The MeshSplit command divides meshes into parts with another object.
-
If a curve is selected as splitter, it is "extruded" in the z-direction of the current CPlane to intersect and split the mesh. If the curve is almost on the mesh, it is recommended to use the SplitMeshWithCurve command that pulls the curve onto the mesh for splitting.
-
If the mesh has flipped face normals, the split may fail. Run the Check command to test and UnifyMeshNormals to correct the problem.
Steps
-
Select objects to split.
-
Select cutting objects.
Enter "IP" and press enter to set an infinite plane as the cutting object.
Command-line options
Tolerance
Auto
Uses a tolerance that is more suitable for well-drawn meshes created using document tolerances. The value is computed using heuristics.
Literal
Uses document tolerances. This might not be the best value because meshes often have tiny features that might fall well below the document tolerance.
CoplanarFaces
Keep
Uses coplanar overlaps in the computing of split.
Drop
Discards coplanar overlaps.
CreateNgons
Keeps the split mesh neat by creating Ngons along the splitting edge.
DiscardUnsplitMeshes
Yes
If a mesh cannot be split into multiple parts, the mesh is not changed.
No
Edges are added along the intersections, even if the mesh is not split into multiple parts.
CompleteOpenCuts
Extends incomplete intersections to force splitting the mesh into separate parts.
MarkOpenCuts
Adds object points to help locate incomplete intersections when splitting fails.
