3dFace - Creates a three-sided or four-sided surface in 3D space.https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-5E88BB23-9110-45FB-B54A-3FF2E2002585-htm.html
Mesh - A mesh model consists of vertices, edges, and faces that use polygonal representation, including triangles and quadrilaterals, to define a 3D shape. Unlike solid models, mesh has no mass properties. However, as with 3D solids, you can create primitive mesh forms such as boxes, cones, and pyramids.https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-A6232957-5039-4AB7-8B1D-8FD0AD98F77B-htm.html
A surface is a 3D object that is an infinitely thin shell. There are 2 types of surfaces: procedural and NURBS.
Procedural surfaces can be associative, maintaining relationships with other objects so that they can be manipulated as a group.
NURBS surfaces are not associative. Instead, they have control vertices that allow you to sculpt shapes in a more natural way.https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-8218FF9A-6F05-47E7-A39C-47D342B942EB-htm.html
Solid - A solid is a 3D object that has mass
