Self Weight is a command that instructs the program to consider the self weights of entities in the model.
The command can be applied by clicking Create > Draw Loads > Self Weights, which opens the Self Weights dialog.
The assignment starts by selecting the load case with which the self weight load is to be associated. Select the global direction and then specify a multiplier.
The most common use is Dead Load, Global Y, factor of -1.
Self Weight applies to all elements in the model that have their Self Weight control set to "Include":
To view the Self Weight control for members, open the Members table by clicking Tables > Members:
To view the Self Weight control for shells, open the Members table by clicking Tables > Shells:
There is an analogous column in the Bricks table, as well.
To remove a Self Weight assignment globally, one option is to use a factor of zero in the multiplier field in Create > Draw Loads > Self Weights. Another option is to use the Create > Draw Loads > Self Weight Exclusion command.
This method allows the self weight to be excluded for all or for a selected set of members, shells, and or bricks.
