Are there any particular use cases associated with the width types? For instance, why would percent be better than offset for a particular model?
Hi Steve lloopcut ,
As far as I know, Percent is the only one that is fundamentally different and can be useful, when other Width Types run into problems with Clamp Overlap enabled;
For instance:

When working with smaller models Percent is better, because you don't have to deal with the fast shifts when adjusting the amount. Also when you have asymmetrical models percent can sometimes produce better results if you are trying to avoid using weighting the edges.
