This command is used to assign groups of reinforcement patterns to a concrete column line (see Section 3.9.4 for details about how these patterns are created). Up to three pattern groups can be assigned to one column line. At least one pattern group must be assigned to a column line for that column line to be designed.

Select column lines by placing a check in the box next to the pattern group label. The dialog is closed by selecting the Single, Fence or All buttons. Closing the dialog puts the user into selection mode as described above. The status bar prompts the selection process.
