Click the Truss icon with the left mouse button in the ribbon menu.
The trusses toolbar will open.
Move the mouse cursor over the column. When the cursor changes shape, click the left mouse button.
After you have determined the first point of the truss, put the cursor on the second column and create your second point. The program will create truss.
The settings of the truss drawn will be the current settings in the truss settings. Truss settings can be changed before the truss drawing or after the truss is drawn. In order to adjust the truss properties before drawing the truss, click Settings on the toolbar, and make the truss drawing after making the necessary changes in the opened truss settings dialog.
In order to change the properties of a drawn truss later, the relevant truss should be selected and click the Change/Object Properties button to enter the truss settings. In this case, the changes made in the truss settings will only be valid for the selected truss or trusses.
