Hi,
i store my surface control points internally in microns. Is there a way to scale/convert it to millimeters? I knot i just can scale all the control points with 0.001, but is there a nicer way?
If you change the unit system of the model and you want you geometry to scale with the change, then this is something you will need to do on your own - the openNURBS toolkit will not do this for you.
