Sweep 1 align cross sections

[Reda_Mejbar]

Hello,

I would appreciate your ideas on how I can get a clean sweep between these two cross sections in Grasshopper? is there a way to align the sections, not only the seams? Thank you

I am aware that if I split the curve as shown in the picture, and perform two seperate sweep then the result is good, but is there a way to do it withut the need to split?

Why would this work? Rail curve not internalized?

ah sorry, I internalised all of them now. Thanks

I tried many ways but these two section curves don’t “play nice”. This results in two breps that must be joined. Note: Rebuild curves doesn’t “observe” discontinuity points.

Definitively overkill.
This works (partially) for this single case… will probably fail otherwise.
Doing this on Rhino is much simpler and faster.

.GetNextDiscontinuity with tolerances at zero can extract relevant points, but the amount of features of the two shapes are different.

I suppose you can continue to ‘adjust’ the sweep by adding more sections:

Thanks, it seems It would be better to change the cross sections for better results or doing it in Rhino. but this is the closest results. Thanks
