You could also add a closed shape element as a Void to the terrain model. A 'void' acts as an 'interior boundary' to trim triangulation from the terrain. You can use the Add Features command to add a VOID or a DRAPE VOID to the terrain. If you have a 3D element with elevations, you can use the VOID option. If you have a 2D graphic which you want to drape onto the elevations of the terrain and use it to clip out the triangulation of the area, you can use DRAPE VOID.
