Quickstart — draw your first lane in the browser

drawtonomy has two five-minute paths, and they are two ends of one pipeline. Draw the scene to get a figure you can export; make it move to turn that same scene into a running scenario with a PASS / FAIL verdict. Start with the drawing track below — the scenario track picks up exactly where it leaves off.

Your first drawing (5 minutes)

Section titled “Your first drawing (5 minutes)”

Blank canvas to an exported scene. No install.

1. Open the app

Section titled “1. Open the app”

Go to drawtonomy.com. Everything runs in the browser; nothing is uploaded.

2. Draw a lane

Section titled “2. Draw a lane”
  1. Press N, or click the Lane tool in the toolbar.
  2. Click on the canvas to place the start of the centerline, click again for the next vertex, and press Enter to finish.
  3. The left and right boundaries appear automatically.

3. Place a vehicle

Section titled “3. Place a vehicle”
  1. Press P to open the Participants tool.
  2. Pick a vehicle icon (hover to see its name) and click on the lane you just drew. The vehicle turns to face the lane’s direction of travel by itself.
  3. To turn it around or fine-tune the heading, select it with V and drag the rotation handle — the dot above the selection box. Drag a corner handle to resize.

4. Export the scene

Section titled “4. Export the scene”

Open the export menu and pick a format:

  • .drawtonomy.svg (drawtonomy’s native SVG format) — the default to reach for. A regular SVG file that previews in browsers, GitHub, slide decks, and Markdown out of the box, and reopens in drawtonomy with every connection, shared point, and overlap relationship intact. Save your scene as .drawtonomy.svg even if you only need a flat image today — your future self (or a teammate) will thank you when the scene needs an edit.
  • PNG / SVG (flat) / JPG / PDF / EPS — pick one of these only when you specifically need a flat, non-re-editable image.
  • Export for esmini — a zip with OpenDRIVE + OpenSCENARIO ready to play in esmini.

Export your scene covers the formats in detail.

Your first running scenario (5 minutes)

Section titled “Your first running scenario (5 minutes)”

The scene you just drew is also the road and the actor for a scenario. Turn it into a run that ends with a PASS verdict:

  1. Switch to Scenario mode. Open the hamburger menu at the top left and, under EDITING, click Scenario. The drawing toolbar shrinks and the LOGIC card docks to the bottom.

  2. Make sure you have an actor. If you placed a vehicle above it is already there; otherwise click Add actor and click a lane.

  3. Add a phase. Click + Phase. drawtonomy creates a phase, a first event, a default Change Speed action, and a default trigger — all in one click.

  4. Play. Press the ▶ button on the left of the LOGIC card. The verdict badge goes IDLE → RUN → PASS.

  5. Export or share. Hamburger → Export → OpenSCENARIO (.xosc)… for the scenario and .xodr for the road, or record the run with Export video….
