Generate a bolted flange
A disc with a central bore and bolt holes on a pitch circle, used to join two components face to face. The bolt circle diameter (PCD) and hole count must match the mating flange exactly.
What it is used for
- Pipe and duct connections
- Shaft and coupling faces
- Pump, motor and valve mounting
- Pressure-vessel connections
Dimensions that matter
| Outside diameter | Overall disc size. |
| Thickness | Resists bending from bolt clamping. |
| Centre bore | The through-hole. |
| Bolt circle (PCD) and hole count | Must match the mating part. |
What you get
A real solid model you can rotate and measure, plus downloadable STEP (machining and CAD), STL and 3MF (3D printing) and DXF (laser and waterjet) files. Optional built-in analysis covers stress (FEA), thermal, buckling, cost and manufacturability.
Before you see it, the built geometry is measured against the dimensions you stated, checked as a valid watertight solid, and — for assemblies — checked for interference. These are geometry and physics checks; they do not confirm the shape matches what you pictured, so review the 3D view or 2D drawing before relying on the part.
Previewing is free. Downloading is £2.99 per part, or unlimited on Pro (£29/month, £290/year).

Common questions
What file formats do I get?
STEP, STL, 3MF and DXF — the formats CNC shops, laser cutters and 3D printers accept.
Can I change the dimensions afterwards?
Yes. Edit the numbers directly, or describe the change in plain English. Every edit is rebuilt and re-checked.
Do I need CAD experience?
No. Describe the part and its sizes in millimetres.
Is it free to try?
Yes — describing a part and viewing the 3D preview costs nothing.
