Link Topography - No usable surfaces

[gerhard.p]

Hello Dynamo Friends

Spent my day trying to link a surface to Revit but keep getting this error:

Seems to be a known issue:

"The topography does not contain usable surfaces." appears when linking...

Tried to export landXML and import it back to civil, it did not help.

Is there anything I can do? Maybe not a dynamo question, sorry, but maybe it is?

Really appreciate any advice! Thanks and kind regards!

Solved by importing DWG and create topology from import.

Hi @gerhard.p if you want automate that you could try BriMohareb package have some great nodes

But you will need civil open as well when run
