FAQ

Is it free?

Yes. Everything in Circuit Builder today is free to use, and creating an account only takes an email address and a password — no card. Paid features may show up down the line, but nothing here now is held back behind one.

Do I need an account?

Yes — the editor sits behind sign-in, and signing up is the same email-and-password form as anywhere else. Once you’re in, your circuits are yours to take with you: export any of them to a file whenever you want. See Saving & Circuits for how saving actually works day to day.

Which scales does it cover?

Ten: 1/76, 1/64, 1/43, 1/32, 1/28, 1/24, 1/18, 1/10, 1/8, and 1/5. None of them are one set of numbers stretched or shrunk to fit — each scale carries its own lane widths, turn radii, and climb limits, derived from that scale’s own reference car. Scale & Units covers where those numbers come from and how to switch a circuit’s scale later.

Is it only for drift?

No — it’s built around drift, but it works just as well for a grip track. Every piece’s entry and exit width is its own setting, so a grip layout gets grip dimensions rather than inheriting anything from drift defaults.

Can I really print it and build it?

Yes, with one thing worth knowing going in: what prints is the plan, not the 3D view. Circuit Builder exports line art at true scale, split into tiles you print, tape together, and lay on the floor to build against. See Export & Printing for tile sizing and assembly.

Can I plan for a space I already have?

Yes — that’s the order Circuit Builder expects. Set your area first (a table, a garage floor, a hall), then draw inside it at the scale you’re actually building at. See Area Setup for how to define that space and what happens when a layout strays outside it.

Will my circuit look like this?

The road — its markings and its dimensions — is drawn to scale, and that’s the part you’re planning. Terrain and scenery around it are stand-ins for context, not a preview of what you’ll end up with. What your circuit actually looks like on the table is up to you and what you put around it.

Are my circuits private?

Private by default. A circuit stays visible to nobody but you until you publish it to the gallery, where anyone can see it and a signed-in visitor can remix it into a circuit of their own. Unpublishing takes it straight back down. Rating and favoriting need an account too, and neither exposes who rated or favorited what. See Community & Gallery for publishing and remixing in full.

Does it work offline?

Yes. Circuit Builder keeps a copy of your circuits on your own device as well as in your account, so the editor keeps working without a connection and pushes anything you changed up to your account once it’s back. See Saving & Circuits for how saving and syncing work together.
