Auto-Clean is designed to quickly clean up small geometry imperfectionsthat occasionally occur during scanning.
It’s especially useful for larger scans, older projects created before RENDR 3.0, or projects where a few walls need a little help connecting correctly.
Think of Auto-Clean as a first-pass cleanup tool—not a replacement for good scanning technique or manual editing.
Auto-Clean can:
✅ Connect walls that should already be joined
✅ Remove overlapping or duplicate wall segments
✅ Straighten walls that are only slightly off angle
✅ Improve room detection by cleaning up wall geometry
💡 Pro Tip
Run Auto-Clean before manually editing your floor plan.
It often fixes dozens of small geometry issues in just a few seconds, allowing you to spend your time making meaningful edits instead of repairing tiny wall connections.
Best Practices
💡 Start with the default Strength setting before increasing it.
💡 Always review the Preview before applying changes.
💡 Use Auto-Clean after opening older scans created before RENDR 3.0.
💡 If rooms stop generating after several wall edits, running Auto-Clean again can often reconnect small gaps.
💡 Good scans should require very little cleanup. Auto-Clean works best as a finishing tool—not a routine part of every project.
How to Run Auto-Clean
To use Auto-Clean:
Open the desired Space.
Switch to Edit mode.
Select Layout mode.
Tap Auto-Clean.
Enable Preview.
Review the proposed changes.
Adjust the Strength slider if necessary.
Tap Apply to save the changes.
If you exit Auto-Clean without tapping Apply, your floor plan remains unchanged.
Understanding the Strength Slider
The Strength slider controls how aggressively Auto-Clean adjusts the floor plan.
Strength | Recommended Use |
Lower | Small corrections to already clean scans. |
Medium | Best starting point for most projects. |
Higher | Larger cleanup for scans with more noticeable angle or connection issues. |
If the preview doesn’t produce the results you expect, adjust the Strength and preview the changes again before applying them.
What Auto-Clean Fixes
Issue | How Auto-Clean Helps |
Walls almost touch but don’t connect | Connects nearby wall endpoints when appropriate. |
Duplicate or overlapping wall segments | Removes unnecessary wall geometry. |
Slightly crooked walls | Straightens walls that are only slightly off angle. |
Rooms won’t generate | Often restores room detection by improving wall geometry. |
What Auto-Clean Doesn’t Do
Auto-Clean is designed to improve existing geometry—not redesign your floor plan.
It will not:
Rebuild an incorrect floor plan
Move walls to entirely new locations
Replace manual editing
Correct major scanning errors
After Auto-Clean finishes, you can manually adjust any remaining walls using the standard Layout editing tools.
Recommended Workflow
For the fastest editing experience:
Scan the space.
Run Auto-Clean.
Review the preview.
Apply the cleanup.
Make any remaining manual wall edits.
Confirm all rooms are generating correctly.
Continue with room names, flooring, markup, and exports.
Troubleshooting
If… | Try This |
Rooms won’t generate | Run Auto-Clean, then inspect the remaining wall connections. |
Walls still look crooked | Increase the Strength slightly or manually straighten the remaining walls. |
A room disappears after editing walls | Run Auto-Clean again to reconnect small wall gaps. |
The preview doesn’t look right | Lower the Strength or exit without applying the changes. |
Frequently Asked Questions
Should I run Auto-Clean on every project?
No. High-quality scans often require little or no cleanup.
Can I run Auto-Clean more than once?
Yes. It’s common to run Auto-Clean again after making substantial wall edits if room detection changes unexpectedly.
Why didn’t Auto-Clean fix every wall?
Auto-Clean corrects small geometry issues. Larger layout changes should be completed manually using the editing tools.
