The engineer can assign fixity to beams, columns, horizontal braces or vertical braces by selecting the Assign - Beam - Fixity, Assign - Column – Fixity, Assign – Horizontal Brace - Fixity or Assign - Brace - Fixity commands respectively. From the dialog that appears the engineer should select the appropriate fixity conditions.

After the appropriate fixity is selected the engineer can assign this fixity condition to a single member (click on Single), to multiple members (click on Fence) or to all members (click on All). If Single is selected the dialog will close and a target cursor will be made available. Click on each member to assign fixity. If Fence is selected the dialog will close and a fence cursor will be made available. Click and drag a rectangle around all the members to assign fixities. Note that fixity is only assigned to members comprised of the same type (beam, column or brace) as the menu command issued.

To clear member fixity automatically displayed for the assign operation select the Reset Model toolbar button. To display member fixity select the appropriate option from the View-Members Dialog.
