You should be able to specify the name of your coordinate system using the RoboDK settings button in Fusion:

You can follow these steps:

1. Select the RoboDK Settings button in Autodesk Fusion 360
   
2. Select theBasic Settingstab
   
3. Enter Ursprung in theReference Name, or whichever reference you prefer
   

Hi Albert, thanks for your answer.
As far as I can see this has no effect on the robot program itself but only on the position where the toolpath is located after import.
I want to generate the robot program with respect to an other Ref Frame than the .nc file refers to.
