Dear GMSH users, By applying the BooleanIntersection between a volume and a curved surface, I can get a decent BSpline intersection curve loop on the surface. The problem I am facing is that the BooleanIntersection by default gives me an “extra” point on the intersection edge, which I don’t want (for good reasons). A screenshot is posted below. The ‘Cylinder 23(OCC)’ is the outcome of Boolean intersection. What I need are the four points (22, 23, 24, 25) and four associated BSpline curves on the Surface. Somehow, I couldn’t get rid of the extra point (26), which is located at the z max position of Surface 23(OCC). My guess is that the additional point is kinda of a *reference point* created by the BooleanIntersection function.
Is it possible to workaround this issue? I know Compound BSpline could potentially merge curves (i.e. connecting BSplines 27 and 28 here into one), but it only works for the built-in CAD kernel. Is there an equivalent function for OCC kernel? Any comments/suggestions are appreciated.
