Meshes Q.s: Unfolding; Turn curved mesh into squared? 2004-08-16 - By Anthony Ware
Back
Kris,
This is really quite trivial to do, but requires some tedious work on your
part which you will no doubt baulk against.
Choose a face of the object on the required latitude or longitude, enter
point edit mode and repeatedly do a "slice object by selected line/plane"
along the chosen face. You can then further point edit the result, removing
all none longitudinal or latitudinal lines and faces, resulting in a mesh
with all 'lines' along the required latitude/longitude.
