Analysis & thresholds
Thresholds

Copper faces exceed the support angle. Red faces are degenerate triangles.

Load a model to see analysis.

Repair first, then print

  • Repair mesh runs free in your browser. Downloading the repaired STL uses one of your 3 free exports.
  • The quick analysis is only a hint — it can miss defects, so Repair stays available whenever a model is loaded.
  • Overhangs and thin walls are not auto-fixed. Re-orient or thicken in CAD if those warnings remain after repair.
  • Files stay local. After download, repair then cut oversized models with the STL Cutter.
