Farthest points between curves

[Willem (Willem Derks)]

@clement

Hi Vitaly, there is a GetDistancesBetweenCurves method in RhinoCommon which might help. It gives the parameters on each curve where the distance is maximum. It is not the fasted though. If you use polyline segments, they must be passed to the method as type LineCurve .

@sadovshikov A note of caution: there is an open bug report for GetDistancesBetweenCurves

CrvDeviation failing unexpected

Hi, I found that Rhino.Geometry.Curve.GetDistancesBetweenCurves produces unpredictable failures for similar type curve sets. Find attached a V6 file that expresses the issue with the CrvDeviation command similar as found when using the GetDistancesBetweenCurves method. CrvDeviation.3dm (73.2 KB) [image] Thanks -Willem

CrvDeviation fail

Why doesn’t CrvDeviation work between any of these 3 curves? (Tested in V5 and WIP) The RhinoCommon Curve.GetDistancesBetweenCurves method also fails of course. Thanks, --Mitch No_CDev.3dm (233.4 KB)
