class Point from AIS inherits InteractiveObject from AIS
---Purpose: Constructs point datums to be used in construction of
-- composite shapes. The datum is displayed as the plus marker +.

Create(aComponent : Point from Geom)
returns mutable Point from AIS;
---Purpose:
-- Initializes the point aComponent from which the point
-- datum will be built.
Signature(me) returns Integer from Standard is redefined;
---Purpose: Returns index 1, the default index for a point.
---C++: inline
Type(me) returns KindOfInteractive from AIS is redefined;
---Purpose: Indicates that a point is a datum.
---C++: inline
Component(me: mutable) returns Point from Geom
is static;
---Purpose: Returns the component specified in SetComponent.
SetComponent(me: mutable;aComponent:Point from Geom )
is static;
---Purpose: Constructs an instance of the point aComponent.
AcceptDisplayMode(me;aMode:Integer from Standard) returns Boolean from Standard is redefined static;
---Purpose: Returns true if the display mode selected is valid for point datums.

---Purpose: Allows you to remove color settings.
SetMarker(me:mutable; aType : TypeOfMarker from Aspect);
---Purpose: Allows you to provide settings for a marker. These include
-- - type of marker,
-- - marker color,
-- - scale factor.
UnsetMarker(me:mutable);
---Purpose: Removes the marker settings.
