What is a polyface mesh in AutoCAD?

PFACE automatically breaks them into multiple face objects with the appropriate invisible edges. Faces with one or two vertices behave like point or line objects without the special properties of Point Display modes or linetypes. You can use them to embed wireframe images within a mesh.

Why do we do meshing?

Finite Element Method reduces the degrees of freedom from infinite to finite with the help of discretization or meshing (nodes and elements). One of the purposes of meshing is to actually make the problem solvable using Finite Element. By meshing, you break up the domain into pieces, each piece representing an element.
