I used the "Create from File" tool and loaded up a .dtm file to create a terrain model with Inroads SS4. I used the feature definition Existing_Boundary. After the terrain model is generated, I see the boundary as well as all the features drawn in on the Default level. I have all the toggels set to OFF for displaying breaklines, contours, triangles, etc; however, I not sure why these features are showing up. I can turn off the Default level to make them go away, but my file is extremely slow and I think it's because of all these feature lines.
Is there something weird going on with my DTM or am I missing something when importing the terrain model? I've created them before and usually all I see is the boundary with the option to turn on features, contours, etc.
Thanks!
