Area measurements in the Model view via Shapes

[Thomas_Steffen]

Hello,

i know that i can calculate areas via shapes in my DEM or orthophoto. But often, this is not enought. Today i had to calculate the wall- and roof-areas of a building (church) for a client.
The problem with the current method is, that every time i select unwanted polygons for erasing, the polygons behind are selected too. Then i have to rotate my model and deselect the polygons i want to keep in the model.
If it is not possible to implement the polygonal measurement feature for the Model view, it would be great to implement a selecting method, that only selects the polygons that can currently be seen and doesen't select all polygons behind.

Best regards
Thomas
