Example of a Subtraction Solid in the Terrain

In this example input consists of the following steps:

·      Draw a 2D contour for the cross-section of the construction pit and save it as a profile.

·      Switch to the ‘Environment’ layer.

·      Input a sweep solid as a closed polygon with the profile of the construction pit.

·      Convert the sweep solid to a subtraction solid.

·      Set the subtraction solid as invisible in the visibilities dialog.

The dialog for the sweep solid showing the profile of the construction pit:
