Hi David, thank you a lot!
Unhappily I have some question more - how it is possible to make normal loop(like in vbscript) then I have - if I have the two parameters to check(two lines are intersected by a cylinder), can I write so If (Not RhUtil.RhinoCurveBrepIntersect(CVR1, cyl, 0.001, overlaps1, points1)) and (Not RhUtil.RhinoCurveBrepIntersect(CVR2, cyl, 0.001, overlaps2, points2)) Then Continue For If (points.Count() = 0) and (points2.Count() = 0) Then Continue For Thank you and best regards! Dimitry
