Hi All, I have a chute i am trying to draw, it moves in many directions so rather than trying to draw it 'on the flat' what i have done is measured it in 'rise over distance' ie. if it is at an angle, what i do is measuer how far it drops, then how much it moves across, then draw it by entering WCS coordinates. All good so far and i am left with a nice wireframe which is good and accurate... but i cant extrude! My general method of extroding is; PE, Multiple, select all lines, join. Then extrude to required depth. I cant seem to do it because i cant line the UCS up with the object. Since it moves in so many directions and has no true 'squares' I cant find anything to lign up with. Any suggestions on how i can either; align the object to the current UCS/align the UCS to the object so i can PE/extrude, or extrude some other way? Thanks! Shaun
