I created a surface and a stream centerline alignment and ran cross sections to prepare to export to HEC-RAS.
I go to Output tab / Export panel / Export to HEC_RAS / and in the table It shows my surface (EG2) and
Site but when I click the alignment down arrow and it shows only "NONE". I selected the greem box to pick my
alignment and it apeared to pick it but it does'nt show my alignment called "CL CREEK" in the dialog box.
And it is similar to my cross section options. I went ahead and tried to export it but my GEO file has zero bytes
Thanks John Wilson
Solved! Go to Solution.
I suggest you search the news group on the topic. There are several posts about problems with this tool. I personally decided not to invest time trying to work through the problems.
Did you try playing with the Site dropdown. The Alignment may have been put in a Site that you didn't expect?
Yes, make sure you look under <None> also there.
Many times Alignments are not placed under any Sites, so they don't interact with other objects.
Anybody knows how can I export a designed work (let's say a designed surface) for Hec-RAS (.geo format) Is it possible to do it or not, and if it is what are the steps?
I know how to export an EG to hec-ras!
OK, that's easy, but doesen't work. I mean, it doesent work to me, maybe I do some mistakes, I don't know. Tell me how you do it! Do you make form a coridor a new surface and then you export it to hec-ras or what?
Thank you for response
I am facing a problem while exporting CIvil 3d data to HEC RAS. First i created a surface by using the Google Earthextension. I defined the alignment. I defined the section lines. Under Export to HEC RAS tab i selected the surface, alignment & section line group. Initially after creating the .gro file and later importing it to HEC RAS i could clearly see the data as in the Civil 3d viewport. Now when i try to import HEC RAS shows an error saying that some of the sections are beyond reach extends. it also offers to remove georeferncing but if i do that the alignment is just a straight line with the cross sections. Moreover the direction is also flipped.
Also i wish to know how can one import an entire river network to HEC RAS.
I am working on the finished surface created from the corridor. When I tried to export to HEC-Ras, it doesn't have any points in it. How can I do this? I already made another sample lines just for the finished surface, still it didn't work? I hope smebody can reply on query.
