Meshes are a very simple kind of 3D object, used for example by Sketchup, Blender and 3D Studio Max. They are composed of 3 elements: points (also called vertices), lines (also called edges) and faces. In many applications, FreeCAD included, faces can have only 3 vertices. Of course, nothing prevents you from having a bigger face made up of several coplanar triangles.
