Volex Labs / Forge / Flange generator — text to CAD.

Flange generator — text to CAD.

Give Forge the outside diameter, bore, pitch-circle diameter, number of bolt holes and hole size, and it returns a clean flange as a STEP solid or a DXF profile — ready for turning, laser cutting or waterjet.

Bolt patterns are placed exactly on the PCD and evenly spaced, so the mating parts line up without you touching a sketch.

Frequently asked

Can I set any bolt count and PCD?
Yes — bolt count, hole diameter and pitch-circle diameter are all parameters. Forge spaces the holes evenly on the PCD automatically.
Can it do a blind or counterbored flange?
Yes. Describe counterbores, a raised face or a blind bore in the prompt and Forge builds them into the solid.
Is the DXF ready for laser cutting?
Yes — the DXF is a clean closed-profile with the bore and bolt holes, scaled 1:1 in millimetres, ready to drop into a cutter.
How much is it?
Free to try; a downloadable flange is from £2.99.
