Generic classes "LProp_FuncCurExt", "LProp_FuncCurNul" and "LProp_NumericCurInf" from "LProp" package converted to the non-generic classes and moved to the "Geom2dLProp" package. Therefore names of this classes were changed to "Geom2dLProp_FuncCurExt", "Geom2dLProp_FuncCurNul" and "Geom2dLProp_NumericCurInf". Generic class "Sweep_LinearRegularSweep" from "Sweep" package converted to the non-generic classes and moved to the "BRepSweep" package. Therefore name of this class was changed to "BRepSweep_NumLinearRegularSweep". Also 2 internal classes of "BRepSweep_NumLinearRegularSweep" moved to "BRepSweep.cdl". Generic classes "Primitives_Wedge" and "Primitives_OneAxis" from "Primitives" package converted to the non-generic classes and moved to the "BRepPrim" package. Therefore names of this classes were changed to "BRepPrim_GWedge" and "BRepPrim_OneAxis". Also enum "Direction" moved to BRepPrim. Therefore all "Primitives" package was deleted. And some other minor changes were done. Internal classes Array2OfShapes and SequenceOfShapes from BRepSweep_NumLinearRegularSweep replaced to Array2OfShape and SequenceOfShape from TopTools.

deferred class OneAxis from BRepPrim
|
|
|
|
---Purpose: Algorithm to build primitives with one axis of
|
|
-- revolution.
|
|
--
|
|
-- The revolution body is described by :
|
|
--
|
|
-- A coordinate system (Ax2 from gp). The Z axis is
|
|
-- the rotational axis.
|
|
--
|
|
-- An Angle around the Axis, When the Angle is 2*PI
|
|
-- the primitive is not limited by planar faces. The
|
|
-- U parameter range from 0 to Angle.
|
|
--
|
|
-- A parameter range VMin, VMax on the meridian.
|
|
--
|
|
-- A meridian : The meridian is a curve described by
|
|
-- a set of deferred methods.
|
|
--
|
|
--
|
|
-- The topology consists of A shell, Faces, Wires,
|
|
-- Edges and Vertices. Methods are provided to build
|
|
-- all the elements. Building an element implies the
|
|
-- automatic building of all its sub-elements.
|
|
--
|
|
-- So building the shell builds everything.
|
|
--
|
|
-- There are at most 5 faces :
|
|
--
|
|
-- - The LateralFace.
|
|
--
|
|
-- - The TopFace and the BottomFace.
|
|
--
|
|
-- - The StartFace and the EndFace.
