Ok, this is an issue that has been giving me an immense amount of trouble, I'll try to explain it the best I can...

I was given a set of topographic data comprised of polylines, the size and complexity of the file was such that it is impossible for me to import it into Revit and be able to edit (grade) the surface once I created a toposurface.

So... the solution I came up with that by all means should work was to make all the necessary grading changes in AutoCad before importing the file into Revit and creating the toposurface. This way once the toposurface is generated in Revit it will already have all of the grading and places for the building pads in place and all I would have to do is drop my buildings on top of it.

This is where I cannot figure out what is going wrong...I make the necessary grading changes in AutoCad and everything looks fine...but once I import the file into Revit and create the toposurface it gets all messed up...
To illustrate this I will include screen shots of both the AutoCad file and the Revit file.

Any help or suggestions on how to solve this issue would be greatly appriciated!
