Correction of zero elevation

Correction of zero elevation

Ribbon: Topoplan – Relief > Correction of Zero Elevation
Menu: Ground – Elevation > Correction of Zero Elevation
Toolbar: Elevation > Correction of Zero Elevation
Command line: NG_ADJUST_ZERO_ELEVATIONS

The command changes the elevations (Z coordinate) of a 3D polyline, aligning them in the range from one valid elevation to another using the linear interpolation method.
When running the command, specify 3d polyline in the drawing and press Enter. The nodes the Z coordinates of which had 0 value, will be corrected.

NOTE: Zero values of Z coordinates of endpoints of 3d polylines will be corrected for non-zero values of Z coordinates of adjacent points.
