Arc and curve don't join, is it normal?

Hi again!

I'm quite embarrassed to post this question, but, searching online, I couldn't find any answer.

I'm having this trouble with the join curves component. Since it's called join curves the first thing I have tried was to rebuilt the arc into a curve, but it didn't help.

I have considered switching the start-end point of the arc, but it didn't help either.

I have created a new nurbs curve from an array of points along the arc, but it didn't help either.

At last I have created the curve I needed from an array of points along the arc and the 2 curves, completely avoiding the join curves component.

Someone can tell me what am I missing?

Thank you in advance to anybody who could help.

Michele

Flatten the input to the Join.

I feared the answer would have been something as dumb as this...

I'm not sure why 1 curve from each component connected to the join component go in two list, I suppose because 1 curve is planar and the other 2 are 3D.

Thank you for your reply and sorry for the silly question.

'Join' fails without 'Flatten' because of different tree paths. As you can see, there are two branches - two separate lists. After 'Flatten', there is just one:

That doesn't mean you ALWAYS want to flatten the 'Join' input, though! If the two curves in the {0;0;0} path touched each other, they would have been joined, which sometimes is exactly what you want - multiple curves from 'Join'.
