Taxiways & aprons

Press T to open the Taxiway tool, then click along your intended path to drop points. Ends snap to runways and to other taxiways, so connections line up without pixel-hunting - hold Shift to bypass the snap, or Ctrl to lock the segment angle. Finish with a double-click or Enter; a taxiway needs at least two points.

To edit later, select the taxiway and drag its node handles. Alt-click a node to delete it.

• Surface swatch - pick the pavement. Dirt and grass are the free tier; sealed surfaces need a material unlock.
• Width - slider from 4 to 30 m, default 12 m.
• Corner radius - slider from 0 to 60 m, default 20 m. This rounds every bend into a smooth fillet; set it to 0 for sharp corners.
• Yellow centerline - checkbox for the painted guide line.

Every taxiway has an ATC designation field - a short name like A or B1. It does more than label the map: the designation drives the automatic hold-short sign labels, so a taxiway named A gets signs that read like the real thing. See Ground navigation for signs, hold-shorts, and the rest of the operational layer.

Press A to open the Apron tool and pick a preset card - each combines a surface and a marking style. Then click each corner of the area you want to pave. Close the shape by clicking the first corner again, double-clicking, or pressing Enter; an apron needs at least three corners.

Editing aprons

Select an apron and drag its corner handles to reshape it. Alt-click removes a corner, and the surface swatch swaps the pavement, same as everywhere else.

Pavement between runways is deliberately cheaper than the runways themselves: taxiway area costs 60% of the runway rate for the same surface, and apron area costs 40%. On the free tier you get 7,000 m² of grass taxiway and 9,000 m² of grass apron before anything hits the cart - details in Surface materials.
