I am trying to calculate the external surface area of a curved bridge form. I see in a post from 2012 is was possible to get the area of a particular material. Is it still possible to do this in SU 2015? as I cannot find the reference or dialogue to enable me to get it.

Is there a simple way to get this information.

Thanks in advance

I am wanting to model a large area of land about 10km square. I presume the only way to do this is to still stitch smaller grabbed pieces together?

Does anyone know how accurate the topography of GE is?

Is there a way to alter the topography in the GE view if an excavation is a part of the project?

Thanks in advance.
