Determining projected area
Determining projected area
(OP)
If I have a 3D assembly and would like to determine the projected area normal to a bunch of different planes, does ACAD have any means to do that?
Something like translating a surface along a vector and then creating 2D closed PLINEs whereever the plane had intersected with an element from the assembly.
What I'm actually trying to do is determine the drag on an antenna structure when the wind is approaching from different angles.
I think I could've done it with surfaces in old-school UGII (circa 1990) but don't have any idea if I'm wasting my time thinking along these lines with ACAD.

RE: Determining projected area
But "solprof" does a 2D conversion of a 3D model.
Actually its copy overlaid on top of the 3D model.
Maybe someone else might have some more insight.

RE: Determining projected area
As it turns out, solprof is exactly what I used! It was a little more "manual" than I'd have wanted but it certainly did the job.
Thanks again for the response.
