Connect lines neatly with lines

[안정훈]

Hello, I’m a beginner at Grasshopper. Please help me with this problem.

I made it with the same algorithm as the image above.

This is the kind of connection I want

Like this, the shape of the line is not connected as desired.
I want to ask you how to solve this problem.
Please I beg you.

I also attach the grasshopper file.

Hello,

Have a look at this, I cleaned the surface definition.
The projection works but connecting the curves afterwards doesn’t. How would you expect the path to behave given all these holes ? Could you draw a aketch of your desired result ?

Hello
it is not an easy task. This problem is related to this discussion

"spiralize" offset curves for fabrication

Hi, I want to modify these curves so I can use them as tool-paths. [image] The problem is though that due to the specifics of the fabrication process these can not be multiple curves – instead it has to be one continuous, smooth curve. The idea is to “sprialize” the curves like this: [image] For simple curves, with only one inner curve each it works like this: [image] >> [image] For curves with multiple inner curves I can’t quite figure it out. Has someone an idea to guide me in the…

My plugin Nautilus allows to make such pattern with a single curve, but it is not free.

Thank you so much for your answer!!

But it seems different from my final goal.
I posted the wrong example. I’m sorry.
I think the method you told me can only be used on a flat surface.
I want to project a surface of a curved surface onto a combined object.
I’ll upload the data again

Thank you for your reply.
But I just need a line that connects holes when I project them.
