First I tried NURBS splitting the front face of the wheel into 3 separate types. 1 revolved circle shaped surface for the centre, 5 duplicated surfaces for the 'spokes' and then another 5 duplicated surfaces for the slopey in bits in each hole.
The surfaces matched exactly but there were horrible gaps and sharp joins at the seams which I couldn't get rid of. I am thinking now I would be better off creating one big, smooth sub-d surface for the face of the wheel to create a smooth almost skin like surface?
I have never used sub-d's before, I would be very greatful if someone could describe simply how they would go about modelling the wheel, I'm not sure what approach to take with it. Do I create a disc then boolean out the 5 holes, or create each spoke individually?
