Suppose you wish to design a column next to the already calculated beams within the active project. First add a new computational model to the active project using the icon 
in the toolbar. In the new window that appears, then you draw a vertical rod with a length of 3.5 meters and define the supports as shown in the figure below:
Add a dead load of 10kN and a life load of 10kN in point 2.
Suppose you want to construct this column with a steel tube profile, then you determine the most optimal section within the profile class B:
1•2•Build solution will give you following proposal:
In particular a profile tube with a diameter of 48,3mm and a thickness of 6,3mm. This solution meets all requirements for resistance of the sections and the buckling stability of the column. If desirable, this can be check with the graphs 
and 
.
Note that the maximum deflection is L/∞ amounts. This deflection has no physical meaning.
If you want to calculate the same column in reinforced concrete, than 1•2•Build will propose reinforcement that meets all standard requirements (thereby opted for a section with a fixed width and height of 200mm):
