If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called.

Determines whether or not this surface shape is degenerate. This occurs when surface shapes have an area of 0.

Indicates if the set of points lying on the boundary of this shape is empty.

Indicates if this shape has finite extents.

Gets/sets the normal for this plane. The getter returns a unit vector.

Gets/sets the offset for this plane. The offset is the translation from the origin along the normal direction.

The 3D coordinate space in which this shape is to be interpreted.

Get/sets the ShapeState for this shape.

Returns the complete set of state flags supported on this object. The flags may be indexed by name as shown in the following C# code snippet: if (changedObject.StateFlags["Color"] & eventArgs.StateFlags) { ... }
