Import SDF file created by HEC-RAS

[jbbarrus]

I am trying to import an SDF file that was created by HEC-RAS 4.0. I have tried Map > Tools > Import, and I have tried File menu > Create DWG From > Autodesk SDF 2 (MapGuide 6.x). Both ways I get an error telling me that I don't have an SDF file or that it is improperly formatted.

Can anyone tell me how to import an SDF file that has been exported from HEC-RAS?

Any help would be greatly appreciated.

The HEC-RAS SDF format is not the same format that Map3D uses. The HEC-RAS format is an ANSI text file that you can open in Notepad if you want, where as the Autodesk SDF format is more of an SQlite format. IOW to use an HEC-RAS file/info you need one of the extensions for Civil3D if you want it in AutoCAD.

Ok. That makes sense. I used the HEC-RAS import extension and it worked ok. Thanks.

Hello!

I' have a problem. I coldn't import sdf file into civil 3d by hec-ras export/import extention because an error always come up "run-time error '62' Input past end of file.
What can I do?

You need to ask the Civil 3D group, http://forums.augi.com/forumdisplay.php?f=99
It's not a Map 3D issue.
