Hi ironsightdesign, that's just a limitation of the mesher. Each surface gets initially meshed independently with a set of quads in its own UV space. That's because the mesher has to deal with all kinds of situations like 2 surfaces that meet up without anything in common in their UV layouts like this for example:



So basically it's the normal case that UV grids won't align with each other naturally. When 2 surfaces meet up that share a lot of common characteristics then it's possible for them to get lined up quads but it's a special case. Can you post your .3dm model file that you show in your screenshot, does it possibly have something cut away from it somewhere?

Note that having quads lined up or not lined up won't really make any difference with regard to rendering.
