The membership flag

class TopTrans_CurveTransition(*args)

Bases: object

• Create an empty Curve Transition.

  rtype

  None

Compare()

• Add a curve element to the boundary. If Or is REVERSED the curve is before the intersection, else if Or is FORWARD the curv is after the intersection and if Or is INTERNAL the intersection is in the middle of the curv.

StateAfter()

• returns the state of the curve after the intersection, this is the position relative to the boundary of a point very close to the intersection on the positive side of the tangent.

  rtype

  TopAbs_State

StateBefore()

• returns the state of the curve before the intersection, this is the position relative to the boundary of a point very close to the intersection on the negative side of the tangent.

  rtype

  TopAbs_State

property thisown

The membership flag

class TopTrans_SurfaceTransition(*args)

Bases: object

• Create an empty Surface Transition.

  rtype

  None

Compare()

• Add a face element to the boundary. //! - S defines topological orientation for the faceS FORWARD means: along the intersection curve on the reference surface, transition states while crossing the face are OUT,IN. S REVERSED means states are IN,OUT. S INTERNAL means states are IN,IN. //! - O defines curve’s position on faceO FORWARD means the face is before the intersection O REVERSED means the face is AFTER O INTERNAL means the curve intersection is in the face.
