What is a polyface mesh in AutoCAD?
AutoCAD has a polyface mesh entity (PFACE comand) which is capable of describing a mesh object, something that other CAD systems usually call “polygon mesh”. Basically a collection of triangle and/or quad faces connected to each other by common vertices. … The polyface mesh entity cannot have more than 32,767 vertices.
How do you create a mesh in AutoCAD?
You can create mesh objects using the following methods:
- Create mesh primitives. Create standard shapes, such as a box, cone, cylinder, pyramid, sphere, wedge, and torus (MESH).
- Create mesh from other objects. …
- Convert from other object types. …
- Create custom meshes (legacy).
How do you cut a polyface mesh in AutoCAD?

What is mesh in design?
Mesh generation is the practice of creating a mesh, a subdivision of a continuous geometric space into discrete geometric and topological cells. Often these cells form a simplicial complex. Usually the cells partition the geometric input domain. Mesh cells are used as discrete local approximations of the larger domain.
