Merging polylines

[Leblond]

Hi everyone,

I need to merge the end point of one polyline to the start point of another one as attached (pink line)
Would you have any leads ?

Thank you very much !

as attached (pink line)

Seems like the picture or the file (preferred) got lost in translation !

Thank you ! here it is

Too bad you didn’t post your GH file with geometry internalized.

Super great ! Now, would you have an idea on how to achieve the picture below adding the pattern mentioned for each interconnected layer ?

Thank you so much

Yes, but since you can’t be bothered to post code/geometry without being asked, I can’t be bothered to reply any further.

Please read this, esp. #3:

Hello
I am not sure to understand your question. It seems obvious you want a path for 3d printing. There are many strategies but you show one with an open path (zig zag) and one with a closed path (circles).
I didn’t worked on open path, but on closed path.

First journey in 3D printing

Some weeks ago I began my journey in the 3d printing world. The main job was to generate 3d printer paths from closed curves which represent the intersection between a slice (plane or not) and a solid. The paths must be a single curve, which means the extruder never stop to extrude during the print. The results are very similar from what is presented here and on this paper “Connected Fermat Spirals for Layered Fabrication” The main tool is Offset from Clipper but there are many optimizatio…

If you want to stop extrusion, your approach could be enough but you will have to know when stopping the extrusion.

If you want not to stop extrusion, it is better to make closed single path on each layer and then join the curves.
It could be also good that your filling keep a circle for the base, it could be more beautiful.
I made a paid plugin to do all of that (the filling pattern, joining the curves …) but it seems not worth for me to let it online.

My goal is to print that “bullet” shape in one curve with multiple layers that include those patterns. Is it helpful ? Thank you !!

[magicteddy]

I’ll dive in with that as a solution ?

Thank you ! it is exactly what i was looking for
Do you know how to create a polyline from this now ?

[magicteddy]

It is already a polyline…
There is Explode if you need the segments or the vertices ?
