MeshIntersectionsTolerancesCoefficient

Offers a requested adjustment coefficient for mesh-mesh intersections tolerances. The value can be used to multiply the document absolute tolerance.

This is only a UI value; it is up to developer to honor (or not) this request, depending on application needs.

Code Example

CurveBrep(Curve, Brep, Double, .Curve.., .Point3d..)

Intersects a curve with a Brep. This function returns the 3D points of intersection and 3D overlap curves. If an error occurs while processing overlap curves, this function will return false, but it will still provide partial results.

CurveBrep(Curve, Brep, Double, Double, .Double..)

Intersect a curve with a Brep. This function returns the intersection parameters on the curve.

Public Method
Static Member

CurveBrep(Curve, Brep, Double, .Curve.., .Point3d.., .Double..)

Intersects a curve with a Brep. This function returns the 3D points of intersection, curve parameters at the intersection locations, and 3D overlap curves. If an error occurs while processing overlap curves, this function will return false, but it will still provide partial results.
