I have the base to a wire spool that I am trying to cut a channel out of for a semi-rounded center post. I have made the center post and the base in Sketchup (albeit painstakingly), but have hit a wall trying to cut out the outline (as seen by the template) so the center post may sit in the base about 3/8". Does anyone have any advice on how to accomplish this?
I started using Sketchup about two weeks ago, so I am still learning its inner workings. I have made a couple sketches already, but none with extensive circle work like this.
