1. Implement the Section Line and it's connection to the drawing view better. Currently to even access the section line sketch requires going through the section drawing view, whereas it is a clearly visible object on the screen. To currently allow an end user to select the section line requires getting them to select line segment that makes up the section line, and compare that to all sketches within section views (accounting for the different scale) in order to access the section view info from the section line, whereas it is all in the right click menu in the UI.
2. Thread feature needs to exist in the Assembly/Weldment Machining state
3. The parts list cells need to have some static/override capability so we can easily check if they are overridden.
