GeoRAS does not export river stream profile when using Tile option

[TimHaeusler]

I am using GeoRAS 4.3.93 with ArcGIS 9.3.1.  I have set up streams, xscutlines etc. and am using the tile option to get data from 50 odd TIN models.  Everything appears to work correctly, except it appears the converting stream to 3D is not implemented yet for the tile option. When I try to export the data to the RAS import file, no stream data is exported.  I am using the "new" export method because the old export method does not do anything.  I have a little over 1500 xsections and am getting data from detailed TINS produced from LiDAR data.  I suspect i am not getting the stream data because either 1. it is looking for a 3D stream file (which I don't have) and does not work with a 2D file, or 2. am running into some unreported memory problems in the export process.  I can not open the full xml file due to memory problems. When I try to load the sdf file generated by GeoRAS, RAS falls over with an error message and all I can see from opening the rasimport.sdf file in notepad, is that the stream data is missing, all other data is there. Can anyone else shed any light on this?  I have been using the GeoRAS process with single TINS for years with few problems so I suspect something to do with the tile option.

Thanks

I solved the problem and as you connot delete posts in this forum I will run through it just in case someone else comes across the same problem.  If you don't know that the creation of a 3D stream layer is not possible when using the tile option, and you try and do it, you get an error message saying it is not implemented yet,   BUT it still creates an empty 3D file of your stream and puts this empty file in your layer setup under "Stream Profile" in the optional layers section - you need to change this back to "null" before you try and export.  If you do not it does not export any stream data, 2D or otherwise.

Now if I could only solve why I now run out of memory during the "new" export process whilst it is creating the RAS XML file... and why the "classic" export process does not work at all!
