Hello,

The screw thread video is now available online at Vimeo:

http://vimeo.com/30765016

It's not perfect and the production is a bit rushed and not as polished as I'd like, I'll try to get better over time. Comments and suggestions are welcome.

Hi OSTexo,
No Critiques. Very nice.

A comment could be that ShrinkTrimmedSrf can be immediately run on your solid. No need to seperate and rejoin.

Thanks, Burr

Hello Burrman,

I didn't know that, it will go into the next tutorial. Do I just run Alt+S after selecting the solid? Thanks.

That's awesome OSTexo, thanks very much for producing this!

I added a link to it from the MoI resources wiki page as well.

Hello,

Thanks for the info, that will save me some time. The video took me a little longer than expected since I didn't use any templates and built everything up from scratch including the sound effects, and I'm by no means a pro when it comes to After Effects and Premiere Pro.

Hello, Frenchy Pilou,

I agree, I might break up the tutorials more in the future. Also remember is am a relative amateur with MoI so it takes me at least twice as long to accomplish tasks, and speaking about them slows things down, but I think talking about the procedures helps with the learning curve. Perhaps break down into curves and then solids modeling?

Thank you very much OSTexo! Your long spent time formulating this tutorial was very worth the wait.

I feel like I just completed a trek to the guru on the top of the mountain. :-)

That was extremely informative and drawn out on a good pace so that most folks could see what happens between point A and point B.

I encourage your future tutorial endeavors.


BTW, do you have a link to a site or official chart for specs on those standard spacings, pitches and angles you were referencing?

Hello,

This is the link I worked from. I am coming to think threading is all about tolerances, so rather than be confused by all the numbers on various manufacturer sites I used this for the reference. Assuming you're using UTS or ISO Metric threads, which is most of the world apparently, you can make any of those screws just knowing the pitch. I really hope my interpretation of this diagram is correct. If not please let me know.

Hello,

Thanks for the thanks, do I hear rumblings of perhaps trying a Twist command screw thread?

Tried that a little. The Twist command seems to add a graceful swoop to the faces of anything twisted - as the logic of that mechanism dictates...

Sweeping a profile on a helix is the supreme way to make threads so far.

Hello,

Great reference, thanks. Using this information could a partial thread calculation be made to determine the tapered helix parameters and to accurately place the secondary helix on the bolt cylinder? I know that NSF type stuff specifies this as 3/4" rise per 12" taper, so it's easy to know exactly where the threads are going to leave off cutting the cylinder, but I can't seem to find out the parameters from UTS or ISO Metric. I also can't find the depth of those arcs at the crest and root of the thread, do you have a reference on how to calculate that? Thanks.

Hi Mike,

> mechanism dictates...

Only when "Limit to axis" is checked - that acceleration swoop is what makes it possible to twist only a limited section of an object and not have any odd hiccup where it transitions into the non-twisted part.

If you turn off "Limit to axis", then Twist will generate a totally regular helix effect, and actually any lines parallel to the twist axis will become a regular helix in shape.

So it could be a good fit for threads - definitely worth a try!

A little while ago I had thought that Twist wouldn't really work so well for this kind of thing where you'll probably be doing quite a lot of turns, but it actually seems to handle it quite well. By the way, you can type in stuff like 5*360 for doing 5 full turns for the twist angle.

- Michael

RE: Threads,
The new Twist command is pretty cool for doing quick metal screws.



Instructions included in the 3dm file.

Hello,

Thanks for the addition to the wiki Michael and for the compliment, I really appreciate it. I think there probably is a way to make a screw thread very quickly with the Twist command, but I'm letting the smoke out of my brain trying to think of how to get a flat flank to the screw thread.

I think your tute was well paced and thought out. I think it is easy to follow and grasp. Commonly, tutes are done by experts who know all the nuances and tricks/ins and outs and "Baffle" newer users with whats going on.. Old hands may get impatient, but targeting the old hands may make a lessor, or typical tutorial. Congratulations!
