universal AOE template for DnD

Area of effect template for spells in pen and paper role playing games. Designed specifically for Dungeons and Dragons with a 1 inch = 5 ft grid in mind, but can easily be scaled to accommodate any other scale.

Features:
- 40 ft line
- spheres with diameters 10 ft, 20 ft, 30 ft and 40 ft
- cubes with side lengths 10 ft, 20 ft, 30 ft
- cones of 5 to 30 ft (the cones are kinda wonky though ngl, input is appreciated)

I also shared the corresponding FreeCAD-File so you can easily make adjustments (just modify the parameters in the "val" spreadsheet) and mainly so you can roast my CAD skills. Let me know if you need help with anything or have suggestions.
