Roads & Trenches

The Roads & Trenches dialog displays a list of the roads in the current job, and the plot of the selected road in the horizontal and vertical planes.

The icon brings up the pop-up menu of additional options. More...

Note: When editing or deleting a road or its element (horizontal/vertical alignment, X-section/template/X-section set), you may get a message that the respective object "is read-only and cannot be edited". This happens if you are working with a job that was originally created in Kantoku 3D software and had road/road elements imported from RSM XML format.

RSM stands for Road Shape Management.
