Group.Curves - Not connecting curves get grouped

Hello Dynamo Friends :smiley:

I want to make polylines out of the sketch lines of a slab.
I`m getting the error for the long black line on index 8.

So i tried to delete all other lines and test if that helps, and that actually did work:

Then i saw the problem are these 4 lines:

Because they get grouped with the long line as you can see in the first picture.

But they should not because they are not connected:

So the problem is the group.curves node, so what are my alternatives?

Happy about any help, thanks!

Kind Regards :slight_smile:

Ok, sorry, i got it, there is a tolerance of 0.1 in the code.
i changed it to 0.001 and it works now :slight_smile:
