This command draws a horizontal alignment in MDT format that is stored in a file generated by the Alignments > Export Alignment command. In order to import horizontal alignments in other formats, simply select the appropriate format from the list of extensions in the file browser that is displayed when you run the command.
Although the horizontal alignments are drawn as polylines, all their analytical information is associated. Straight line or curved sections of the horizontal alignment are drawn with a single vertex, but clothoids are discretized by inserting a vertex at each distance specified by the Clothoid Distance parameter of the configuration menu’s Alignments section.
If one observes that curved sections are drawn as a traverse instead of as arches, the drawing should be regenerated with the CAD REGEN command.
If a horizontal alignment file is imported from a previous version of MDT, the program requests data on Category and Project Speed, as is done in the Alignments > Convert Polyline to Alignment command.
