ShapeFix_FreeBounds Class Reference

This class is intended to output free bounds of the shape (free bounds are the wires consisting of edges referenced by the only face). For building free bounds it uses ShapeAnalysis_FreeBounds class. This class complements it with the feature to reduce the number of open wires. This reduction is performed with help of connecting several adjacent open wires one to another what can lead to: More...

Detailed Description

This class is intended to output free bounds of the shape (free bounds are the wires consisting of edges referenced by the only face). For building free bounds it uses ShapeAnalysis_FreeBounds class. This class complements it with the feature to reduce the number of open wires. This reduction is performed with help of connecting several adjacent open wires one to another what can lead to:

1. making an open wire with greater length out of several open wires
2. making closed wire out of several open wires

The connecting open wires is performed with a user-given tolerance.

When connecting several open wires into one wire their previous end vertices are replaced with new connecting vertices. After that all the edges in the shape sharing previous vertices inside the shape are updated with new vertices. Thus source shape can be modified.

Since interface of this class is the same as one of ShapeAnalysis_FreeBounds refer to its CDL for details.

Constructor & Destructor Documentation

ShapeFix_FreeBounds::ShapeFix_FreeBounds

(

)

Empty constructor.

ShapeFix_FreeBounds::ShapeFix_FreeBounds	(	const TopoDS_Shape &	shape,
		const Standard_Real	sewtoler,
		const Standard_Real	closetoler,
		const Standard_Boolean	splitclosed,
		const Standard_Boolean	splitopen
	)

Builds forecasting free bounds of the <shape> and connects open wires with tolerance <closetoler>. <shape> should be a compound of faces. Tolerance <closetoler> should be greater than tolerance <sewtoler> used for initializing sewing analyzer, otherwise connection of open wires is not performed.

ShapeFix_FreeBounds::ShapeFix_FreeBounds	(	const TopoDS_Shape &	shape,
		const Standard_Real	closetoler,
		const Standard_Boolean	splitclosed,
		const Standard_Boolean	splitopen
	)

Builds actual free bounds of the <shape> and connects open wires with tolerance <closetoler>. <shape> should be a compound of shells.
