From download to your first part.

1. Install on a Windows PC

Download the Windows installer and install into a new empty folder. ShapeForge currently supports Windows 10/11, 64-bit. The early release is unsigned; inspect the publisher warning and download checksum before deciding whether to run it.

A 127.0.0.1 address belongs to the computer running the app. Your friend needs their own installer; your local address does not open your copy on their computer. The Windows installer does not run on a phone.

2. Try full CAD without a card

The app includes a 14-day full CAD evaluation with STEP, 3MF, drawings and advanced workflows. Eligible signed-in accounts can also try three free cloud AI requests when the service is available. Your trial never starts a paid subscription automatically. Basic CAD, editable project files, recovery, STL export and the deterministic local assistant remain free afterward.

3. Connect your account

1. In ShapeForge, open Account & activation.
2. Choose Sign in & activate this device, then open the secure activation link.
3. Sign in and approve only the code shown in the app you opened.
4. Return to the app and check activation. Use Refresh membership & credits after a purchase.

Never share an activation code from somebody else’s device. Your ShapeForge account does not require your own OpenAI API key.

Membership, cancellation and credits

Your account shows current purchase and AI availability. When purchases are open, membership is US$10/month and optional AI credits are separate. After the three free AI requests, paid AI requires membership and a prepaid balance. A US$20 credit purchase adds US$20 to that balance; request costs vary with size. Cancel future renewals using Manage billing & cancellation. This control remains available when new purchases are paused. Paid access lasts through its paid-through date.

Cancellation alone does not request a refund. For billing errors, refund requests or lost access, email hello@urbyn.ca from your purchase account. Include the receipt reference and app version; never send card numbers, passwords or API keys.

If AI pauses or a request fails

The free local assistant keeps working. Cloud AI requires an activated account, service availability and an eligible trial request or paid membership with credits. No automatic top-ups are made. Confirmed token usage may cost credits even when geometry fails or you cancel a generated plan.

If usage is marked pending or being checked, refresh your balance before retrying. An unknown provider cost stays reserved until reviewed; a timeout does not mean the request was free. Global spending limits can temporarily pause cloud AI.
