Fixing geometry using the Mesh Toolkit (MTK)

About this document

The 'Mesh Toolkit' includes a wide variety of operations that can be used to prepare and fix meshes.

Fix geometry via 'Mesh' window

Using the Mesh Toolkit operation is useful for multi-step mesh operations or if the operations need to be saved in a profile for batch processing. All of the mesh toolkit operations are, however, also available for direct use in the viewport by navigating into the 'Mesh' window located at the top of the application.

Settings

Vertex Welding: Welds vertices together if they are below the specified distance threshold. For more information on vertex welding, please navigate to the following article: Vertex Welding

T-Junction Healing: If set to value > 0, automatically heals t-junctions if the vertex edge distance is below the specified threshold

Remove Degenerate Faces: If set to value > 0, automatically removes degenerates if two or more corners are shared by a polygon

Fix Non-Manifold: Rebuilds the mesh geometry to be manifold

Conform Normals:  Conform the normals of the selected mesh. 

Conform WInding Order: Conform the winding order of the selected mesh. 

Flip Normals: Flip the normals of the selected mesh. 

Flip Winding Order: Flip the winding order of the selected mesh. 

For more information on fixing surface normals and winding orders, please navigate to the following article: Fixing Surface Normals

Fill Holes: Closes mesh boundary holes. For more information on filling holes, please navigate to the following article: How to close holes?

Normal Healing Mode: Fixes normal anomalies on the surface. 

Recalculate Normals: Recalculates the surface normals using the specifies hard angle threshold 

Combine Meshes: Combine selected mesh nodes into a single mesh node

Split Meshes: Split mesh by adjacency

Split By Material: Split mesh by material

Minimum Radius: Remove meshes below the specified BSR threshold

Minimum Face Area: Remove polygons smaller than the specified surface area. Can be used to remove degenerate faces

Translate: Translates the mesh in units

Rotate: Rotates the mesh in degrees 

Scale: Scale the mesh by a factor of 'x'
