thread run-out
thread run-out
(OP)
Hello out there. I designed a fastener in 3D with threads. The threads worked out great but now I'm stumped. How do I create the thread run-out? Does anyone have tips on how to achieve this? Even better would be a sample 3D model to show me how. Thanks.






RE: thread run-out
There is an shampoo bottle example from the Advanced Part Modeling course. They model the run-out by revolving the thread profile at the end of the thread. Your reseller should be able to email you the shampoo bottle.
If the run-out you modelled is somewhat complex, then a revolved feature may not be enough, you may need to create a swept profile at the end of the thread.
You may also want to look in the SolidWorks Model Library, there are a few examples of threads in there, although I could not find one with a run-out per se.
Cheers,
Joseph

JNR,
He maybe in a company like I used to be where they wanted detail out the ying wang. If that's the case then he will need to make detail threads.
But if he doesn't need too, then you "wilton" you should do like JNR says. Don't make them. Make fake threads by making a revolved cut and linear patterning it. If you need an example let me know and I'll upload one to my site.

1) You could make the body of the bolt
2) Produce the helix for the thread of the bolt. (Make the thread rev longer than you need too. see next operation to why)
3) When making your profile and offset it from the beginning of the helix. (Offset from where you start the cut-sweep of the profile so that doesn't start cutting for 1 revolution)
4) After the profile has been cut. Offset plane to where the thread stops.
5) Start a new sketch and make it so it runs off the part.
6) You can make it a helix if you need it to totally correct or you could leave it like it is, since it is a small amount.
7) Start a new profile sketch and do a 2nd cut-sweep.
If you need an example of this let me know and I'll make one and give you a link to it from my site.

I just tested what I told you in the previous post (I was sure it would work, but just in case). Post your email and I will send you the file. (2.57 MB)

Here is a link to my site for a bolt made with 2 configs. One Config is with the above mentioned Runout and the other is with the fake threads, also mentioned above.
IHTH!

Sometimes a guy just has to sit back in awe at what Solidworks can really accomplish. Thank god for the nerds. They really make life easy for me. :)

With any luck, this software will let me retire before I'm thirty. If that's being a nerd, I guess I'm all for it.
RE: thread run-out
I meant no disrespect. I just want to say thanks to all the talented people, including programmers, that make our life a little easier. Again, thanks to everyone and I really dig this site!!!
RE: thread run-out
Scott, glad you got away from the detail nerd that ruled your previous employer. Nothing ticks me off more than agruing with drafting managers for hours over "filled" arrowheads and crap like that. If it is good enough for ASME Y14.5 it is good enough unless there are specific extenuating circumstances!!
Anyhooo... simplification where appropriate can be a real time saver. For example We have a lot of heavily finned cast chassis. We have to model the fillets for good reasons. But by putting them folders and having a "speed" configuration with them suppressed really speeds things up for everyday use - specially when you have an entire aircraft installation open.
