The CSA Phi Factors setup window ( Job Settings )

• The phi factors that you can set on this window directly affect the calculations that connection design makes when ' CSA8 ' or ' CSA9 ' is the " Connection design method ." The default settings for this window are the phi factors recommended by CISC, the Canadian Institute of Steel Construction.
• To open this window

To close CSA Phi Factors :

"OK" (or the Enter key) closes the CSA Phi Factors window and saves the settings on it to the Job Settings file in your current Job .

Note: If you have made changes to this window after having added members to the 3D model, you should interactively mark for processing (or Process Selected ) all members in your current Job, then Process and Create Solids in order to ensure design consistency throughout the Job.

"Cancel" (or the Esc key) closes this window without saving any changes made to it.

"Reset" undoes all changes made to this window since you first opened it. The window remains open.
