The Portals Toolbar

You can show further graphical displays on your frame of the snow loading and the purlins/cladding rails.

Select the snow icon to display the snow loading on the frame. There are 3 separate snow conditions used in the analysis.

From the droplist select L0 for uniform snow over the whole roof, L2 for snow on one side only of the roof and L3 for the valley snow drift condition (shown below).

Select the purlin icon 'Z' to display these on the frame. The approximate purlin shape to be used can be defined on the 3D Bays tab.
