I got stuck on tutorial

[vitamin]

I'd imagine that one reason someone would say this would be the fact that there is a difference - in both size and shape - between smoothed and unsmoothed mesh.

I think that it's exactly what Glen Southern had in mind. I just watched a video tutorial about modeling a car using Modo and that is a quite good example of this issue. If you watch section 2 of this tutorial (which deals with creating a wheel) you will see how the modeller switches on and off all the time between the smoothed and normal view.


p.s.
Thank you oort for posting those YouTube videos here.
