Dear Manik,
Caesar does not give you restraint reports in local coordinates for the reasons expalined by Richard.
However your problem can be solved by rotating your model. Rotate the model so that the segment of piping which was not aligned with Global coordinates is now aligned. Check the restraint report for the concerned nodes. You may decide to rotate in such a manner that your pipe axis becomes X axis.
If you have various segments which are not aligned with Global coordinates you may have to do this rotation exercise several times. But that should not take much time.

Regards
Siv
