Rhino sweep problem

Hi! I try to use the sweep command but it fails and ı do not understand what is the problem. ı try twist the profile and make it a bit smaller on the other edge.

make sure to set proper start / end points and directions

not sure - what do you expect ?
maybe post a sketch / screenshot ?


thank you for your attention, when ı pick all the lines at one the sweep happened. otherwise, an exploded object occoured.
