Note that for HEC-2, there are two ways to generate output report tables. One way is to define them using the J2 card, which is what it seems you are doing. This only generates tables when you run HEC-2 and the results are in the output report.
The other way is to use the Scenario Analyzer, which is available from the RiverCAD Output Menu. Select Output | Profile Tables. It will display the output results for both HEC-2 and HEC-RAS. However, if your model did not run successfully or you used a long directory path or an AutoCAD drawing name with a space in it, there might be some small problem in finding the results. That might be the issue where it cannot find the analysis results.
From the Scenario Analyzer, you can define your own "custom" profile tables by selecting whatever variables are available for HEC-2 and HEC-RAS.
If you continue to have problems, please call our technical support staff at 1-800-488-4775 and they can review your problem via an online Internet session.
