Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0
C#
public static Brep[] CreateBooleanDifference(
IEnumerable<Brep> firstSet,
IEnumerable<Brep> secondSet,
double tolerance,
bool manifoldOnly
)VB
Public Shared Function CreateBooleanDifference (
firstSet As IEnumerable(Of Brep),
secondSet As IEnumerable(Of Brep),
tolerance As Double,
manifoldOnly As Boolean
) As Brep()
- firstSet
- Type: System.Collections.Generic.IEnumerable(Brep)
First set of Breps (the set to subtract from). - secondSet
- Type: System.Collections.Generic.IEnumerable(Brep)
Second set of Breps (the set to subtract). - tolerance
- Type: System.Double
Tolerance to use for difference operation. - manifoldOnly
- Type: System.Boolean
If true, non-manifold input breps are ignored.
Type: Brep[]
An array of Brep results or null on failure.
The solid orientation of the breps make a difference when calling this function
