Assign selection polygons

Assign selection polygons command creates Selection shapes from selected polygons drawn in the CAD file.

This is useful if you have polygons of buildings or building roofs. If they are assigned as Selection shapes, the area designated by one polygon is rectified from a single raw image if possible.

To assign selection polygons:

1. Draw and select polygon(s) with CAD platform tools.

2. Select Assign selection polygons from the Image pulldown menu.

This opens the Assign Polygons dialog:

assign_polygons

3. Select settings and click OK.

This assigns the image to each selected polygon which best covers the area of the polygon.

If Force symbology settings are switched on in Selection shapes of the TerraPhoto Settings, it also creates a copy of the original polygon(s) on the CAD file level that is defined for storing Selection shapes.

4. Update the view using the CAD platform tool to make changes visible.
