I know it can be done in Solidworks
I don't think there is any functional difference between SWx and Inventor with regards to this geometry.
Do you have a close up picture of an actual part you could post so that I don't have to make a trip to the hardware store?
Take a look at the original file.
or do you mean is it correct as a SHCS.
I originally read this as is this what the OP wants.
In any case, I don't think a thread can be run right up to the clamping face.
For a manufacturer I think they want to model exactly as produced.
Okay, I see. I think McMaster-Carr uses SolidWorks. Attached is the closest I could find on their site with a two minute search. I know the head is incorrect.
Seeing as our camera takes terrible closeups, this is the closest I could find of a T17 point showing what I mean regarding how the thread diminishes near the point.
Here is a very crude quick screw ex. Sometimes you need to think outside the box.
open the file and drag the EOP marker to the bottom. I know, I know the point is not correct. But you will see how to do it.
Yeah, that's really, really close, and, functionally, it's the closest I've seen. Unfortunately, our company stresses the importance of a very, very sharp point (otherwise, "you may as well be trying to screw in a nail"), and that's where I'm encountering the majority of my problems. I'd thought of doing 1 revolution, changing the pitch, another revolution, but then I'd just end up with a stair step.
And I haven't even begun on the Aster threads yet. Maybe 2D will be the way to go, as much as I hate to admit it. I think a well modeled graphical representation, when handed to a newer machinist, can be an eyeopener for them and give them a basis of comparison.
I made that in about 2 minutes. I don't have your specs what you needed and I don't have the time to do the work for you. Just wanted to let you know if you put some time on this you can make this screw. With some planning you could make an I-part and cover every screw size you would need.
Nor would I expect you to do the work for me, and, as I said previously, the problem exists in the tip and how the coil wraps without the pitch changing. Once I figure it out, I do intend to make it into an iPart, but until I can figure it out with a true point on it, it just becomes a backburner.
But believe me, I do appreciate your example and I intend to, hopefully, work with it a little bit today to see if I can get it to adapt to what I need.
