Upcoming FreeCad Ver 0.22 and Ondsel have much improved "in built" Assembly Workbench. This allow easier intuitive approach to assembly joints with out local coordinates systems. Ondsel already has this Assembly Workbench in it's standard workbench package.

Also, it allow dynamically move/rotate parts in the workspace to evaluate the assembly kinematics which is a gamechanger compared to prior addon assembly workbenches.
