When you create a Portal Frame, the column size proposed by default is a HEA200 and the rafter is a IPE200.
In order to modify e.g. the "Column size", you need to go to the Management Tools ("Start the Management Tools" icon from the "Standard" toolbar), go to "Default sections" category and search for the "Default section for structural element (Column)" default.
If you want to define a IPE360 (instead of the HEA200), just change
"HEA nach DIN#@§@#HEA200" by "IPE nach DIN#@§@#IPE360".
Remark: the default for the rafter size is "Default section for structural element (Tie Beam)"
Then press" Load settings in Advance" to save the changes and go back to Advance Steel.
Next time you will create a Portal Frame, the proposed "Column size" will be IPE360 as defined.
