I am trying to create physical members in STAAD steel design, which works for most of the members I wish to create. However, when I try and combine some members into a physical member I get the following error message open in a window:
'Selected beams are not aligned to the same direction or in other words their local axis are not parallel and of same sense. Unable to form physical member.'
Others give the message 'Beams are not having same property. Unable to form Physical Member.'
As far as I can tell the first members are aligned, and the second type have the same properties. Can you give any guidance on what I should be doing to avoid these messages?
A quick response much appreciated!
