C2 out w/bent pipe

I am trying to export a C2 file for our engineer to analyze in Caesar (ver. 5.10). The pipe model consists of valves, straight runs of pipe, and some bent pipe. When the C2 file is opened in Ceasar, all of the components of the model are showing up...except for the pieces of bent pipe. I was just wondering if I am missing a step, or if we need to adjust a setting in CadWorx or Caesar to make this work.

Can you send the following files to cadworx@intergraph.com so that we can look into this issue?

- For issues with CADWorx Plant to CAESAR II interface, email the AutoCAD model drawing (DWG) file and CAESAR II input file (*._A, *.C2). Also, run the CADWorx command GETALLSPECDATAFILES. This command will copy all specifications and data files used in the model into sub-directories under where the model drawing file is located. Zip the contents of these directories and email it to us. If the model consists of several line numbers, please indicate in the email which line number(s) you are having issues with.
