Re: Coil
I would, but the spring does not touch the screw. The spring's diameter is about 1/3 larger than the screw. That is why I am having troubles. Thanks for your reply though.

But I've had trouble using a Tangent with a swept surface so I don't know if it will work for a helix. You also may have to try both an inside and an outside tangent (the two buttons on the lower right of the dialogue box). I can see a good arguement for using either one. It helps if you have the constraints set to preview, so you can see what you're going to get before you are committed. Kevin's method may work as well. I've never played with helixes in Inventor so I'm not sure just how they pickup constraints. The thing about CAD systems is that they never quite work just exactly as you want them to all the time. So you are constantly having to learn "work arounds", most of which you wind up figuring out yourself. Then as soon as you start to know how to do everything you need to do, they roll versions or change you over to a new system and you have to start over again So keep trying until you make it behave.ChrisH |

Re: Coil
Every cad package I've seen has problems constraining helix(s). I hate to say this, but if nothing already mentioned works, you may be best off just eyeballing it.
What are you trying to do? There may be an easier and more efficient way of doing it, expecially if it's a cosmetic detail. Greg |

Re: Coil
All I can say is try to use a work plane, or axis, although I havnt really had much experiance with the coil option in inventor, I've only modeled springs 3-4 times, and I havnt had to do much constraining.

Re: Coil
It's been a while since I've used inventor, I've been busy learning solidworks in college this year... Could you make a work axis in the coil part drawing and then constrain the screw to the work axis?
I think that's your only real option.... I think a tangent constraint will just horribly confuse inventor, since the coil would have to be tangent at several points.... |
