Bases: object

static Complement()

• Reverses the interior/exterior status of each side of the object. So, to take the complement of an object means to reverse the interior/exterior status of its boundary, i.e. inside becomes outside. The method returns the complementary orientation, following the rules in the table below: FORWARD REVERSED REVERSED FORWARD INTERNAL EXTERNAL EXTERNAL INTERNAL //! Complement complements the material side. Inside becomes outside.

  param Or

  type Or

  TopAbs_Orientation

  rtype

  TopAbs_Orientation

static Compose()

• Compose the Orientation <Or1> and <Or2>. This composition is not symmetric (if you switch <Or1> and <Or2> the result is different). It assumes that <Or1> is the Orientation of a Shape S1 containing a Shape S2 of Orientation Or2. The result is the cumulated orientation of S2 in S1. The composition law is//! Or2 FORWARD REVERSED INTERNAL EXTERNAL Or1 ————————————- FORWARD | FORWARD REVERSED INTERNAL EXTERNAL | REVERSED | REVERSED FORWARD INTERNAL EXTERNAL | INTERNAL | INTERNAL INTERNAL INTERNAL INTERNAL | EXTERNAL | EXTERNAL EXTERNAL EXTERNAL EXTERNAL Note: The top corner in the table is the most important for the purposes of Open CASCADE topology and shape sharing.

static Print()

• Prints the name of Shape type as a String on the Stream.

  param theStream

  type theStream

  Standard_OStream

  rtype

  Standard_OStream* Prints the name of the State <St> as a String on the Stream <S> and returns <S>.

  param St

static Reverse()

• xchanges the interior/exterior status of the two sides. This is what happens when the sense of direction is reversed. The following rules apply: //! FORWARD REVERSED REVERSED FORWARD INTERNAL INTERNAL EXTERNAL EXTERNAL //! Reverse exchange the material sides.

  param Or

  type Or

  TopAbs_Orientation

  rtype

  TopAbs_Orientation

static ShapeOrientationFromString()

• Returns the shape orientation from the given string identifier (using case-insensitive comparison). @param theOrientationString string identifier returns shape orientation or TopAbs_FORWARD if string identifier is invalid

  param theOrientationString

  type theOrientationString
