Chief Architect Premier


I have made a number of changes to the terrain in my plan, but the changes don't seem to apply. Why don't the changes that I made show in my plan?


In Chief Architect, you can add elevation data to a plan and then direct the program to generate contour lines and 3D terrain based on that data. The program does not generate these contour lines and terrain automatically, however, in order for changes that you make to the terrain to take effect, you must tell it to do so.

To build or rebuild terrain

  1. On Floor 1 of your plan, select Terrain> Create Terrain Perimeter from the menu.

    Note: Before terrain elevation data, terrain features, or terrain modifiers can be created, a terrain perimeter must be present. If the Create Terrain Perimeter option is not available, a terrain perimeter has already been created for this plan.

  2. Using the Terrain Elevation Tools and Terrain Modifier Tools , make any needed changes to your terrain.

    You can also import terrain elevation data from text or DXF/DWG files.

  3. Select Terrain> Build Terrain from the menu. Your terrain will be updated in both the 2D and 3D views.

You can also specify that terrain be rebuilt whenever you create a 3D view by selecting 3D> 3D View Defaults from the menu and checking the box beside Auto Rebuild Terrain under the Options panel.
