Exporting to HEC RAS straight line without xs.

[Anonymous]

I'm trying to export and stream profile and cross sections to Hec Ras.  The "import GIS data" works just fine but then I only see a straight line showing the streams profile and there are no cross sections.  When I go to edit the cross sections all the data is there just not showing up.  

All my xs's are within the surface boundries

the alignment is within the surface boundries

I'm running my stationing from downstream to upstream.

My survey/data isn't the greatest, it was done by a intern.  

I'll attach the Autocad File.

Hi!

I think, the problem is, that some points of the alignment are exactly on the surface boundries.

For example Point 80073, station 10+59,91.

And you can see all cross sections in hec ras when you zoom in. You also see the stream in Hec ras and it fails hat Point 80073.

I created some manual points and it worked! Thanks!

Did you import the file to hec ras correctly?

You must open or start a new project in ras,  Edit menu, edit geometric data, in the Geometric data dialog, file menu choose import geometry data and then GIS data.
