Text to CAD: describe it, get a verified file.

Describe a mechanical part in plain English and Volex Forge returns a verified, manufacturable CAD file — STEP, STL or DXF — in seconds. Every part is checked, with FEA validated against textbook theory and a proof behind every result. No black boxes.

Try Forge free Check your own STEP file — free Parts from £2.99

No account needed for the file check. Upload a STEP file and we will tell you whether the solids are watertight, how many bodies it really contains, and whether any of them intersect — then delete it.

Don't take our word for it — bring your own file

Every text-to-CAD tool claims its output is good. The claim is unfalsifiable until someone checks, so here is the check itself, free and without an account: upload a STEP file from any CAD system and see what we can actually prove about it.

  • Watertight solids. A file that looks right in a viewer can still be surfaces with gaps — which no CAM or FEA tool accepts.
  • Real body count. Assemblies arrive as one file; knowing it is really fourteen bodies changes what you can do with it.
  • Interference. Bodies sharing solid volume — the defect that turns up on the shop floor rather than on screen.

What it will not tell you is whether the part is right. There is no description of what it was meant to be, so no honest tool can claim that from geometry alone. Saying so is the point: it is the same line Forge draws on its own output.

How text-to-CAD works

From a sentence to a machinable part.

Three steps, no modelling by hand.

1

Describe it

Type the part in plain English — dimensions, features, material. No menus, no sketching, no constraints to fight.

2

Forge builds it

Volex Forge generates parametric, manufacturable geometry and runs verification — dimensional, FEA, thermal and fatigue where relevant.

3

Download, proven

Export STEP, STL or DXF with a proof of every check attached — ready to machine, print or laser-cut.

Output formats

Real files your machines already take.

Manufacturable geometry, not a render — in the formats your existing CAD and CAM tools use.

STEP
Solid geometry for CAD and CNC machining.
STL
Watertight mesh for 3D printing.
DXF
2D profiles for laser and plasma cutting.
Frequently asked

Text-to-CAD, answered.

What is text-to-CAD?
Text-to-CAD turns a plain-English description of a part into a real CAD file. Instead of drawing geometry by hand, you describe what you need — dimensions, features, materials — and get manufacturable geometry to export as STEP, STL or DXF. Volex Forge also verifies the result with FEA checked against textbook theory before you download.
How does text-to-CAD work in Volex Forge?
You type something like "a 40 mm spur gear, 20 teeth, 10 mm bore, 8 mm face width in steel". Forge parses the intent, builds parametric geometry, runs the relevant checks, and returns a downloadable STEP, STL or DXF with a proof of every check.
What file formats can text-to-CAD export?
STEP for CAD and CNC, STL for 3D printing, and DXF for laser cutting and 2D profiles. The geometry is manufacturable, not just a picture.
Is the CAD output actually manufacturable and verified?
Yes. Every part is checked before download — dimensions, and where relevant FEA against textbook theory, thermal and fatigue — and each result carries a proof so you can audit the number instead of trusting a black box.
How much does text-to-CAD cost?
Volex Forge is free to try, with individual parts from £2.99. Assemblies are supported too.
How is text-to-CAD different from traditional CAD software?
Traditional CAD needs you to model every feature manually. Text-to-CAD starts from a description and produces the geometry in seconds — great for rapid parts, iterations and non-experts — while still exporting the same STEP/STL/DXF your tools and machines already use.
