Hello,
I am new to use Grasshopper, and I did not find the answer on the forum, I hope anyone can help

I have Multiple curves, and I want to explode all and group all the parallel ones . What should I do ?
Thanks in advance.

Hello
If by curve you mean line, you can extract vector
Unitize them, orient them and use sets to group them or group points (vector indeed)

If they’re all in one plane (xy), the following will do it.
