Starting to work on new tool cabinet design in FreeCAD. Currently just using the spreadsheet to setup variables before I start actually drawing.

I really want to set the finished product dimensions, and use variables to determine drawer sizes (by type) and their placement. I can do something like:
* Drawer_Deep_Wide (>= 20 cm deep)
* Drawer_Medium_Wide
* Drawer_Shallow_Wide
* Drawer_Shallow_Narrow (to place 2 drawers side by side

and so forth.
