Warning: PolyCurve.ByJoinedCurves operation failed

Hi everyone,

I should preface this post by stating that I’m new to Dynamo and I’m trying to get a script to work for an apartment block (I’m also running the packages lunchbox and archilab).

I get the following error under the Poly.Curve.ByJoinedCurves field

“Warning: PolyCurve.ByJoinedCurves operation failed. Curve join produced more than one WIRE in PolyCurve”

I’d be really grateful if someone could point out what’s causing this issue.

Hi everyone,
I got the same error.
And I also had something weird happening. This node doesn’t work in my current script but it does with the exact same objects in another script.
Explanation : I put “3D profiles” along a curve, through a generic model, in order to make a Solid.ByLoft out of them.

Then I want to get the curves out of the 3D profile (18 curves to join in one single polycurve) :

This node worked at some point. Now it gets only 1 or 2 of the 18 curves in my profile. But if I copy-paste the exact same nodes with the same profiles in another Dynamo script, it works perfectly. This is what I get when it doesn’t work :

Does anyone have a clue ?

I run into the same issue , have you solved this yet? :rofl:

No I couldn’t solve it. I had to write a second script to make the node work.
