How to draw threaded holes

[Hertz]

Is there something in X7 that can draw a threaded hole? Or do you guys just draw the tap drill size and specify it needs to be threaded? I'd like to be able to draw the thread in the model except I don't know how to draw solids. Only surfaces.

Almost always just draw the minor dia

Drawing threads just makes your file size huge

Ok thanks. But when you actually do draw one, how do you do it?

Draw the thread profile and use solid swept around a helix.

Great. thanks a lot.

I been cheating lately when I want a thread, I just go to McMaster Carr, download the fastener I want and do a Boolean on the solid.

Great cheat/tip

Cheater !!! :old forum cheers:

I always draw both the minor and major, so I can contour the major for a chamfer otherwise I have to use that maths stuff and I don't like that.

If you download the SolidWorks file from McMaster you can open up that sketch that it was created with and see the entire process used to draw the thread.

I've done it out of curiosity in the past. It's pretty envoled and take more effort than I'm willing to put into each and every thread that I need but at least you get the idea of what it takes.

I believe you can use the same process in MasterCam.

Yeah, you can actually draw them, but dayum it takes up headroom in your system. Completely unnecessary almost all the time IMHO.

It can be done as noted, there absolutely ZERO reason to do so, you gain nothing but a bloated file

 

If you have a part with several models threads, your system will come to a crawl quickly

 

I draw them as "reference" I model the minor Ø and create a dashed line to represent the major Ø of the thread

[Hertz]

Awesome. Appreciate the responses fellas. Good to know.

I use solid boolean and solid screw files from McMaster Carr as a tool

I remember something about this that Autodesk said when they launched Inventor - you model a thread and it throws a raster image into the hole by memory. So it looks like a thread from a visual point of view, but is only a visual.

Solid works does the same thing, or can, it gives you a couple of options of how you want it displayed

I thought Autodesk were the first and made a big thing about it - also I thought it was all patented.

Still, I spose it's all getroundable

I find preaty easy in SW to use the sweep to create threads and have done it in MC the same way but SW handles that part easer.

The only reason I ever found to draw the threads, we had a job a couple years ago that had a large thread in the middle, and it had a 1 deg tolerance on the entry angle to the thread. So I drew in the thread so I could verify the threadmill op.

That's usually the only situation I draw them. Or if I have some big thread form and I mill it using full 4th.
