When you wish to create a structure with one or more axes of symmetry, you can use the Mirror command to mirror the structure you have drawn.

To mirror members in a frame

§    Select the members to be mirrored

§    Choose Mirror… from the Geometry menu

A dialog box will appear with fields for the direction to mirror and the location of the plane about which mirroring will take place.

§    Choose the radio button of the plane about which mirroring will occur

§    Enter the location of the plane along that axis

§    Click the OK button

If you leave the Connect to existing check box checked, Multiframe will automatically create a connection between the selected joints and the mirrored members.

If you leave the Duplicate Selection check box checked, Multiframe will duplicate the selected members otherwise the existing members will be moved.
