Offset curve problems

[Dmitry_Korchemny]

Hello everybody!
I’ve created solid and with node contour (ex) I’ve got curves on inner side of my solid, which I’m using as the input curves. However, I’ve encountered issues with generating offset curves and currently lack ideas to resolve them.
For example, both the standard ‘Offset curve’ node and the Pufferfish ‘Offset curve’ node didn’t produce the correct result.

Rebuild them.

As @Quan_Li said, rebuilding is working fine. The problem seems to be, that your input curves have some additional information that were made up when you first buildt them and that now leed to a failing offset. By rebuilding them you will only feed necessary information to the offset curve component.
