The x,y,z, coordinate points are imported and a triangulated surface and corresponding contours are generated and saved in a Terrain file. Sometime later, after rock has been removed from the quarry another survey is done and again imported, triangulated and saved in a second Terrain file. This is done using the Edit - Calculate Volumes function. It is now possible to create and modify features in the Terrain Profile window. This powerful function allows you to create any type of surface or sub-surface alignment, geological zone or excavation.
Profile design is useful for a variety of applications.
A topographic survey of the existing road is done and the coordinate points are imported into the Terrain module. A triangulated surface and corresponding contours are created. Using the mouse on the screen cross sections are drawn in plan window. In the Profile Window each cross section is viewed. Using the side slopes outside the road prism as a guide, the original ground line is drawn.
