RMC the Legend or select the Display Options button to show the Display Options and select 3D View | DEM Options as shown in Figure 1. If the user has a polyline P2D file or any comma or tab delimited X, Y, Z file then they should first create an overlay file from this with the Interpolate DEM from Polyline button. This interpolation process can be quite slow, but once the DEM is generated it loads quickly. The native DEM file is *.TB2 format and should be loaded with Browse button. The user must also select View from the DEM Option frame. Clicking OK will then display the background file as shown in Figure 2.
