Hi all, This may be a weird request, but I have to ask. Having imported survey dwg, with good terrain elevation data, I want to adjust the terrain by adding my own final grade elevation data. I was hoping to keep the original survey data as a kind of before and after reference. I know we can turn off the display of these lines, but I'm looking for a way to disable line by line, region by region, etc.
Maybe as a sort of options set of terrain/landscape possibilities, all in the same plan, perhaps just on different views/layer sets ?
Has anyone else wanted to do this, or am I just not seeing the correct approach to get this affect?
Thanks very much,
Greg
