In the above mentioned version of STAAD.Pro, section 9E.3 in the help menu says that "Member properties may also be specified using the User Table facility except for the General and Prismatic member". Why is it that "general and prismatic members" are excluded? Actually, it has been found that for general member since STAAD is unable to do section classification, this is the only way to do their design. PLease let me know whether I am wrong somewhere. Please Clarify.
