The default trial groups specified in the Criteria - Trial Group Defaults command can be overridden on a column line by column line basis. This is done using the Assign - Trial Groups command. There are two options:

• Global is used to specify that the Trial Groups used for design are to be those specified in the Criteria – Trial Groups command.
• Use Trial Group(s) is used to specify specific trial groups.

Note that to clear a previous assignment, invoke the Assign – Trial Groups command and assign the Global option.

In the Assign Trial Groups dialog, select the check box above the Trial Group to activate that group, and specify from the list of groups a group for each shape. A Trial Group can also be deactivated by deselecting the check box above it.

Separate trial groups are set for standard columns and for hanging columns. When the assignment is made, the appropriate assignment is made based on the column type.

In Single mode, select the column line for which the Trial Groups assignment is to be assigned. In Fence mode fence entirely all column lines for which the Trial Group assignment is to be assigned. All assigns the Trial Group assignment to all column lines in the entire model.
