create your “cube” with _loft of two curves.
use option SplitAtTangents = No
(or other workflows to get a single surface)
_unrollSrfUV
(check this forum for Info on developable surfaces)
construct / draw the lines in 2d on the unrolled surface.
_flowAlongSrf
to map them back to the “cube”
(also check for _flowAlongSrf there are a few aspects to care of)
hope this helps - kind regards -tom
