    Constraining O-Rings and such

    Was just making another O-Ring and remembered
    I never got around to posting on this topic. From the answers
    I've read on constraining O-Rings and such, I noticed I haven't seen my
    technique mentioned (not to say it wasn't, but I didn't see it). What I do is
    extrude a surface on the ID in both directions that equals the o_ring diameter.
    Then I usually place an iMate so I don't have to turn the surface back on to
    constrain it with a single insert constraint.

    The best way to constrain a o-ring is to construct
    the o-ring on the origin center (project geometry- origin
    centerpoint)

    then you can use all plane and axis to constrain
    for example you can now use the z-axes to mate-constrain with the tube and the x
    or y plane with a plain of the tube + 1/2 cord-diameter

    Yeah ... but, then again, you have to turn
    'em (the planes/axis') on/off in the assy to constrain 'em. With the surface
    (project the ID/Extrude to length) you can place any kind of iMate you want and
    plop it in without even going to the browser. Not saying any way is better than
    the other, just saying how I do it. Never know who might get some use out
    of it.

    You don't have to turn them on.  Just select
    them in the browser...
