Create Hull Curve

Purpose:

To create or modify a hull curve in a hull surface.

Prerequisites:

None.

Instructions:

• In create mode, you must give a curve definition and a hull curve name. If a curve is already selected, it will be used as the curve definition. If several curves are selected, the hull curves may be automatically named. In this case, you may enter the name of the first hull curve, with the numerical part to increase for every following curve surrounded by "<" and ">" symbols. If "<" and ">" are not a part of the name, a running number starting at one will be added at the end of the entered name. Alternatively, the name may include a repetition term within "<" and ">", where the repetition term will generate the names of the curves. Examples of valid entries in the name field are "HCURVE", "HCURVE<5>C" and "HCURVE<5(10)25>C" (with the last example valid only with three selected curves).

• In modify mode, you may change any part of the hull curve, including its name and box. The Modify Curve button lets you change the curve definition. Since the hull curve is trimmed with the box, the extension of the hull curve can be changed by modifying the box co-ordinates.

Options:

None.

Result:

• In create mode, a new hull curve will be created and selected. The Select Submenu - Apply function must be used to commit the creation of the curve.

• In modify mode, the hull curve will be updated with the new definition data. To make the changes permanent, Apply must be used. Using the Select Submenu - Deactivate function before the changes have been applied will undo them.
