In the attached, I have a sweep path and several cross sections. Because the cross sections are tiny compared to the length of the sweep path, I tried grouping them to insure that I always grab them all.
WHen I do the sweep1 using the group Rhino the cross sections in a bizarre order that does not follow the sweep path. Why does rhino choose this ordering and is there any way to change that?
