Sketches with many repeating geometry can really slow down FreeCAD. This is a problem that one of my patreon had when trying to tackle a speaker grill. An additional hurdle was how to apply this to a curved surface. The curves workbench slowed right down with the repeating hexagons so we took a different approach with the Lattice2 workbench
