Mesh Booleans for AutoCAD is a mesh boolean modeling plug-in for AutoCAD®. Mesh Booleans for AutoCAD gives AutoCAD the ability to perform boolean operations between PolyFace Meshes, Polygon Meshes and 3D Solids or a combination of all. The geometry of a solid object can be described in AutoCAD as a 3D Solid, PolyFace Mesh or a Polygon Mesh entity. However, AutoCAD`s solid modeling commands (Union, Subtract and Intersect) work with 3D Solids only.
