how to calculate End Are Volume with topsoil

Hi Sigfus, yes it's possible, you need to create a surface template that have mesh properties to be unsuitable then assign this surface template to your surface "topsoil".  The trick is to have this surface to follow your corridor limits.  Once you run the create cut and fill volume it will create the different volumes like it suppose to be.  I haven't verify that the EAV reports are reading evrything right, but it should work also.

Hope it helps

Or you create an overlay component in your template that you asign a mesh proprties of unsuitable, it works also

I like the Surface template method , its easy to use. 

Yeah, and I did verify meanwhile and the report or working good, same as Inroads

I did use the plan civil named boundary as a extern boundary to the surface template. 
The named boundary reach 15m from the corridor centerline, covering all the corridor.

Are topsoil volume from the boundaries area or just inside the corridor area
