I would like to create beam models having various cross sections on ProE tool.
Can I create a beam model like below by only extrusion?
Can anyone explain what is the best way to model various cross sections of beams?
If pro-e is anything like solidworks then you need to draw a 2D version of the extrusion pattern. In your case, one large square with the 4 smaller squares within it.
Then select the area you wish to extrude and extrude it.
I recommend looking up some basic tutorials for ProE as I'm sure this would be covered in the early stages.
