MatchedBoolean4 Method (IBody2)

Performs a matched boolean on the specified bodies and supports an optional list of faces that match exactly.

) 

Parameters

OperationType

One of the following operation types:

  • SWBODYADD

  • SWBODYCUT

  • SWBODYINTERSECT

ToolBody

Array of bodies

NumOfMatchingFaces

Number of matching faces

FaceList1

First face list (see Remarks)

FaceList2

Number of matching faces

MatchingTolerance
Tolerance to use to check matching faces
ErrorCode

Error indicated as defined in swBodyOperationError_e

Remarks

The concept of match means that the caller tells the boolean operator beforehand which faces can be considered to coincide. Basically the caller performs part of the boolean operation.

Sometimes the application knows that two faces match because of the way the bodies are constructed; i.e., the application knows which faces are intended to match.

Having a list of matching face pairs may allow the matched boolean operator to resolve other geometric operations that otherwise it would not be able to work out. In general, providing matched faces speeds up the boolean operation and makes results more reliable.

The arguments FaceList1 and FaceList2 arguments can be empty lists. If matching face pairs are passed in, these faces must match such that:

  • the surface geometry is coinciding.

  •  for each edge in a face, there is an edge in the other face that coincides.

If MatchingTolerance is less than 1.0e-8 or 0.0, then a default tolerance of 2.0e-6 is used. You decide the tolerance value based on the similarities and subtle differences between the two bodies.

This method supports multibody parts.
