JoshPlum, thank you but in fact, it is not popular to use Risa3D for high-rise building but you made me to come up with an idea.
I am going to find someone who has a RISA3D and ask him to define a plenty of HSS shapes for making a data base.

Hi
I am dealing with the design of a high-rise building with heavy hollow steel section(built-up column by plates), my question is, is it possible to design the base plate with such a heavy box into RisaBase? It seems that RisaBase is able to read just standard steel profiles not user defined...
