Global Variable controlling thread depth

[DanPihlaja]

So, I have a hole wizard that is making 2 holes.

The holes are 7/16-20 thread. I wold like to control the thread depth with a global variable.

When I select the hole, I can see the dimension that controls thread depth.

When I double click on that dimension and assign its value to equal a global variable, it doesn't update.
It shows that it has an equation, but it still uses the value from the hole wizard.

It even shows that it is assigned in the equation manager:

Unfortunately, the hole wizard isn't smart enough that I can assign the global variable from right inside the form.

I can't get it to work.

OK, so I was successfully able to use a regular cut and then manually inserting a cosmetic thread.

But when I edit the cosmetic thread, it isn't greyed out like other forms are.

In fact, if I then change it, it overrides the dimension until I manually re-edit the dimension (without actually changing it).

Its like the form and the equation manager aren't speaking to each other.

This is obviously a hodge-podge of programming just jammed together without verifying that it works together. *sigh*

Its not a game-ender. I was just wondering if it could be done.

Yes. It can be done. Manually. In the drawing....

Can you double-click on the dimension to bring up the Modify Dimension box, enter the equal sign, then select the global variable from the drop-down?

I'm curious as to how you got the hole wizard to add cosmetic threads.

Also, you're selecting the cosmetic thread, not the sketched geometry. Might this have something to do with your difficulties?

At the very bottom of your hole wizard feature, click this:

Interesting, mine creates the cosmetic thread, but nothing displays on the part.

[SPerman]

It doesn't show up if you have annotations turned off.

Other than what's been said above. If you're asking how to show the threads in the model window, this option should be checked in the document properties.

[jcapriotti]

I usually turn on the Shaded cosmetic threads but leave the other off since it can get busy in assemblies with little dotted circles everywhere. It's better than it used to be since they added the global annotation overrides though.

That works for the hole depth, but not the thread depth.

[AlexB]

Yeah, I tried to replicate this with 2018 SP5. The global variable changing does not cause the hole wizard thread to rebuild. I can't even get it to update by editing the feature after modifying the global variable. Not sure why this specific scenario is so broken, good find!

Yeah, that is the same problem that I am having.

I forgot to mention that I am also using SW 2018 SP5.

Thanks for looking into it!

So, I broke down and asked the same question on the 3DSWYMP forum

Not sure if this link will work, but here it is...

First off, how dare you?!?
With that off my chest..............if only they would allow "Up to Surface" for threads, AND a variable for thread depth.

Another thought: have you tried Advanced Hole? I have to confess, every time I try it I get lost in the interface and just give up.

[JSculley]

I replied to the SWYMP post. You can link the cosmetic thread depth to a global variable with no issues in 2021 SP4. So, somewhere between 2018 SP5 and 2021 SP4 the problem was fixed it seems.

No, I haven't tried advanced hole. Advanced hole makes no sense to me whatsoever.

Advanced holes are yet ANOTHER feature that is 95% complete. Advanced holes are great for "Complex" holes. So for anything that has more than a couple features I use advanced holes. So say I have a thru hole that is tapped thru, has two countersinks on one side and a counter sink on the opposite side you can build that hole all in one feature with advanced holes....but when you get to the drawing trying to get it all into a single callout ends up being a challenge at best to a complete nightmare at worse.

So you can do this in a single feature.

But in order to get the callout on the print you actually have to manually fill the call outs for every item.

And in order to actually make it parametric you actually have to put in all the callouts like <MOD-DIAM> etc etc and they are not all the same as regular holes....so it's a bit of a PIA.

This is what you get if you DON'T fill all that out if you put a hole callout on it.

Helpful, am I right?

So would it not have made sense to use similar or the same callouts as in the hole wizard and just filling each feature? So instead of putting in "Nearside Counterbore" how hard would it have been to put in the proper code to get diameter, size, depth for each level the same way it's done in the hole wizard?

This is exactly the part that makes no sense to me.

This seems to be Solidworks MO. I wonder if their program managers and developers are all non medicated ADHD. "Hey I have this really cool idea....Squirrel" There is SOooo much in this program that is not quite completed and never seems to get there.

Advanced hole should have been just part of the hole wizard. You have all your normal stuff and then an "Advanced" option where upi get to "Build a hole" and then throw a hole callout on it....let's just say it's not that.

I had a co-worker came up to me today asking me how I'd do a hole similar to the above. It was something like a tapped hole thru with a couple other features. I told him to play with advanced hole and the play with just using hole wizard and doing cuts for the other feature and see which one "Sucked less" to him

[SPerman]

It is as if they hire a different programmer for every feature, and then forbid them to see how similar features are implemented.

Honestly, it would be easier and more accurate to use the hole wizard 4 different times in the same location

Then add 4 separate hole callouts to the drawing, then add a single dimension and link all the hole callouts inside that one dimension, then hide the 4 hole callouts.

Then there is not messing with what the callout is supposed to be.

(this is what I do now)

If I have to dimension something like this, I am creating a section view and dimensioning it there. Maybe it's because I'm not trained draftsman, but I don't trust a machinist to properly interpret a stack of 5 diameters and depths. (Of course in this day 99% of the programming is being done from the model, so the confusion should be at a minimum.)

I agree and for the most part what I do. When I do that the advanced hole wizard actually works perfectly. You can do a really complex bore/hole and then just manually dimension it. In the model it's a single feature.
