Cannot construct datum systems in all stages


Recommended Posts

Hi All,

Does anyone know how to resolve the following error message?

'The chosen datum system has different degrees of freedom in different stages'

My datum system is fully determined, having no DOF left, nor is there any rotational symmetry.

The stages contain some 30 sample scans of nominally the same product.

Once a certain stage is selected it will correctly calculate its datum system, but at the same time it will render all other stages' datum systems invalid. ?

GOM cannot calculate all datum systems together.

Anyone having a clue?

please contact your local GOM partner and provide the project for us if possible. Most properly we have a deeper look onto your project to give a good answer. Of course we can sign an NDA, if needed.


Best regards
