Write what you need in plain language. EngiPro sizes it against the standards, builds it in SolidWorks, checks the result against its own math, and hands you the SolidWorks model and the STEP file. The modeling hours disappear.
No CAD license needed. Create an account, pick a plan, and start in the chat.
Your request
The built body is measured from the geometry and checked against the request before it is delivered.
Draft output. A qualified engineer must review and approve it before anything is made from it.
Every part follows the same path. Nothing in it depends on you knowing SolidWorks, or on the model guessing well.
Step 1
Say what the part is and what it has to do. English, Persian and seven more languages.
Step 2
Missing dimensions come from the standards tables or from 242 engineering calculations — not from a guess.
Step 3
The spec is validated and the mass predicted before anything opens. Invalid geometry is caught here, and never counts against your quota.
Step 4
A real SolidWorks session builds the part in its own isolated process, with a time limit and a queue of one.
Step 5
The built body is measured and checked against the request. Then you get the SolidWorks model, the STEP file and a preview image, plus the flat pattern for sheet metal.
Three engines, one answer. The language model only describes the part — it never runs anything on our machines.
242 calculations from Shigley's Mechanical Engineering Design, 11th edition, across twenty chapters. Every number the model needs and cannot invent comes from here, with the assumptions written down next to the result.
Pipes, bends, tees, reducers, collars and flanges to ISO 2531, from DN80 up. Ask for a DN300 bend and you get the real wall thickness, not a plausible one.
The native SolidWorks model (saved in SolidWorks 2025, opens in 2025 or newer), neutral STEP geometry for Inventor, CATIA, NX, Fusion or older SolidWorks, a preview image, and for sheet metal the flat pattern ready for the laser or the punch.
Parts, specs and revisions belong to your account. Enterprise teams can run the whole build layer on their own machines, inside their own network.
Same engine on every plan. A part counts only when you actually receive it — failed builds and repair attempts are free.
Coursework, projects and a thesis that's due sooner than you think.

The first 200 annual subscribers keep that price through every future price list. In return we ask for one thing: tell us when the engine gets something wrong.
— of 200 seats left
Twenty-five seats or more for a department, with one invoice and a shared part library. Each seat covers coursework: 30 questions a month, 4 worked end to end. Your students keep their work when the term ends.
Billed in US dollars and paid in USDT (TRC20) for now. One price in every country, and invite codes work the same everywhere.
Every subscriber gets an invite code. Whoever uses it saves 25% on their first month, and 5 extra parts land on your account.
Your plan is switched on as soon as the payment arrives. Card payment is coming.
No. The build runs on our machines and you download the result. If your company would rather keep everything inside its own network, Enterprise runs the same build layer on your hardware, with your license.
Only a part that builds and passes verification. Spec checks, calculations, failed builds and the repair attempts that follow them are all free — you're charged for delivered geometry, not for trying.
It gets caught before it reaches you. SolidWorks must rebuild the part without errors, the built body is measured, and a rendered view is compared with your request. A part that fails a check is repaired and rebuilt — and if it still does not match, you're told what's wrong instead of being handed a bad model. A part counts against your plan only when it is delivered.
Any language you write in: the answer and the design report come back in it. The chat itself is in English and Persian.
Yes. You get a native, feature-based model with a readable tree, not a dead solid. Open it, change a dimension, keep working — or send the change back as a sentence and let EngiPro rebuild it.
Not without an engineer checking it first. The platform verifies that the geometry matches its own calculations — it does not decide whether the part is right for your load case, your material, your code or your application. A qualified engineer has to review and approve the output, and that engineer carries the professional responsibility for it. We accept no legal liability for designs produced here.
You do, on every plan. We don't train on your specs and we don't reuse your geometry.
Bring the part you've been putting off. It'll be in your hands in a few minutes.
