naming and rating tasks, sizes feeder cables using IEC-based methods, performs voltage-drop and short-circuit studies, and exports engineering reports without requiring the user to leave Revit. The add-in is designed to replace repetitive schedule reading and parameter entry with a single interface that reads model data, calculates results, and writes approved values back to Revit.

Panel Discovery and Data Management

• Automatic panel discovery: Current product descriptions state that EPM can detect panels in the active 2D or 3D view and can switch to whole-project scanning, reducing the need for manual selection.
• Centralized property editing: The interface exposes critical properties such as panel name, location, mains or bus rating, circuit-breaker rating, short-circuit rating, enclosure type, number of slots or maximum breakers, and comments.
• Direct model updates: EPM reads Revit’s electrical parameters and writes edits back to the panel elements in a single transaction.
• Batch processing: Multi-panel selection supports consistent edits and calculations over several panels rather than one element at a time.
• Panel visualization: A Show Panel function highlights or isolates the selected panel in an appropriate view, helping users locate equipment while reviewing tabular information.
• Standardized naming: Auto-naming uses user-defined prefixes, reference codes, separators, start indices, and increments. Panels can be grouped by level, zone, or location reference to align identifiers with project conventions.

Automated Ratings and Connected-Load Workflow

The Auto Calculate or Auto Assign workflow reads connected loads from Revit and uses them to propose mains and circuit-breaker ratings. Marketplace material describes an 80% design-current rule associated with IEC 60364-4-43. This can accelerate initial sizing and improve consistency across a large panel population, but the quality of the result depends on accurate Revit circuiting, load classifications, demand assumptions, supply-system data, and parameter mapping. Calculated ratings should therefore be treated as engineering outputs requiring review rather than unquestioned metadata updates.

Free Bimroom: Thousands of High-Quality BIM Objects w/Seamless Drag-and-Drop Integration

Overview

bimroom is a free Windows add-in from Bimform AG that embeds the bimroom cloud library inside Autodesk Revit. Its primary purpose is to reduce the time designers spend leaving Revit, searching manufacturer websites, downloading family files, organizing local folders, loading content, and later replacing temporary objects. Users can search, filter, preview, place, find, and replace BIM objects from within the Revit workflow. The library combines generic objects for early design with quality-controlled manufacturer objects for later specification, making the add-in both a content-delivery platform and an object-management utility.

Typical Revit Workflow

1. Open bimroom inside Revit. The integrated interface provides access to the online catalog without requiring a separate download-and-load sequence.
2. Search and refine. Locate content by keyword, then narrow results with filters and facets. Preview information before committing an object to the project.
3. Place content. Drag an object into the model; the add-in handles content delivery into Revit, avoiding manual file browsing and family loading.
4. Develop from generic to specified. Use uniform generic objects during concept and design development, then replace them with manufacturer-specific products when selections are made.
5. Manage existing instances. Use Find Similar to identify related content and Replace One or Replace Many to update selected or repeated objects across the project.

Library and Content Strategy

• Broad catalog: bimroom promotes access to thousands of generic and manufacturer BIM objects spanning multiple building-product categories.
• Uniform structure: The platform emphasizes consistent parameter naming and data formatting so objects are easier to search, compare, filter, schedule, and exchange.
• Parametric behavior: Premium objects are described as fully parametric and dimensionally accurate, supporting adjustment within the limits built into each family.
• Model efficiency: bimroom states that its content is modeled cleanly, without redundant geometry, to reduce unnecessary model weight and performance problems.
• Product information: Objects are intended to include the data required for specification and project use, helping reduce later enrichment or placeholder replacement.
• Continuously expanding content: New generic and manufacturer objects are added over time, so search results and product availability can change.

Free Drafted: AI House Generator—Five Complete Editable Model Alternatives w/Documentation “in 45 Seconds”

Overview

Drafted is a free, cloud-assisted Revit add-in for early-stage residential planning. It converts a structured design brief—primarily a room list, optional footprint, and generation settings—into five alternative house-plan concepts in roughly 45 seconds. Unlike an image generator, it returns native, editable Revit geometry, including walls, floors, roofs, doors, windows, and rooms. Its purpose is to accelerate schematic exploration and give designers several BIM-ready starting points rather than produce construction-ready documentation.

How the Revit Workflow Operates

1. Define the boundary. Use Draw Shape to trace a footprint, or omit the footprint and allow Drafted to establish the overall form.
2. Build the program. Add the required spaces, such as bedrooms, bathrooms, kitchen, living areas, garage, and porches.
3. Generate alternatives. Submit the inputs through the Drafted ribbon. Processing occurs on Drafted’s servers and requires an internet connection.
4. Compare five schemes. Each generation round places five alternatives on the Revit canvas for side-by-side review.
5. Iterate. Revise the footprint, room list, or settings and generate another set if the initial options are unsuitable.
6. Develop the selected option. Continue editing the chosen native Revit elements using normal modeling, coordination, and documentation practices.

Generated Content and Deliverables

• Native model elements: Editable Revit walls, floors, roofs, doors, windows, and rooms rather than a flattened image or imported underlay.
• Multiple design options: Five distinct floor-plan concepts per generation round, supporting rapid comparison of adjacency, circulation, footprint efficiency, and program fit.
• Basic project views and documentation: Each option is reported to include square footage, room count, a 3D view, elevations, area plans, and sheets.
• Account synchronization: Generated work also syncs with the user’s Drafted account at Drafted.ai.
• Continued editability: Teams can adjust the generated geometry, replace content with office-standard families and types, and carry the preferred concept into conventional Revit design development.

Free DimGen: Intelligent Annotation Tools for Structural Workflows

Summary

DimGen is an Autodesk Revit add-in published by Revix on the Autodesk Design and Make Marketplace. Public descriptions position it as an intelligent automation tool for structural engineers, BIM modelers, architects, and draftsmen who need to automate repetitive structural dimensioning and tagging tasks in Revit.

Primary Purpose

The add-in is designed to reduce the manual effort required to dimension structural drawings. Instead of placing repeated strings of dimensions and tags by hand, users can run task-specific tools that identify structural elements, relate them to grids or axes, and generate dimensions and related annotation automatically in the active Revit view.

Core Dimensioning Capabilities

• Automatic column and grid/axis dimensioning in the active view.
• Dimensioning for floors, slabs, isolated foundations, and continuous foundations.
• Support for walls, foundations, axes, and linked models.
• Smart offset controls for dimension-line placement.
• Automatic column tagging as part of the column-and-axis workflow.
• Detailed summary reports after running supported tools.

Linked Model and Rotated Element Support

One of the notable claims on the Autodesk Marketplace is support for full linked models and rotated elements. This matters in structural BIM workflows because grids, columns, foundations, and slabs often need to be coordinated against linked architectural or structural models, and not all building geometry is aligned to the project’s primary orthogonal grid. Support for linked and rotated conditions can make automated dimensioning more useful on real projects where geometry is not perfectly simple.

Revit Add-ons Has Competition: Introducing RVT Plugins

So, somebody's stealing food from our babies' mouths... 😉

RVT Plugins is a competing site that bills itself as "your guide to the best Revit add-ins." We thought, perhaps, that the site was started during one of our fallow periods to fill the resulting void. However, the site was apparently established in 2018, while Revit Add-ons was in full swing, so we're not sure what the impetus was. (Revit Add-ons was itself established in 2011, and we made 500 posts in 2018.)

What's the difference? At first blush, RVT Plugins seems to have more product reviews, a lot more. However, upon closer inspection, these are generic enough that they could have been AI generated. Microsoft Copilot will do it for you from available standard Internet sources, just build "format as a review" into the prompt. While we don't have the time it takes to do many reviews here on Revit Add-ons, our reviews are strictly hands-on, and therefore, we hope, worth your time.

We will give props to RVT Plugins for using a very modern blog template, though I think we'll keep our more traditional blog roll format. While our host Blogger is the venerated grandaddy of blog hosting sites, RVT Plugins may be using a more modern hosting service, like Wix. If we were starting today, that's probably what we'd do. 😏 (We hope Blogger doesn't see this...)

Free SheetEX: Batch Export to Popular Formats, Plus DWG Merge & Image Binding

Summary

SheetEX is a free Autodesk Revit add-in presented in public internet sources as a sheet and view export utility. It is focused on speeding up drawing-package output by supporting batch export to common deliverable formats, custom naming and folder organization, and advanced DWG workflows such as merging multiple sheets into one DWG and binding image references directly into DWG files.

Primary Purpose

The add-in is designed to reduce the time and manual effort required to export Revit sheets and views for issue packages, coordination deliverables, consultant exchange, and archive sets. It targets workflows where users need repeatable export settings, organized output folders, and reliable naming conventions instead of manually exporting sheets one by one or renaming files after export.

Supported Export Formats

• PDF exports for drawing issue sets.
• DWG exports for CAD coordination and consultant exchange.
• DWF exports for review workflows.
• IFC exports for openBIM coordination.
• NWC exports for Navisworks-based coordination.
• Image exports such as JPG or PNG, depending on workflow requirements.

DWG Merging and Image Binding

One of SheetEX’s most distinctive reported features is the ability to export separate sheets or merge multiple Revit sheets into a single DWG file. Public descriptions also highlight the ability to bind JPG and PNG images directly into DWG files, creating self-contained DWG deliverables without broken external image references. This is useful when Revit sheets contain raster logos, images, consultant backgrounds, title-block graphics, or other linked image content that must remain visible when the DWG is opened outside Revit.
