17 class Plane from StdPrs
19 inherits Root from Prs3d
21 ---Purpose: A framework to display infinite planes.
24 Surface from Adaptor3d,
25 Presentation from Prs3d,
27 TypeOfLinePicking from Prs3d,
31 Add(myclass; aPresentation: Presentation from Prs3d;
32 aPlane : Surface from Adaptor3d;
33 aDrawer : Drawer from Prs3d);
