Thanks for the quick reply.
I don’t know how the software determins the order. All the curves are numbered there. How can I see / check the object table in Rhino? I could check if the order in Rhino’s object table corresponds to the numbering in the laser software.
One thing I had already tried:
I had opened a new Rhino document and copied the curves over in small groups because I assumed the curves would get numbers according to the order in which they are created in the document. I checked in the laser software, but the order of the cirves is still the same like in the original document from where I had copied the curves from. If it would have worked, I would have copied the curves over to the new document one by one and exactly in the order I would have liked them to be cut. But, well, does not work that way
