Create object like mobius strip is simple, and should be divided into separate operations.

good tutorial, BUT you could specify for the beginners (with surfaces), that when extruding the second surface on the second half circle, you may NOT project the line, but construct a new one and dimension it, otherwise you will get just errors or a reference dimension that couldn-t help you finishing the formula or making the Sweep.

Não consegui...
não entendi o modo que você chegou na seleção da curva e no (Tools-> Dimensions command) estou usando Creo 2.0.
Você poderia disponibilizar o modelo 3D nativo para os iniciantes verificar.
obrigado

Hi, I have tried this, but I am not able get step 12 & 13.
When I rotate using Z axis by 180deg, it's not mating with the existing surface.
