How to Extrude?

Jim57 · 18 Oct 2010, 03:32

I'm trying to model a carving to show a CNC operator. I've outlined it and made a profile that I'd like to extrude over the outline. Problem is, I can only extrude the round end. No matter which Extrusion Tool I use, I can't select the straight sides.

I'm suspecting Extrusion Tools were not made to work a straight side. Can anyone give me a hint about how to form this?

Thanks,

Jim

those lines need to be curves/polylines..

right click a line then divide it into say 6 or seven parts then weld the segments together..
you'll now be able to use it with extrude edges..

Cool.

Thanks, Jeff.

It's probably too late now but I made a similar shape using Chris Fullmer's Simple Loft which didn't require dividing the straight lines. I only created half the shape as a component and then copied and flipped the copy to keep the file size smaller. I was making 12 copies of the shape, though.

I did a tutorial showing how I made this which I can link to if anyone wants to see it.

Yeah, I'd like to run through that tutorial, sir.

Sir? You make me feel like a real old guy, Jerry.

Take a look at this. Clearly it isn't the only way but it works for me.

Pardon me. It's time for me to take my Geritol.
