Learn Circuit Builder: tools, course elements, scale and units, exporting, saving, and the public gallery.

Start

  • Getting Started — Create your first circuit and find your way around the canvas, the elements panel, and the Plan/3D toggle.

Building

  • Tools — The tool rail — Select, Road, and Elevation — and how to draw a lap.
  • Course Elements — What’s in the elements panel for Competition, Touge, and City courses: markings, objects, zones, pit, rest stop, and parking.
  • Area Setup — Draw the table, garage, or hall your course has to fit inside, and let Auto Fix square up anything that strays outside it.

Scale & Terrain

  • Scale & Units — The RC scales Circuit Builder supports, how lane widths change with scale, and switching between feet and meters.
  • Elevation & Structures — Raising the road, the piers and decks that appear automatically, and running a course under a tunnel.
  • Scale Calculator — Convert a real-world width to its model-scale equivalent, or a space on your table back to real-world feet, at any of the ten RC scales.

Visualize

  • 3D Viewer — Fly around your course in 3D, chase a car around the lap, or ride along in the driver’s seat.
  • Simulation — Tune how a car drifts through a corner and line up several cars to check they don’t collide.

Share & Save

  • Export & Printing — Print a course to scale, export tile templates, or save a circuit file to back up or move between accounts.
  • Saving & Circuits — How circuits are saved, synced across devices, and organized in My Circuits.
  • Community & Gallery — Publish a circuit to the public gallery, rate and remix other people’s courses, or embed one on your own site.

Reference

  • Keyboard Shortcuts — Every keyboard shortcut and gesture in Circuit Builder, tool by tool.
  • FAQ — Answers to common questions about Circuit Builder.
  • Drift Terminology — What apex, clip, manji, and touge actually mean, and how Circuit Builder’s Simulation panel lets you tune each one.
  • Other Ways to Lay Out a Track — How Circuit Builder compares to graph paper, general CAD tools, and other RC track-layout software — what each is actually good for.
