is it possible to get the alignment name which the corridor surface is built from when the surface is being data referenced. in other word no corridor as the middleman.
the way i see it is when corridor suface is referenced, it becomes a regular surface and loses some properties such as parent alignment.
i am still using COM. maybe .net can do it? either way works. so just please someone knows the code that would be very helpful. thank you.

Did you try with IsReferenceObject or IsReferenceSubObject ?
If this doesn't help, could you upload a sample DWG file for me to check if this is possible with current set of APIs.
