SheetMetalCone

Sheet Metal Cone

This extensions draws the 2D shape which is required to form a 3D cone (or truncated cone) after it's cut out (of whatever material).

It can be used to generate a sheet cutting layout for a (truncated) cone. The extension unfolds a frustum (=truncated cone) or a cone (if cut diameter=0) and generates a sheet cutting layout or flat pattern projection that can be rolled or bend up into a (truncated) cone shape.
