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.

Draftmate: AI for Sketch or CAD Plan to Revit Model

Editor's Note: whenever I check Linkedin, which is several times a day, there are new posts about AI and Revit (or related product) modeling. It's impossible to keep up. Ironically, almost all of these modeling examples are of recreating existing buildings or details. Draftmate stands out as an AI tool tailored for converting sketches or CAD plans into new design BIM models. Read on for details.

Summary

Civly Draftmate AI, based on information available from its website, is best understood as an AI-powered BIM drafting and coordination platform. Civly positions the product around moving from sketches, CAD files, or early design intent into editable, coordinated BIM outputs while keeping human professionals in control of approvals.

Primary Product Positioning

Civly describes itself as a BIM drafting and coordination platform for engineering teams. Its public messaging emphasizes moving from drafting to designing, creating one source of truth, and helping architecture, structure, MEP, engineering calculations, and local compliance checks stay coordinated within a shared BIM baseline.

Relationship to Revit

The civly.dev website describes a workflow that creates full editable, compliant BIM models from CAD, Rhino, sketches, or CAD plans.

Core Capabilities

• Transforms sketches and plans into structured model proposals.
• Supports discipline drafting across architecture, structure, and MEP.

Kobi Toolkit for Autodesk Revit: A Broad, All-in-One Productivity Suite

Summary

Kobi Toolkit for Autodesk Revit is a productivity add-in from KobiLabs designed to enhance BIM workflows, reduce repetitive tasks, and extend Revit’s native capabilities. According to KobiLabs and the Autodesk App Store listing, the toolkit includes nine toolsets and more than 40 individual tools focused on BIM management, QA/QC, analysis, reinforcement, annotation, modification, view control, selection, and content administration.

Purpose and Positioning

The toolkit is intended for Revit users who need practical utilities that save time during model setup, documentation, model checking, data editing, and content management. Rather than focusing on one narrow workflow, it functions as a broad all-in-one productivity suite for design and BIM teams. Its strongest value is in helping users complete common model-management tasks faster and with fewer manual steps.

Main Toolsets

Kobi Toolkit is organized into nine toolsets: BIM Manager, QA & QC, Analysis, Reinforcement, Annotate, Modify, View, Selection, and Content Admin Kit. This organization makes the toolkit applicable to multiple stages of a Revit project, including project setup, model production, coordination review, documentation, reporting, and content library maintenance.

Key Features

BIM Query

BIM Query is one of the toolkit’s central features. It allows users to edit type and instance properties for selected Revit categories in a spreadsheet-style interface. The built-in editor supports common Excel-like functions such as sorting, filtering, and copying parameters. Users can also export schedule or model data to Excel, update it externally, and bring the revised data back into Revit. This makes BIM Query valuable for bulk parameter editing, schedule review, model data cleanup, and reducing repetitive manual property changes.

Spazio: Extract and Regenerate Rooms Across Floors, Buildings or Projects

Summary

Spazio is a Revit workflow tool designed to eliminate one of the most repetitive tasks in architectural practice: rebuilding room layouts that have already been designed, coordinated, and documented in other projects. Instead of manually recreating common room types—such as hotel guestrooms, hospital wards, apartment units, or other repeatable spatial modules—Spazio allows teams to capture the layout once and reuse it across future projects.

Core Purpose

In many architectural and BIM workflows, recurring room types require significant duplicated effort. Designers and modelers often need to redraw boundaries, reposition furniture, reload or re-specify families, and place fixtures and equipment from scratch even when the layout has already been resolved elsewhere. Spazio addresses this inefficiency by turning a completed room layout into a portable package that can be stored, shared, filtered, previewed, and placed in another Revit model.

Extract and Export Workflow

The workflow begins inside a Revit model containing placed rooms. With the Extract & Export command, Spazio scans the model and identifies each room along with the related layout information. It collects furniture, lighting fixtures, electrical equipment, plumbing fixtures, mechanical equipment, and boundary walls associated with the selected rooms. The extraction window presents the available rooms with their areas and element counts, helping users decide which layouts are worth packaging.

After selecting the desired rooms and assigning a filename, Spazio exports each room as a standalone .spazio file. These files use a plain JSON format, making them portable, readable, shareable, and suitable for archiving or version control. This approach allows firms to build reusable room libraries without locking the information into a single Revit project.

Free Engineering on Demand Add-in – Instant Feedback for Architects on HVAC Space Requirements

From the Autodesk App Store:

Description

Engineering On Demand puts the architect back in the driver’s seat by giving them instant feedback on HVAC space requirements.  The plugin does this by producing a separate, automatically generated, HVAC model based on the architect’s model.  It then imports “Placement Blocks” that represent the size and shape of the HVAC space requirements into the architectural model, which the architect can then move around the project to better fit the building.

As the project grows, changes and information is added, the architect can re-run the plugin to see the impact on the HVAC space requirements.

The plugin can be used with “rule-of-thumb” engineering values, so even if you don’t have windows or thermal properties defined yet, it can still provide a good estimate of mechanical room space requirements.

The engineer who receives the model can then use Ripple’s HVAC Toolkit to make any modifications they see fit. This fosters better communication between the architect and engineer, which leads to a smoother and quicker design process.  Most importantly, it removes surprise mechanical room requirements that always seem to come at the end of the job.
