@rei_jen I think you will find some clarity if you utilize folders in your feature tree. This will help organize your thoughts and design intent. So you can focus on specific areas or parts.

In the latter case, instead of using planes, you could also use mate connectors to locate holes for your screws. Easier to control and you could use variables to define the radial position together with the cylinder diameter of E.G. Part 6, so they always match.

With things circular, it might somtimes be a good idea to use a cross section sketch and then rotate it. It usually saves a lot of translate features, and you can create better relationships between the parts (E.G Offsets and such) because you can define their basic dimensions in either one common sketch or in separate sketches layered on to of each other, but still having dependencies.

Also found this Feature script from CADSharp - may give them a call about how to adaptor commission it to my specific needs.

This question is not the most specific one I read today, though: Why not make a sketch?
