Detailed Description

One of the four types of interactive object in AIS,comprising dimensions and constraints. Serves as the abstract class for the seven relation classes as well as the seven dimension classes. The statuses available for relations between shapes are as follows:

0 - there is no connection to a shape;
1 - there is a connection to the first shape;
2 - there is a connection to the second shape. The connection takes the form of an edge between the two shapes.

Reimplemented from AIS_InteractiveObject.

◆ SetExtShape()

void AIS_Relation::SetExtShape ( const Standard_Integer theIndex )

inline

Allows you to set the status of the extension shape by the index aIndex. The status will be one of the following:

0 - there is no connection to a shape;
1 - there is a connection to the first shape;
2 - there is a connection to the second shape.

◆ SetFirstShape()

virtual void AIS_Relation::SetFirstShape ( const TopoDS_Shape & aFShape )

virtual

◆ SetPlane()

void AIS_Relation::SetPlane ( const Handle< Geom_Plane > & thePlane )
