If you are designing a catamaran you may find it useful to use the Mirror Stringers command to duplicate the stringers on one side of the catamaran hull onto the other side of the hull. Mirroring can also be used to mirror longitudinally about a station or vertically about a particular height.

To mirror a stringer or stringers:

Ø        Select the stringer or stringers to be mirrored

Ø        Choose Mirror Stringer from the Stringer menu

A dialog box will appear with fields for the centre of mirroring, the direction of mirroring and the surface the stringer is to be mirrored on to

Ø        Enter the position the stringer is to be mirrored about

In the case of a catamaran this will be the offset of the demi-hull centreline

Ø        Click a radio button to indicate how the stringers are to be mirrored

Ø        Select the surface from the pop-up menu that the stringer is to be mirrored on to

In the case of a catamaran this will be the inner hull if the original stringers are on the outer hull and the outer hull if the stringers are originally on the inner hull

Ø        Click the OK button

The stringers will be mirrored and placed on the selected surface
