While you bulid 3d bodeies and component , it may be noticed that there are long list of bodies , sketches , components
For example : There are sketches use to create openings , sketches use to make pipes ,...etc
My suggestion is to create null nodes to bring all same skeches together under one parent node so browser will be more organized and clear .on the other side renaming one node is easier than reanaming a lot of drawing content.
