Export to AutoCAD missing data

[dpollard909366]

Has anyone had problems with losing some geomoetry and data when exporting Revit Views to AutoCAD?

It seems very strange and random. Each time I export, it seems to delete different groups from the dwg. No real consistency to what it leaves out of the export.....

We have a file which consistantly leaves out the foundation walls on export.

I've found that it's a topo issue. Walls intersecting with topography get removed on export to AutoCAD.

Another serious problem, Buildings without foundation!

That's what our structural engineer said when we sent him backgrounds without foundation walls! Turning off the topo works just fine.
