Difficulty in creating equal curvature to a converted entity.

Hi,

I'm trying to connect a spline to a converted entity (a curve) in a 2-D sketch. I can select "equal curvature", but when I show the curvature combs, it is obviously not equal curvature.

I'm trying to apply 'equal curvature' to a boundary surface, but if I can't get the guide curves to have equal curvature, it fails.

Thanks

It's possible that equal curvature is already being achieved, but the combs might look unequal due to the presence of an inflection point. Try tweaking the control handles to achieve a smoother transition. You can also increase the resolution of the curvature combs to better show localized changes in curvature.

  It is definately not an inflection point. The curvature of the top comb (converted entitiy) does not go to zero, but the spline with curvature condition specified, always starts at zero when connecting to a converted entitiy.

    Samuel,
    
    I tried duplicating your problem and couldn't do it. My splines always matched the curvature of the converted arc. I tried 2, 3 and 4 point splines. If I made a spline with points very close to the end where the curvature continuity was applied and the spline curved away from the direction of the converted arc, I could end up with an inflection point very close to the end that would make it look somewhat like yours. I would have to zoom in very close to the end to see the inflection point if I had the spline handles turned on.
