Hi,
I'm in the process of modelling some steel work for a client. The object has been scanned by ourselves and imported into Vectorworks. The steel work is question is curved and undulates in height along its length.
For modelling I started with a NURBS curve, with points picked only the perimeter of the steel, I then extruded along path to create the surface. All of this worked nicely and I have been able to create the model needed.
I've now been asked to mark out the centerline of 2 of the lengths of steel. I can't seem to work out how to do this, do I need to convert the NURBS surface into another component for it to work.
I can re-create the original NURBS curve but I am pretty sure that I wont be able to simply offset the line.
Do you have any suggestions for how to tackle this?
Many thanks
Steve
