Hard to imagine having fun creating large library of nuts an bolts
over long period of time.
I had made screw and nut family table parts and squized as much DIN/ISO standards in those two. Ive created it basicly to make my life easier because all library parts i could get my hands on where with either cosmetic thread or with parameters which were not compatible with my company drawing tables.Not to mention having to translate parameters that could be used to our language from those library parts.
We gona probably soon let ppl download them from our website so others can use them too.
Dan,
Has anyone designed these things? Probably most of us have. Also, nowadays, folks use libraries that have already been created for them within their organizations or from vendors. Years ago, around Rev. 16 I did a contract job to create a Family Table library of all of a company's fasteners including castle nuts and other odd things. Anyway, for the fun of it, here's a bolt.
A couple of tricks to make it more realistic. (1) Put an appropriate chamfer on the end of the bolt
before creating the Helical Sweep which generates the thread. (Cut highly preferable to Protrusion.)
(2) Sketch a 60 degree triangle for the thread section beyond the end of the bolt so it will easily cut
through the chamfer. (Use Mirror in Sketcher to make this easier.) (3) Use the abrupt flat end of the
cut as a sketching plane and Use Edge to capture its triangular shape, add a Centerline at some
distance away from the bolt axis and then create a Revolved Cut to feather the thread more naturally.
For what it's worth.

Oh, and for the head chamfer you can use either of two techniques. (1) Create a hex head, then
add a revolved cut for the chamfer, or (2) Create a cylindrical head, use a regular D1XD2 Chamfer, then
a hex cut.

Once, for fun.But after 10-20 turns trying to position nut on screw i lost all interest. You can create tiny extender mechanisms with 2 nuts and screw or screw and long connection nut.

Try these: A quick and dirty Tri-lobe screw and a Smalley "multi-level" wave washer I did for fun. didn't bother to get fancy on the rendering as the wave washer I did about 12 years ago. And, yes, that's perfectly cylindrical on both ID and OD (unlike if you used points to define the trajectory curve) and is created using a single trajectory. The bottom pic is a sink drain part I did in '96 when I first learned Pro/E. It's brass tubing where the thread is rolled into the tubing, so there's a threadform on both the ID and OD. Pro/e is good at removing or adding material, but not about displacing it.
