- People checking 3D models before printing
- Worth noticing
- It flags boundary and non-manifold edges, but explicitly leaves supports, infill, and final print settings to a slicer.
Field notes
The interface lists measurements in millimeters, centimeters, or inches and warns that STL coordinates may not carry reliable physical-unit metadata. It also describes a repair workflow that merges duplicate vertices, removes degenerate faces, and orients closed shells, with a before-and-after topology report. Its guidance reserves supports, infill, layer height, and final orientation for a separate slicer.
