Note that the current release of RiverCAD exports this as a single HEC-RAS model with multiple reaches. If you have defined your model correctly in RiverCAD so that it analyzes the entire model as a single model, then when you export it to HEC-RAS it will be the same.
You should check to make certain you have the latest RiverCAD. You can download this from here:

If you continue to have problems, please send me your RiverCAD drawing file to review.
