The Align shapes to terrain tool aligns shapes to arbitrary terrains (map layers with attribute "elevation" defined) or to the y=0 level. All currently selected shapes and all shapes of the selected layers are aligned. The shapes are aligned to a terrain, using an alignment function and an optional offset. You can access the Align shapes to terrain tool the following ways:
- Click the Align shapes to terrain tool in the toolbar.
- Click Shapes > Align shapes to terrain... in the main menu.
The following parameters control the alignment:
The alignment function to apply to the vertices of the shape polygons.
The terrain to align the shapes. All attribute layers with an "elevation" attribute plus the y=0 level are listed here.
The offset to add after alignment to the y-coordinate of the shape points.
