The Process - Results - Member Forces Envelope command displays the maximum or minimum member forces for all the frame members in the model.

When the command is invoked, the user first selects the "max" or "min" envelope option. The envelope is evaluated among all currently analyzed load cases. The user then selects the force type that is to be displayed. The types include major and minor shear, major and minor moment, axial load and torsion. The Apply button causes the "max" or "min" member force values to be displayed.

Close terminates the command. When the command is terminated the currently displayed force envelope values remain on the screen. They can be cleared by selecting the Reset Model button.
