I'm having a difficult time figuring out how to properly model a screw thread around the point of the screw.
I have gotten the coil to taper to the point, however, I'm unable to get thread to terminate properly.
Essentially, the pitch remains the same as it moves down the taper, but the major/minor is diminishing until it terminates cleanly at the point.
Any help or direction would be greatly appreciated.
Find the red End of Part marker in the browser.
Drag the red EOP to the top of the browser hiding all features.
Save the file with the red EOP in a rolled up state.
Attach the file here.
any reason you are modeling the threads versus just using the thread tool in Inventor?
Modeling a real thread versus just the cosmetic representation that the thead tool/feature will just slow Inventor down some..
Yes, there is an actual reason for it. I work for a company that for years has outsourced their prints or simply done them in 2D. They want to come up to speed and keep up with their competition.
Seeing as we're a company who produces manufactures screws, it's fairly important.
So you're talking just one screw per drawing, not an assy with many multiple instances of screws. Just to clairify.
Also best answers come when you define which version of IV? you are using, as in (2012). This becomes a bigger thing latter this month with new version out, some guys wait to update for upto around 6 months.
Yes, it is one screw per drawing, not an assembly with multiple instances of it. I am currently using IV 2012 Pro.
And any extra information you need, feel free to ask. I can't figure it out, and I can't expect anyone else to unless I tell them what they need to know, and since I don't know what to do, I don't know what to tell.
Just a suggestion..
Are you planning on making this an ipart?... (So you can cover all screw lengths in one ipt file) You could even cover all sizes/lengths of each type in one ipart factory (like #2,#4,#6,#8... 1/4" long, 3/8" long,etc...)
With some creativity 1 drawing could cover every length/size in 1 drawing versus a drawing for each size and each length.. (A table could be put on there and you could just dimension the length as "L" and then call out the specific "L" dimensions in the table,etc..)
To be completely honest, I've not done much work with iparts, so the concept of how to do it is not something I'm familiar with.
But yes, if I could get the thread to model out properly, it would definetly be something worth considering. The leaner, the better.
And, if it's a completely lost cause and not even a possibility to model, I'll just tell them that and go back to doing it 2D. I know it can be done in Solidworks, but my experience in it is zero.
And even in looking closely at our sister companies prints, the thread is maintaining the same major/minor throughout the point, it just looks like they're better at hiding it.
So maybe *sigh* it has to be in 2D.
