Creates curves-on-surface from existing curves and surfaces by projecting the curves onto the surfaces.
Curves-on-surface – The projection results in curves-on-surface.
Curves – The projection results in free curves.
This option is only available if Create is set to Curves.
If this option is checked, the edit points from the original curves are projected on the surface(s), and the projected curves interpolate them, resulting in a similar number of spans.
If this option is not checked, the resulting curves will be better approximations of the projected sections from the original curves, but will likely contain more spans.
Save the history of the projection for later editing. If you turn Create History on, you can modify the curves and surfaces that were used to create the projected curves, and the projected curves will update. See .
