Load combinations serve two purposes; they can be used as a filter in the Load Overview dialog box to display and select (or exclude) specific load types. A multiplication factor can be specified for the items in the combination, increasing their importance in calculations, for safety or other reasons. Load combinations are created based on either layer or class names.
To create and specify a load combination:
Select the command.
The Load Overview dialog box opens.
Click the Load Combinations tab.
Select whether the combination will be layer- or class-based, and then click Manage.
The Manage Load Combinations dialog box opens.
