Isotrim not working on all surfaces

Not for the non-planar surfaces, no. Even divisionings on curved surfaces is exactly what Rajaa’s Panelling Tools are made for, so I would suggest working with those?


I also just want to be careful about making any suggestions on how to divide the curved surfaces here, as in this other thread:

it would seem they will not be vertically planar? Or it is not clear. In the case that they are not, I would much sooner use UV isolines of the original surface than devise new vertical ones.
