Mesh Repair

The MeshRepair command opens the Mesh Repair panel.

The Mesh Repair panel contains mesh information display and repair commands to make repairing bad meshes easier

Some STL/SLA printers have problems if meshes contain many long, thin facets. These facets can slow the printer down, produce odd results, or run the printer out of memory.
The MeshRepair command may be useful when tuning up meshes for STL/SLA printing.

Steps

Select a mesh and click Check Mesh.
Information about the mesh is displayed, including the Edge Analysis control.
Select problems to fix, and click Repair.
When all possible problems have been repaired, click Next.
Use the Advanced Repair Tools to edit the mesh, and then click Finish.
