Terrain View

3D View

The terrain view is the central window of the program. This view can be a top view or to be a spatial representation.
The 3D view will usually be the basis for working with the program.
The top view serves mainly to place additional buildings.

Top View

Additional tools of the top view

Edit Buildings

With a click on a house this can be selected. This is acknowledged by a frame with click marks. The lines through the marker points indicate in which direction the house can be modified. When dragging in such a direction, a window will appear showing the current outline data of the house. The data must be saved by pressing SAVE. The data can be changed manually before. The action is canceled by pressing Cancel or clicking in the void.
