GDML Objects can be created by extruding a FreeCAD sketch

When exported the GDML Object will be created from a series of booleans

Comparison Timings

Timing for extruded sketches, exported as Booleans of solids versus being Tessellated

Simulation timings

With 10^6 geantinos:

extrusions: 7.25 s
tesselation: 17.35 s


With 10^6 2 MeV gamma rays:

extrusion: 17.35 s
tessellation: 146 s
