Deleting a Region Split

You can delete a road or yard area added to a terrain as follows.

1. Select Terrain > Delete Region Split. If you selected the function with the model window active, the program will automatically activate the drawing window.
2. If there are several region splits in the terrain, select the region by clicking its split line. If there is only one region split in the terrain, the program will automatically select it.
3. You will receive the prompt: "Explode lines of region split into 2D geometry?" Select either of the following:
   • Yes - When you wish to retain the polyline defining the region's edge line in the 2D drawing. You can, for example, edit the polyline points and add the region split again.
   • No - When you also wish to delete the polyline from the 2D drawing.

Note

• You can delete the region and retain the polyline also as follows:
  1. Select the region in the 2D drawing.
  2. Right-click to open the context-sensitive menu.
  3. Select Advanced > Explode into Geometry. You will receive the prompt: "Are you sure you want to explode?""
  4. Select Yes. The region will be deleted from the terrain model, but the polyline will remain in the 2D drawing.
• If you delete the region by pressing the Delete key, the polyline will also be deleted from the 2D drawing.
