Group curves and export as dxf - not working

Would like to export dxf-file from ShapeDiver for production with a lasercutter.
To make it easier to move objects around for the people at the lasershop I would like to group the curves.

Am I doing this the wrong way?

In the picture there is 3 export-components.
The top one (without grouping) is the only one working, it will export the two curves.

You are not doing anything wrong, the problem is that we don’t support Grasshopper group objects yet. You can use them within your model, but they won’t be displayed or exported. We will fix this before the end of this year.

Ok, thank you!
