MergeSrf bug

I have two tange surfaces, which I want to covert into a single surface. As far as I know, this could be achieved with MergeSrf. However, the result is not as expected…
Am I doing something wrong? Is there a betterway?

Hi N- please post the surfaces. Does MakeUniform clean up?

Ah… the inputs are arcs - they are tangent and merging smoothly wants to make them G2. So, for tangent arcs, set Smooth=No in MergeSrf. You will have a potential ‘kink’ at the seam however.


:confused: a bit counterintuitive… … but it seems to do the trick…
