I'm working on a number of icons for 3-D printing. I'm having an issue where I've traced out the object as linked edges and vertices, and then gone through the following process:

Convert to curve. In the curve options, extrude to add "height". Convert back to mesh. Apply solidify modifier.

This has left me with an object that is as I need it, but has also left some self-intersecting geometry that I would like to remove, so that I'm not getting overlapping faces inside the geometry etc.

I've tried the: Ctrl+F > Intersect (knife) but it doesn't seem to be simplifying the geometry as I need it Boolean modifier using a cube around the object, and doing all three available operations. Nothing seems to happen here.

I have the .blend file here in a dropbox folder https://www.dropbox.com/sh/c05dvx6vforyx1y/AAB_bYT-gw0Z40l0AGKju9tga?dl=0

  • $\begingroup$ Hello :). This definitely looks like a perfect job for the Boolean modifier. You just need to separate your mesh into different objects for it to work. $\endgroup$ – ᴊᴀᴄʜʏᴍ ᴍɪᴄʜᴀʟ Dec 9 '19 at 21:56
  • $\begingroup$ Ah you're definitely right. I hadn't thought of that. That gets me new vertices at the intersect points, and though it leaves the intersect area with a lot of mess, it's pretty easily manually cleaned up so that will do nicely. Thank you! :) $\endgroup$ – ChickenMacNugget Dec 10 '19 at 18:20
