I have a terrain model in a 3D dgn, how to extract contours into a 2D file?


  1. Create new 2D dgn
  2. Attach terrain dgn as a reference
  3. Use the merge to master command  How to Merge into Master  
  4. Use drop element command on the terrain graphics

**You might have to run step 4 more than once if you need to simplify the graphics into individual line strings.
