"""Add multiple blocks from their representation as as Rhino meshes.
Parameters
----------
guids : list of str
A list of GUIDs identifying the meshes representing the blocks of the assembly.
Returns
-------
list
The keys of the added blocks.
Warning
-------
This method only works in Rhino.
Examples
--------
