 * Assembly4_0.19.png
 * Assembly4 is an assembly workbench created by developer, that uses realthunder's "App::Link" object and many other changes to the base FreeCAD system, particularly the new expression engine. Because of this, Assembly4 doesn't work with versions below 0.19. Assembly4 can be installed from the Addon Manager.
