I do not see any attached images or files?
All of the FEM softwares I am familiar with do their own meshing within the FEM program.
(I use Autodesk Simulation (Algor), Autodesk Inventor, SolidWorks, and Creo Mechanica for analysis of solids.)
What software are you using that doesn't do meshing of the solid for you?
sorry, here is the attachment..
I am using the SAP2000 for FEM and i can not import a 3d solid, which is created from primitives, like a box or a pyramid.
I can only import "the polygon mesh", which is created with the command: 3dMESH, (which usually works with autolisp?)
And my aim is to convert the primitves to a polygon mesh, to avoid the programming with autolisp..
