1. Automatic slope hatching

Pick a top line (crest) and a bottom line (toe), and slope ticks are generated between them at the spacing you choose, to survey accuracy.

2. Works with the geometry you already have

Lines, polylines, 3D polylines, arcs, splines and ellipses, in both 2D and 3D.

3. Cut and fill detection

Cut, fill and generic sections are detected automatically and drawn with their own colours and layers. ByLayer is supported, with an explicit override when you want to restyle a layer deliberately.

4. Background mask that follows the real geometry

An optional background hatch follows the actual vertices of your lines, so corners stay sharp and curves stay curved.

5. Interactive corner adjustment

Where slope lines naturally converge at an inside corner, drag the on-screen preview to spread them exactly as you want them. Your adjustment always takes priority over the automatic rule.

6. Live preview

The preview in the settings window is produced by the same engine that draws the final geometry, so what you see is exactly what is drawn.

7. Built for production drawings

Draw along an entire alignment or a picked chainage range, keep drawing in a loop until you press Escape, undo slope by slope, and work in metric or imperial units.

8. Free

No licence key, no activation and no time limit.
