Detailed Description

Chamfer surface.

Chamfer surface is ruled surface constructed from two curves on the mating surfaces: curve1 and curve2. The first surface parameter coincides with the parameter of curves curve1 and curve2. The second parameter is changed from zero (points coincide with curve1) to unit (points coincide with curve2). In contrast to other surfaces functions PointOn and Derive ... chamfer surface does not correct the first parameter when it is out of domain bounds. Section of surface along its second parameter is a line segment.

◆ Duplicate()

MbSpaceItem& MbChamferSurface::Duplicate ( MbRegDuplicate * iReg = nullptr ) const

overridevirtual

Create a copy of the object.

Create a copy of an object using the registrator. Registrator is used to prevent multiple copy of the object. If the object contains references to the other objects, then nested objects are copied as well. It is allowed not to pass registrator into the function. Then new copy of object will be created. While copying of single object or set of not connected objects, it is allowed not to use registrator. Registrator should be used if it is required to copy several connected objects. It is possible, that objects connection is based on the references to common objects. Then, while copying without using of registrator, it is possible to obtain set of copies, that contain references to the different copies of the same nested object, that leads to loss of connection between copies.

Parameters

[in] iReg - Registrator.

Returns: A copy of the object.
