Select Global, Braced or Unbraced, for both the major and minor axis. "Global" means that the bracing will be determined by the global criteria.

Single: To assign bracing to one column, click Single. This will cause the dialog box to close and the target cursor to appear. Click on columns with the target to make the assignment. The symbols on the screen will update to indicate that the assignment has been made.

Fence: To assign bracing to a group of columns, click Fence. This will cause the dialog box to close and the rectangle cursor to appear. Click and drag the rectangle to include the columns to which the assignment will be made. The symbols on the screen will update to indicate that the assignment has been made. (HINT: When assigning in Fence mode, it is often a good idea to be in plan or elevation to insure that only the desired columns are fenced)

All: Clicking the All button will cause the dialog to close and the assignment made to all steel columns in the model.
