rock, with a plugin of my own. I did cheat a little on the u-shaped 12,3,12 set. I created a run of 12 then copied,rotated and moved it into position. The run of 3 was then rotated and moved into place. The elliptical stairs required nothing additional to be done. The plugin has a u-shape option but it assumes stair runs stop and start at a landing.
well which plugin r u using? 



I already have this plugin, what i'm looking for is free motion restricted to xy plane.
video tutorial please
well I have windows xp 32 bit and 4 GB of RAM. i'll have to spend some money
