AI Space Takeoff
AI Space Takeoff uses computer vision to automatically identify rooms and spaces on your floor plan drawings, saving time on manual space creation.
How It Works
Section titled “How It Works”Image Analysis
Section titled “Image Analysis”The AI analyzes your floor plan to identify:
- Room boundaries (walls, partitions)
- Door locations
- Labels and room names
- Typical space patterns
Space Detection
Section titled “Space Detection”For each identified space:
- Creates a polygon boundary
- Calculates area
- Reads the room name from the drawing label
- Applies the envelope types you selected
Review Process
Section titled “Review Process”You review the generated spaces before they’re added:
- Toggle each space to include or exclude it
- Approve to keep the included spaces
- Reject all to discard them
Using AI Space Takeoff
Section titled “Using AI Space Takeoff”Starting Takeoff
Section titled “Starting Takeoff”- Navigate to Building Model > Spaces
- Open the sheet you want to analyze
- Click the Auto Takeoff Spaces button (the wand icon) in the toolbar
Takeoff Options
Section titled “Takeoff Options”In the Auto Takeoff Spaces dialog, choose:
- Scope - apply takeoff to all levels, or to the current level only
- Wall Type, Window Type, Roof Type, and Slab Type (all optional) - envelope types assigned to the generated spaces. Roof types apply to the top floor only; slab types to the ground floor only.
Click Run to start the analysis.
Processing
Section titled “Processing”Wait for analysis:
- A progress indicator shows status
- Larger drawings take longer
- You can cancel a run in progress
- Results appear when complete
Reviewing Results
Section titled “Reviewing Results”After processing, the generated spaces enter a review mode (Reviewing Level N). Each generated space is marked as either Included or Excluded, with a legend showing the two colors.
Toggle Spaces
Section titled “Toggle Spaces”- Click any generated space to toggle it between Included and Excluded
- Only the included spaces are kept when you approve
Approve or Reject
Section titled “Approve or Reject”- Click Approve (or press Enter) to add the included spaces to the model
- Click Reject all (or press Esc) to discard every generated space
Refining Spaces
Section titled “Refining Spaces”Approved spaces behave like any other space — refine them with the standard editing tools:
- Boundaries - select a space and drag its vertices to adjust the outline
- Space Type - change the assigned type from the space’s properties
- Name - rename the space from its properties
Best Practices
Section titled “Best Practices”Drawing Quality
Section titled “Drawing Quality”AI works best with:
- Clear, high-resolution images
- Visible room boundaries
- Legible text labels
- Standard architectural conventions
Optimal Use
Section titled “Optimal Use”For best results:
- Use standard floor plans
- Ensure scale is set correctly
- Take off one level at a time for large buildings
Review Carefully
Section titled “Review Carefully”Always verify:
- Boundaries match the drawing
- Space types are correct
- Areas are reasonable
- No spaces are missed
Troubleshooting
Section titled “Troubleshooting”Poor Detection
Section titled “Poor Detection”If spaces aren’t detected well:
- Check image resolution
- Verify scale calibration
- Take off a single level at a time
- Fall back to manual drawing
Incorrect Boundaries
Section titled “Incorrect Boundaries”If boundaries are wrong:
- Approve, then adjust the boundary
- Or reject and draw manually
- Report for AI improvement
Missing Spaces
Section titled “Missing Spaces”If spaces are missed:
- Draw them manually
- AI may miss unusual shapes
- Small spaces may be overlooked
