I'm having trouble making a 3d power button symbol. I want it to look similar to this one. Here is the .blend file I'm working with, if this helps anyone understand what I'm trying to do.
Using the cuboid that's over the letter 'o', I can cut out the portion of the letter 'o' that the cuboid occupies, however, the remaining ends of the letter 'o' are left open.
I can't find a way to fill the ends, and preferably round the ends. If anyone can show me how to do this, that would be a great help!
