I modeled a part using sketchup web. I'm not experienced so I eventually fumbled my way through.
I have a small dome with 3 components connected to it. First print left some space at the connections and the parts fell off.
I eventually figured out how to make sure the parts were solids and then used the union tool to make it one complete part. Was better, but not perfect.
2 Questions...
1. Is there a way to tell simplify to make just those areas have a higher res or something so the connections are better?
2. My last drawing edit has the longer top part showing up great, but when I do a print preview, that part disappears?
I'll attach the part and some screen shots
(I dont have simplify on work pc so I can not post a screen shot)
