Selecting the Assign-Frame Numbers command causes the Assign Lateral Frame Numbers dialog box to be displayed. From this dialog the engineer can assign frame numbers to Lateral Frame members. The primary purpose of the frame numbers is to group frame members for output purposes. In Seismic Provision mode the frame numbers have design implications as described in the option Use Frame Nos. to Designate a Frame Line described in Codes.

Enter a number in the Frame Number edit box to assign to members. Select the member types to assign this frame number to by clicking the appropriate option box under the Assign To area. Note that different member types, within the same frame, can be assigned different numbers.

After the appropriate frame numbers and member types values are specified, the engineer can assign the criteria to a single member (click on Single), to multiple members (click on Fence) or to all members (click on All). If Single is clicked the dialog will close and a target cursor will be made available. Click on each

section to assign the Frame Number to. If Fence is clicked the dialog will close and a fence cursor will be made available. Click and drag a rectangle around all the members to assign the Frame Number to.

To view member frame numbers select the appropriate option from the View-Members Dialog.
