Landxml Terrain Model data may be not in correct format.
this message pop up when i'm trying to insert landxml terrain model from Civil 3d 2018 64 bit to SeweGems 10.01.01.04 - 64 bitany solution?
I have found the reason for this issue after many attempts, that SewerGems not accepting any surface has modification by (Boundaries) option under the definition tab so i were have 2 options to solve:
1 .clean the surface from any edits in boundaries option then export as landxml.
2. extract 3D polylines from countours of the modified surface and copy it then open new civil 3d tab file and paste the 3D Polylines and convert it to Surface then Export it.
I hope this solve the problem with any one have it. Thanks
