Hi,everyone!
I want to pick 4 points,the first four points determine the radius of
cylindrical bottom surface,and the fourth point determine the cylinder's
height,so I can use these values to create the cylinder in the right
position,and now I can build the cylinder by picking points but it is in the
place where the origin of coordinates in,how can I move the cylinder to the
right position?
Thanks for help

You could position the actual data with:

or you could position the actor representing that data with:

See the "Transforms" slides here for a little bit more explanation:
