Description
The Mesh Difference command creates a new non-parametric mesh object, a Mesh Feature, that is the difference of two mesh objects: one mesh object is cut from the other.
OpenSCAD must be installed to use this command, and the path to its executable must be set in the OpenSCAD preferences.
On the left two mesh objects, on the right the mesh object that is the difference of those objects if the cube is selected as the main object
Usage
- Select the main mesh object.
- Add the mesh object you want to cut from the main object to the selection. The mesh objects must overlap.
- Select the Meshes → Boolean → Difference option from the menu.
Properties
See: Mesh Feature.
