Is there a way to update/change a DEM file or some kind of elevation layer which I could use as a terrain? Basically, I have a DEM which has current elevation and I have a 3d multipatch polygon which represents a road that will be built. The road construction will change the landscape which is represented in the multipatch polygon. I need the elevation of the multipatch to be represented in the terrain as well as the surrounding areas current elevation. I hope that makes sense.
I included a picture and you can see where the road is intersected by the terrain. Thanks for the help.
