Automatic Repair STL

Automatic Repair STL

Automatic Repair STL is the one-click route to a printable mesh: it finds and fixes the classic STL problems — open edges, multiple components — in a single pass, from a panel where you control how aggressive the pass is.

Two precision modes:

  • Document Settings — uses the precision already defined in the document.
  • Custom Settings — lets you set the minimum and maximum edge lengths of the mesh and the decimation level applied while rebuilding it.

After the repair, the panel reports whether the mesh is now suitable for 3D printing: the number of components (a correct STL has exactly one) and whether any open edges remain.

The Print Model

Accept bakes the repaired mesh as a Print Model: a mesh that remembers the repair parameters, the objects it was repaired from and its report. It is still an ordinary mesh for everything else — weight, breakdown, STL export, pricing.

  • It is listed in the Outliner as Print Model, with a Save as STL button that opens a save dialog and writes the mesh straight to an STL file, named after the document.
  • Select it and run ArtisanEdit to reopen Automatic Repair with the same parameters. The panel repairs again from the original objects when they are still in the document, or from the Print Model itself when the originals were deleted on accept; Accept replaces the Print Model in place.
  • Scripts and the MCP repair tool produce the same Print Model.

The command does not work with blocks — if the model contains any, explode them first with Rhino’s ExplodeBlock and then run the repair.

Use Quick Check to find the meshes that need this, and Repair when you prefer to control each fix step by step.
