Certainly, that can make sense for those particular cases, although it may need to have a pretty high repetition count for it to make a very noticeable difference.

I'm sorry I didn't say in a better way that my comments were not really targeted at you, more at others who could easily view this as a tutorial on how to best create surfaces in general and then spend a lot of time doing this on every single object that they create.

A kind of hybrid approach for this type of object shape would be to offset just the generator curve and then revolve that along with the original curve, that will make a lighter surface than the one that uses surface offset since it will only have the offset density in one surface direction but still give very high accuracy.

In the future it might also be possible for MoI to make procedural offsets rather than generating fitted NURBS surfaces for the offset command, one reason it does not do that currently is so that all surfaces can run through a single general display routine rather than needing to have special cases.

Hi Michael and good morning.

> I'm sorry I didn't say in a better way that my comments were not really targeted at you,....

Michael, first of all I want to say you that I never had any problem with your comments on my posts in general,
and also regarding my "case study" !! :)

I always greatly appreciate any of your suggestions and I value them a lot.

These experiments are clearly my own personal practicing, and I never thought to tell anyone : "Hey guys, I've found the perfect modelling technique! Follow me!".

I want simply to become more skilled in Nurbs modelling (curves and surfaces),
and if someone thought that my results are good, I will be happy to share them.

This is exactly what I'm doing. Working first of all on CURVES.
But not limited to the Revolve situations. Often I need offsetted surfaces but not simply revolved ones.

> In the future it might also be possible for MoI to make procedural offsets...

This is really a GREAT news!!

Thanks again for all your suggestions and best wishes for all.

I'll keep doing experiments on other "case study for a lightweight modelling" :)

Best,
