MOTORSPORT CIRCUIT DEFINITION

Build the circuit,
not just the trace.

Import a GPX trace, correct the geometry, place start/finish, set race direction, create sectors and mark precise corner entry and exit boundaries—all against real map or satellite imagery.

THE WORKFLOW

Raw GPS becomes a structured lap.

  1. 01 / IMPORT

    Start with the trace

    Open an existing GPX track or establish the circuit from GPS coordinates.

  2. 02 / REFINE

    Correct the geometry

    Align the line to real-world mapping and shape difficult sections with node and curve tools.

  3. 03 / DEFINE

    Give the lap structure

    Add direction, start/finish, sectors and corner boundaries in their proper order.

PRECISION GEOMETRY

Shape the circuit, not just the GPS trace.

Recorded points rarely reproduce every bend cleanly. Edit individual nodes or reshape a section using 2-point and 3-point tools, Bézier curves and handle-based control. Radius and tension create a smooth, deliberate line that follows the circuit instead of accepting GPS noise.

CORNER DEFINITION

Define corners the way drivers experience them.

A corner is more than a point near an apex. Set a precise ENTRY and EXIT along the circuit so the full driven section is explicit and remains tied to the trace.

COMPLEX SEQUENCES

Handle linked corners properly.

Compound bends, switchbacks and linked sequences do not have to become one generic corner. Separate numbered entry and exit boundaries preserve each element, even where one corner flows directly into the next.

SECTOR STRUCTURE

Break the lap into meaningful sectors.

Create an ordered, continuous sequence around the lap. Position or resize each boundary, inspect exact start and end positions and calculated length, then close the sector loop.

START / FINISH

Anchor the lap correctly.

Place the gate across the circuit or locate it from GPS coordinates. Set clockwise or counter-clockwise direction so every definition follows one lap order.

VISUAL VERIFICATION

Check it against the real circuit.

Switch between satellite, street-map and blank views, rotate the map or reset north, and navigate to pasted coordinates. Edit in geographic context, never blind.
