Thanks Scott, I'm still not experienced enough to understand all your suggestions yet, but I'll get there. Your examples are really cool.
A baby next step for me would be to figure out how to add a subject to any dish circle, or better yet, to any 'dish', I recall seeing a vectric forum tutorial (I think) on that. I did a practice concave circle (for a future ulu cutting board project) earlier, and at least the circle shape would work better for a log cookie, but I don't yet know how to add/merge the subject to the dish.
But I even like better the 'exaggerated model offset shaped dish' (not sure I saw a Vectric tutorial on offset dishes?? I have watched most of them once). Does one just pick a large offset value, but then both the Rough and Finish offset values would have to be equal?
I now notice that my roughing offset value was 0.2 inches whereas my Finish offset was 0.05 inches and maybe that difference also accounted for the rough base, seeing as the BN finishing bit didn't then cover the same territory (I shortcut it, inadvertently). Thanks.
