FAQ
Can I set an exact height?
Yes — scale by factor or to a target dimension, depending on the controls.
Is it local?
Yes, scaling runs in your browser.
Limitations
- Uniform scaling (no per-axis stretch here).
- No mesh repair.
- STL files carry no unit information: confirm the unit (mm by default) in your slicer.
- Per-axis (X/Y/Z) scaling is available for non-uniform resizing.
