How do I repeat an extrude around a sweep? Vents in circular table mic/speaker

Recommended Posts

This is a STEM table speaker/microphone.  I created two sweeps so i could texture them differently and married them with a bitmap on top, but I would like to put the vents in around the bottom piece.  Could someone give me an idea how I could do this without trying to intersect solids 500 times? Thanks.

Hard to tell from the image is all the vents are the same, but it they are, just create one of them and then do a circular array with rotation to get a "fan" of objects. Select the "fan" and the bottom extrude and Subtract Solids. I just used an extruded rectangle for the "cutting" object(s).

Thank you very much, I got both these methods to work, however, I had to do a bit of research.  I was not able to Modify>Subtract Solids, unless I converted the sweep to a mesh.  Could anyone explain why this is?


You should be able to Subtract Solids using a sweep. Its hard to know why you couldn't without a file. I'm surprised you could use Subtract Solids with a mesh since a mesh is not a solid. In the future I would convert an object to a generic solid if its giving you trouble.
