Hello,

At the moment I get a error from the node Geometry.Intersect. The error says at follow: Curve join produced more than one WIRE in polycurve. The script worked perfect on another polycurves but now a tried it on some other polycurves and iI get this error. I have seen that this error is some what common but couldn’t find the solution in other threads. I added the script and the two CAD files I use to extract the polycurves from.

Someone has a solution for this I still can’t figure it out.

Hi Hugo,

I’ve looked into the issue and i feel like there’s something wrong with the polycurve. I think it has a tiny gap in it, but I’m not entirely sure.  
I tried fixing it in your script:

 ![Polycurve%20error](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/9/d9ad17d6c6da75062d06d92961768e3970131dc7.png)

I’ve added the PolyCurve.Curves node and set the listlevels of the geometry intersect node.

Hope this helps!

Thanks man that did the trick! I think indeed the problem is in the curve but thanks again for the answer!
