2. Select the terrain model which you would be using for your entire design. (point to consider – dense triangulated, covering the area, no bad spots, etc.) with any one of the methods above to clear unwanted triangles, zero elevations points.

3. Export the terrain model to DTM, TIN, Land XML formats and save these in the Terrain folder of the data set.

4. Create a new 3D DGN and import the TIN, DTM XML from above.
