SolidWorks Assembly & Drafting

I have a complete set of 3D mechanical component models and now need them brought together into a single, fully-constrained assembly in SolidWorks 2019. The goal is to prepare a prototype, so the fit, clearances, and motion studies (if any) must be accurate enough to guide first-article fabrication...
