Std MergeProject

Description
MergeProject takes the contents of a FreeCAD project and merges them into the currently open one.

How to use

 * 1) Start with a currently open document.
 * 2) Then go to the menu,.
 * 3) A dialog will pop up asking you for the filename and location of the FreeCAD project to be merged into the current one.

Limitations
Since the names of the objects in the merged project will be changed to match the scheme in the existing project, links to external geometry may get lost.
