Use the function Perform -- to define the shape to transform. Create(S: Shape from TopoDS; T: Trsf from gp; Copy: Boolean from Standard = Standard_False) returns Transform from BRepBuilderAPI; ---Purpose: Creates a transformation from the gp_Trsf , and -- applies it to the shape . If the transformation -- is direct and isometric (determinant = 1) and -- = Standard_False, the resulting shape is -- on which a new location has been set. -- Otherwise, the transformation is applied on a -- duplication of . Perform(me: in out; S : Shape from TopoDS; Copy: Boolean from Standard = Standard_False) ---Purpose: pplies the geometric transformation defined at the -- time of construction of this framework to the shape S. -- - If the transformation T is direct and isometric, in -- other words, if the determinant of the vectorial part -- of T is equal to 1., and if Copy equals false (the -- default value), the resulting shape is the same as -- the original but with a new location assigned to it. -- - In all other cases, the transformation is applied to a duplicate of S. -- Use the function Shape to access the result. -- Note: this framework can be reused to apply the same -- geometric transformation to other shapes. You only -- need to specify them by calling the function Perform again. is static; ModifiedShape(me; S: Shape from TopoDS) returns Shape from TopoDS ---Purpose: Returns the modified shape corresponding to . ---C++: return const& raises NoSuchObject from Standard -- if S is not the initial shape or a sub-shape -- of the initial shape. is redefined virtual; Modified (me: in out; S : Shape from TopoDS) ---Purpose: Returns the list of shapes modified from the shape -- . ---C++: return const & ---Level: Public returns ListOfShape from TopTools is redefined virtual; fields myTrsf : Trsf from gp; myLocation : Location from TopLoc; myUseModif : Boolean from Standard; end Transform;
