Set the tolerances used by the algorithms: — Implicit - Parametric — Parametric - Parametric — Implicit - Implicit.
TolArc is used to compute the intersections between the restrictions of a surface and a walking line.
TolTang is used to compute the points on a walking line, and in geometric algorithms.
Fleche is a parameter used in the walking algorithms to provide small curvatures on a line.
UVMaxStep is a parameter used in the walking algorithms to compute the distance between to points in their respective parametrtic spaces.
| Standard_Boolean IntPatch_Intersection::TangentFaces | ( | ) | const |
Returns True if the two patches are considered as entierly tangent, i-e every restriction arc of one patch is inside the geometric base of the other patch.
