Displays the options that you use to place an offset reference curve in the model.

 Reference Curve by Offset Properties

Opens the Reference Curve by Offset Properties dialog box, which you use to view and modify the properties of the reference curve that you are about to place in the model. For more information, see Reference Curve By Offset Properties Dialog Box.

 Plate System

Specifies the plate system in which you want to place a reference curve. You can select multiple plate systems to place multiple reference curves at the same time. The software uses the same information for each reference curve. After placement, the reference curves are unrelated to each other and can be edited as individual entities.

 Base Curve

Specifies an existing curve or grid plane from which to offset the reference curve. The intersection of the grid plane and the plate system defines the base curve.

 Offset

Defines the offset parameters and direction from the base curve. See the Offset Curve Definition Controls section below.

 Boundaries

Defines the boundaries of the reference curve. You can define the boundaries by selecting objects in the model. If you select objects in the model and those objects are moved, the software automatically resizes the reference curve to maintain the boundary relationship. See the Boundary Definition Controls section below.

Finish

Places the reference curve using the defined parameters.

 Reject

Clears all selected objects.

 Accept

Accepts all selected objects.

Type

Specifies the curve type. Select Reference, Grid, Mark, Tangent, or Knuckle.

Name

Defines the name of the reference curve.

Offset Curve Definition Controls

 Unlimited

Defines offset curves without a stop limit.

 Stop Limit

Defines offset curves with a stop limit. By using a stop limit, you can select an edge, profile landing curve, connection reference curve, or reference curve to control the landing curves being created. If you type an offset value and the Offset lock is locked, then landing curves are applied at increments of the offset value until the selected stop limit is reached. If the Offset lock is unlocked and a value has been defined for Count, then the landing curves equal to the number entered in the Count box are equally spaced between the base curve and the stop limit.

Offset Lock

Locks the Offset value, disabling updates of the offset value by mouse moves.

Offset

Specifies the offset distance between the base curve and the landing curve that you are defining. If you type 0, the landing curve is place on the base curve. This box may also display the offset distance as defined by mouse movements.

Method

Specifies an offset method. You can select transverse, longitudinal, vertical, or girth.

Count

Specifies how many reference curves are created, each equally spaced by increments of the offset value.

Step

Defines an increment that the software uses as you dynamically move the mouse. If you entered a value in the Offset box, then this control is not used.

Boundary Definition Controls

 Pick Boundaries

Selects objects in the model or in the Workspace Explorer to define the boundaries. This option is only available when you are defining the boundaries.

 Solve Ambiguity

If the objects that you selected in the model for the boundary define an ambiguous solution, then the software prompts you to select one bounded section to clarify the needed boundary. This ambiguity only occurs if one of the boundaries wraps around both sides of the profile or seam, such as the hull. Move the cursor over a bounded section, and then click to select.

 Boundary List

Opens the Boundary List dialog box. This dialog box allows you to review and define the boundaries. For more information, see Boundary List Dialog Box.
