Your own 3D parametric modeler.
FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.

This absolutely. Using variables is a very powerful feature which enables robust, solid and parametric modelling. The way it is implemented currently, however, is very crude. I have also had issues where when a cell refers to another cell further down in the spreadsheet, all sorts of mysterious bugs occur.
Would be nice if someone would implement a proper solution for this. I'd be willing to chip in on financial support if that would be required.
