This form is used to edit P-Shapes by their parameters. One or more P-Shapes of the same type may be modified. A P-Shape may be selected by its label. The P-Shapes listed in the listbox may be filtered by name or by type, e.g., Rectangle, Triangle, etc. P-Shapes which are listed in the listbox may be displayed on the screen using the “Show P-Shape” button and the display is reset using the “Reset” button.

P-Shapes can also be selected off the screen using the “Select P-Shape(s)” select data box . Since different types of P-Shapes may be selected in either the listbox or in the select data box, the “Filter for P-Shape(s)” button is used to isolate one type of P-Shape.

If only entity is selected for edit, then you can edit the P-Shape Label. The parameters to edit are identical to the Create P-Shape forms for each geometry type. If multiple entities are selected, certain parameters may not be editable such as the Axis of Revolution for cones (spheres, paraboloids) since modifying that parameter to be the same will transform all cones edited to be in the same location.
