Detailed Description

The class represents the Intersection phase of the Boolean Operations algorithm. It performs the pairwise intersection of the sub-shapes of the arguments in the following order:

1. Vertex/Vertex;
2. Vertex/Edge;
3. Edge/Edge;
4. Vertex/Face;
5. Edge/Face;
6. Face/Face.

The results of intersection are stored into the Data Structure of the algorithm.

Additionally to the options provided by the parent class, the algorithm has the following options:

• Section attributes - allows to customize the intersection of the faces (avoid approximation or building 2d curves);
• Safe processing mode - allows to avoid modification of the input shapes during the operation (by default it is off);
• Gluing options - allows to speed up the calculation on the special cases, in which some sub-shapes are coincide.

The algorithm returns the following Warning statuses:

• BOPAlgo_AlertSelfInterferingShape - in case some of the argument shapes are self-interfering shapes;
• BOPAlgo_AlertTooSmallEdge - in case some edges of the input shapes have no valid range;
• BOPAlgo_AlertNotSplittableEdge - in case some edges of the input shapes has such a small valid range so it cannot be split;
• BOPAlgo_AlertBadPositioning - in case the positioning of the input shapes leads to creation of small edges;
• BOPAlgo_AlertIntersectionOfPairOfShapesFailed - in case intersection of some of the sub-shapes has failed;
• BOPAlgo_AlertAcquiredSelfIntersection - in case some sub-shapes of the argument become connected through other shapes;
• BOPAlgo_AlertBuildingPCurveFailed - in case building 2D curve for some of the edges on the faces has failed.

The algorithm returns the following Error alerts:

• BOPAlgo_AlertTooFewArguments - in case there are no enough arguments to perform the operation;
• BOPAlgo_AlertIntersectionFailed - in case some unexpected error occurred;
• BOPAlgo_AlertNullInputShapes - in case some of the arguments are null shapes.
