Ok, I’ve gone back to making some more simple shapes. Joints are easy peasey when they are 90’s, so I wanted to work out some tougher joints. First I set out to build a octagonal column. Here’s the CAD.
Then I moved on to adding a hip roof to a square tower. Here’s the CAD for that.
I was pleasantly surprised when everything snapped together nicely on the first try.
And that’s that. I need to make an octagonal roof now.
