How credits work
What credits pay for
A CAD Genie request uses 1 credit, or 2 per image when it has images (up to 4). A STEP file, a drawing file or an STL file over 250,000 triangles uses 1. A Stress, Thermal or CFD study uses 2.
What stays free
Modelling, assemblies and STL files up to 250,000 triangles. If CAD Genie’s first attempt does not build, it corrects it once at no extra credit.
No result, no charge
A request that times out, or that CAD Genie can’t answer, costs no credit, and neither does a file or a study that fails.
Monthly allowance
Free accounts get 25 credits a month and Pro accounts 400. The allowance renews at the start of each month. You can also earn credits by inviting friends (see Questions).
Credit packs
Need more? 30 credits for US$15, 60 for US$28 or 120 for US$50, on any plan. Bought credits never expire and are used after your monthly allowance. Add them in the WebCAD app: Add credits, next to your credits in CAD Genie.
Cancel anytime
No annual contract. Change or cancel any time from Manage subscription; Pro runs to the end of the period you paid for. All payments are final.
Questions
Do files cost credits?
From October 22, 2026, yes, on every plan: a STEP file or a drawing file uses 1 credit, and so does an STL file over 250,000 triangles. Smaller STL files stay free.
Can I earn free credits?
Yes. Invite a friend: they get 25 free credits, and you get 50 once they build something and come back on another day, for up to 5 friends. Your invite link is under Invite friends, next to your credits in CAD Genie.
What do I need an account for?
CAD Genie, files and studies. You can model without one.
Which currency are prices in?
US dollars. Checkout can show the amount in your own currency.
