2D or 3D Contours

Spatial Manager™ for GstarCAD allows you to generate both minor and major contour lines in 2D or 3D formats.

Contour altitudes can be labeled automatically, and contours can be organized into separate layers with distinct color schemes for clear visualization.

Additionally, optional attached data tables can store contour elevation values.
