To Stitch Triangles

Merge open triangle edges very close and mostly parallel to be one common edge

Corners and edges of adjacent triangles are merged. If the corner of two adjacent triangles are not in the exact same location, the corners are moved together, which can slightly distort the shape of the part.

1. Select the part to repair.
2. From the main menu, choose Prepare > Repair Part.

   The repair module loads.

3. From the main menu, choose Repair > Stitch Triangles.
   • Specify the tolerance which defines the maximum distance corners may be moved.
     Note: The tolerance cannot be exactly zero.
   • If at least two triangles are selected, you can enable Selected Triangles only to only apply the stitching operation to the selected triangles. If disabled, the operation is applied to all triangles.
   • Enable the Ignore Orientation check box to connect triangles with opposing normals. Please note that this may generate meshes that include triangles with inverted normals, which should be addressed afterwards.
4. Click OK to execute stitching based on your settings.
5. In the context view, click Apply Repair.
6. Choose from the three actions:
   • Remove old part: Creates a new part while deleting the original part.
   • Keep old part: Creates a new part and keeps the original part.
   • Keep and compare: Creates a new part and keeps the original part. It also launches a mesh comparison on these two parts.
