 * A2plus provides tools to create multi-part assemblies. It is a fork and extension of the older Assembly2 Workbench.
 * Assembly3 (github link) is in development and requires a forked version of FreeCAD with some core changes to the source code. It is the most complex solution and supports things like interactive kinematics.
 * Assembly4 (github link) is a solution based on the enhanced expression engine and the App Link object developed in the branch of Assembly3. Assembly4 does not work with a proper constraint solver, instead it uses the expression engine to position bodies with respect to Local Coordinate Systems (LCS); this is computationally friendly, and should allow for creating large assemblies with many parts. Assembly4 is the newest of the assembly workbenches; initially it served as a demonstrator project, but since 0.19 it is now more feature complete, and it is now installable from the Addon Manager.
