Assembly3 Workbench

Introduction
Assembly3 is a external workbench that is used to perform assembly of different bodies contained in a single file or in multiple documents.

It was developed as a testbed for the App Link object that was eventually included in FreeCAD 0.19.

Compatibility
Assembly3 was inspired by Assembly2, but it is not compatible with it. If you have older models made in Assembly2, you should stay with FreeCAD 0.16 and use Assembly2 there.

New models developed with Assembly3 should only be opened and edited with this workbench.

Although they may have similar tools, Assembly3 is not compatible with A2plus nor Assembly4. Models created with each workbench should be opened only with their respective workbench.
