Figure 1. Road Tools Selection Menu


The Road option provides a way to create a surface graphic for the various Altair Road Files.

From the dialog, select the desired road file. All the road types mentioned in the previous sections except 3D Cleat can be visualized. The crg files must be chosen directly instead of providing the rdf containing the crg.
Figure 2. Road Dialog


In the Road Tools dialog, the Road File path and the Road type must be chosen as shown in the figure below.
Figure 3. Road File Path and Type Selection

The MDL option allows the selection of the file path location where the created road graphics are saved.

Road Sampling can be changed as per your requirement to reduce the time and detail level for producing graphics.

If the [GRAPHICS] block is described in road file, it will be used for the road graphics definition.

In the case of a FLAT road type, a checkered grid is created. The grid size is obtained from the LENGTH and WIDTH value available in [GRAPHICS] block. The square size is obtained from the ROAD_INCR value.

$-------------GRAPHICS
[GRAPHICS]
LENGTH = 160000.0
WIDTH = 80000.0
ROAD_INCR = 500
The road’s origin is shown by the marker in the figure below. If the ROAD_INCR is positive, the grid is created in positive x direction. If negative, the grid is created in negative x direction.
