Useful for
- • Diagnosing a group that refuses to report a volume
- • Preparing watertight geometry for 3D printing or CNC
- • Making Solid Tools operations succeed
Limitations to know first
- • Not every fault is auto-repairable; some need manual modelling
- • The README documents an Internet Explorer 9 requirement on Windows, a sign of its age
What SketchUp does natively
Entity Info reports whether a container is solid, and Fix Problems catches a subset of faults — but neither tells you where the fault is.
Guides that use it
Each one documents the native method first, so you can decide whether this extension is worth adding for your case.
