I agree with the Helix solution... Additionally, if you want to draw a bent spring, just make a single twist helix, copy that from the top to bottom or bottom to top and rotate it. you can do this for as many turns as you want, then since the helix is a spline, use join to connect them. Sure this is nearly as cumbersome as the "torus" solution, BUT! If you want a wire shape other than round, you can copy your shape to the end of each helix and sweep them along the path of the helix. Oh yeah... the "Magical" thing about this is, then you don't even have to rotate the shape you want to sweep... That's right! it will automatically just rotate it per the angle of the helix... I found that out the hard way after modelling a slinky. First I tried joining all my helii, but my PC didn't have enough "ooomph" to handle it, so I opted to do it segment by segment. I was puzzled for hours as to why my segments didn't match up, and finally tried NOT rotating it out of sheer frustration. Bingo! it worked! Try it! it's fun!
