Road 3D has the following applications:
Subprogram Check
Subprogram Check Slope
Subprogram Setout
Subprogram Slope Setout
1. Create or upload road alignments.
2. Select horizontal and/or vertical alignment files.
3. Define setout/check/slope parameter.
4. Select one of the Road 3D applications.
The alignments must be continuous because geometrical gaps and chainage equations are
not supported.
The file name for the horizontal alignment file must have the prefix ALN, for example,
ALN_HZ_Axis_01.gsi. The file name for the vertical alignment files must have the prefix
PRF, for example PRF_VT_Axis_01.gsi. File names can be 16 characters long.
The uploaded or created road alignments are permanent and stored even if the program is
closed.
Road alignments can be deleted onboard or via GGO Data Exchange Manager.
11.13.2 Basic Terms
Road projects consist, in general, of a horizontal and a vertical alignment.
Any project point P1 has E, N and Z coordinates in a deter-
mined coordinate system and has three positions.
