Hello,
I have the following problem. I created in HEC-GeoRas (V4) the required layers:
1. Stream Centerline
2. XS Cut Lines
I use a TIN as a DTM. It is no problem to create the required attributes (topology, lenghts/stations, elevation) for the stream centerline. Likewise no erros appear when I create the attributes (river/reach names, stations) for the XS Cut Lines layer.
But when I want to convert the XS Cut Line Layer from 2D to 3D, then the attribute table still remains empty. A message box appears with no text. This makes it difficult to find the error.
I know for sure that the cross section do not intersect and do not overshoot the baunds ot the TIN.
Does anybody has an idea?
Thank you very much in advance.
