Editing the Shape of a Split Region or Excavation

If you wish to edit the shape of a region or an excavation, first delete the region split or excavation so that the edge lines you sketched remain in the 2D drawing. Then edit the edge lines, for example by moving the points on the line. You can then add the region or excavation again.

Alternatively, you can define constraints for the edge lines. You will not need to delete the region or the excavation before defining the constraints. You can edit the shape of a region split or an excavation using the constraints. The changes are displayed in the 3D model when you update the terrain.

The following example demonstrates editing a split region (A) by moving the edge line points and the editing of an excavation (B) using a Distance constraint.

Editing by moving line points

1. First delete the region split. Select Terrain > Delete Region Split.
2. You will be prompted: "Explode lines of region split into 2D geometry?" Select Yes to have the edge line remain in the 2D drawing.
3. Move the points of the edge line, for example by their grip points.

   

4. Add the region again. Select Terrain > Add Region Split.
5. Select the edge line and the Confirm function.
6. Select a material for the region surface to be used in OpenGL shading and model visualization in the Add Region Split dialog box. Confirm by clicking OK.

   

Editing with a constraint

1. Add a Distance constraint to the drawing. Select Constraints > Distance.
2. Select lines (1) and (2) and select a position for the dimension (3).

   

3. Double-click the dimension and enter a new dimension in the Properties dialog box. Confirm by clicking OK.

   

4. Select Terrain > Update Terrain. The terrain's 3D model is updated.
