Click anywhere on the plan to add an intersection point, and drag an existing one to move it. Each IP carries a radius and a curve type, so the alignment rounds smoothly through it with a circular arc or a Bezier curve instead of kinking.
▪
Because chainage, profile, templates and earthwork are all derived from the live alignment, moving an IP after the rest of the design exists is safe -- everything downstream updates rather than going stale.
▪
The plan can be switched between Relief, Contour, Hybrid, GeoMap and Aerial rendering. GeoMap and Aerial fetch online map tiles and need an internet connection; the other three work entirely offline.
▪
The window also carries the polygon tool for footprint-based earthworks -- a building pad, a lagoon or a laydown area -- described by a boundary rather than a centreline.
▪
The first render takes some time, since the terrain has to be built; the delay occurs only once.
