Type Tab

The Type tab is used to change the defining curves or generation method for existing patches. Patches generated by the Patch and Curve Editor cannot have their type changed here.

Use the Type Tab

1. Select the generation method from either Scatter, Boundary or Regular.

2. Select the defining curves as appropriate, either a combination of Sections, Waterlines and or Buttocks check boxes for scatter or an individual orthogonal curve type from the Defining Curves pulldown list for regular.

3. Select the relevant patches from the list or the All check box and click the Set button.

The Auto fit check box is used to automatically fit the surface patch after changing its definition, to disable this option it must be deselected. The Show Points toggle check box can be used to display the generated points.

The patch list shows three columns, Patch, Fitted and Curves.

The Patch column shows the patch name and an icon to indicate the patch type and data form:

Table 1: 11. Patch List images and their meaning.

The patch data form is an indication of whether the patch data is flat or not before any continuity is set.

The Fitted column indicates whether a patch is fitted or not.

The Curves column indicates which curves were used to create the patch data for fitting (S=Sections, W=Waterlines, B=Buttocks).

By clicking the Right Mouse button over a list, a convenience menu is displayed. This provides facilities for displaying the currently selected patches (either fitted, unfitted or limits) or for interactively selecting patches from a graphics window.
