Check, Repair and Edit STL Meshes
Choose the operation your mesh needs: diagnose topology, apply defined cleanup, change placement, reduce triangles or reorganize components.
Diagnose and clean up
Check reports defects without changing the file. Repair removes supported triangle defects with optional welding and limited orientation correction; it does not fill holes.
Transform and reduce
Editor changes scale, rotation and position. Simplifier reduces triangles within an estimated error budget. Both provide a preview to inspect before export.
Separate and combine
Split exports edge-disconnected components. Merge collects files in their existing coordinate space. Neither cuts geometry nor performs a boolean union.
