create an STL file
it's an easy question, but i couldn't find an answer on the forum:
i need to create and stl file (for snappyHex) of a rectangular parallelepiped keeping the surfaces separated to allow force coeffs to gives me the force coefficient of each face.
I'm able to use AutoCAD, but when i create the stl it asks me to use a volume, so all the faces got "merged" in one surface.
Is there a way to do this with AutoCAD? Or have I to use another program? In case, can you tell me an easy one to use?
Thank you very much
for such a simple case you can do it by hand or set up a script. Find here the stl file for 2 faces:
Thank you very much. For this first phase I'll try to do what you say.
For more complex cases (that i'll have to face later) instead, how can i do?
CAD software for generating STLs
It has to be a solid, not just a collection of edges. Its been a while since I've used AutoCAD, but I think by default you just get a collection of edges. You can do solids with AutoCAD, but Inventor (also Autodesk), solidworks, etc, are made for solids modeling. There are many open source and free options for solids modeling CAD software, here are some (from this thread):
