What it does
Surface and contours at once
A triangulated surface and contours are built the moment points load. Interval and smoothing are yours to set.
Draw an alignment, get a profile
Click along your route. The ground profile appears immediately.
Cross-sections on demand
Sections are cut at the interval and width you choose.
A DXF your CAD team can use
Points, 3D contours, surface faces, alignment with stationing, profile and section sheets, each on its own layer.
How it works
Three steps, start to finish.
Import points
Or an existing contour DXF.
Draw the alignment
Profile and sections follow.
Export DXF
Open it in AutoCAD or Civil 3D.
