A, P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P15, P16, P17, P18
Defines an area by connecting keypoints.
P1,P2,P3, . . . ,P18List of keypoints defining the area (18 maximum if using keyboard entry). At least 3 keypoints must be entered. If
P1= P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI).
Notes
Keypoints (P1 through P18) must be input
in a clockwise or counterclockwise order around the area. This order also determines the positive
normal direction of the area according to the right-hand rule. Existing lines between adjacent
keypoints will be used; missing lines are generated "straight" in the active coordinate system
and assigned the lowest available numbers (NUMSTR). If more than one line
exists between two keypoints, the shorter one will be chosen. If the area is to be defined with
more than four keypoints, the required keypoints and lines must lie on a constant coordinate
value in the active coordinate system (such as a plane or a cylinder). Areas may be redefined
only if not yet attached to a volume. Solid modeling in a toroidal coordinate system is not
recommended.
