I’m almost embarrassed to ask, but why doesn’t it work regardless of the order in which I click the curves. I just can’t figure it out: D
Dear @wadim2011
if you want more specific answers, post the .3dm file.
if it is a cylinder, and red, blue, cyan, green curve are the same, a simple _revolve should do the work.
other suspects are:
_railrevolve
_loft + _matchSrf,
and there is also some great technics using Control-Point modelling…(see Rhino training level 2)
kind regards, -tom
patch also does an ok job of doing such trickeries.
Hello - it seems like maybe you are starting with a relatively ambitious project before quite understanding how the surfacing tools work - I’d step back and make sure you fully understand

if you are looking for a way to close such legs with round endings, consider using pipe, with 2 different radi and caps set to round you will have a fast and maybe sufficient solution for the entire legs.
the conjunction in the middle can be done with blend surface, maybe not too ambitious but finding the right tools requires a bit experience with rhino of course.

thanks i have somehow managed to get the feet with the round ends done by myself: D but now i’m trying to get the conjunction in the middle. It doesn’t have to be exactly like the photo. I probably thought that I would use sweep to rail on all three feet and then use blend surface, but unfortunately it doesn’t work that way. Do you happen to have a simple idea? : D
well i did a very quick build, so excuse the ugly disproportions i am sure you will do a better job 
i would use BlendSrf from one leg to the other
trim it like so
and rotate copy it
you may want to trim a bit of each edge off and blend that with each other for a better look but i leave that to you.
now draw a line from an ortho view and trim a part off
create your alien bubble head and trim a bit off either
now use BlendSrf and finished is your invasionator.
