Delete segment of a curve

[kiryha]

I need to delete round part of the curve. The only way I manage to do it gives the desired result on the right side but remain segment on the left side (bottom shape).
I need a second object which will exclude initial circles.

Hey, I've fixed the issue - the entire line was being stored as a single primitive so when you deleted the points, it kept the line connected. All I did was add a 'convert line' SOP before the point wrangle, which makes every line segment a separate primitive. (I also turned off the rest length attribute since you probably won't need it).

Hi, Stephen,

That's works, thanks! However, the resample node placed after OUT_LINES does not work as expected (rising Length has no effect). I need dramatically reduce the amount of points there.

This should fix it:

delete_segment_02_fixed.hipnc

Connectivity is just setting a class attribute on the points for each connected piece, and then the add node is deleting all the prims and creating them again using that class attribute.

Ok, that solution works, thanks! 

But I wonder what the convertLine SOP did that resample stop working...

here's my way...(left branch)

Cool, Vusta! I was trying to go this way with group transfer as well but did not get it working, nice trick with facet SOP.
