GGU-SLAB: "Distributed loads" menu item
Certain FEM elements can be assigned distributed loads by defining the area required as a polygon using 4 counter-clockwise points. You will then see the following dialog box:

When analysing with the new partial safety factors you will also see the "Live" check box because of the differentiation between permanent and changeable surcharges. If you activate the "Add distributed load" check box, the value entered will be added to any distributed loads already present. If negative entries are made the distributed load is reduced correspondingly. If you click the "Delete all" button, all existing distributed loads are deleted and you can define a new distributed load after specifying a new polygon.
