Hole Dimensioning?

Sorry for all the noob questions, trying to get up to speed on the fly.... ;/

Couldn't quickly find the correct tool to dimension holes, and had to resort to putting text leaders on them...ergh!

Looking for the proper tool/command to annotate holes using the the size, pitch, depth parameters of the hole...

Any help would be most appreciated.

Are you serious, or just pulling my leg?!?!

First off, go to your view, use MB3, and click on "Properties". Make sure your view has the "thread" button checked.

Once you have that, go to your dimension toolbar, tear it down, and select "thread dimension". You will hang a thread dimension on the hidden lines that appear in your view. They are NOT attached to the solid lines that represent your minor diameter.

Forgot to mention - you still need to manually hang the depth symbol on. But that's much easier once you get the dimension part worked out. Make sure you have the "manipulators" turned on, under Tools -> Options -> Mechanical Design -> Drafting -> Manipulators -> Dimension Manipulators. This will make it very easy to modify the dimension after the fact. (including add text) You will be able to attach text just by selecting the dimension, and then clicking on one of the red triangles that appears before or after the dimension text.

Appreciate the response...

I've fiddle with that "dimension the hidden threads" widget, and wrote it off as being incorrect practice not to mention kludgy...

Is there truly no way to put a proper hole note in the correct view on a zillion dollar a seat system like this???

It's not an incorrect practice. It's the right way to dimension threads. The annotations that accompany it are a real pain, but that's the way it goes. Catia is clearly geared for FD&T, and not the "old" methods.

Drafting workbench is the weak link in this package. Either you'll have to do it the "incorrect" way, or live with it like the rest of us.

Doesn't seem "functional" to me...but consider me schooled...

Thanks for the info!

You can use "create technological result" and then use "Tap-Thread Analysis" This will give you your thread depth as well as your pitch and thread size.

As far as I'm concerned, there isn't a Thread tool.

You have to use work arounds to get what you and your customers want to see!

Just for fun, try this after you have a couple views:

Insert + Generation + Generate Dimensions and turn on all of the options before you OK.

This will impress the boss!

Kapmc: Thanks. Is there any way to bring that information over to the drawing? That is exactly the type of call out I bet most people would like to see.

Why would Catia have that callout (.250_28 UNF-2B.....)available in the model, but not the drawing?

Thanks,

When you use "generate dimension" this will bring over the thread diameter as well as the thread depth.

I was hoping since the model was able to display the thread specification (.250-28 unf-2b, m8x) information, that that information could be pulled up by the drawing.

I have not found an easy way of doing quit that.
One work around I have done is to link a Parameter with the thread information to the drawing, so that if you update the parameter the drawing information will update accordingly.

I am slowly realizing how spoiled I had become with the features of mid-range modelers. A bit ironic that it came to light by using a high-end product... :crazy:

Mid range modelers are good for what they are good for, and high end in their own rite. There is lots of nice stuff in cheap software. Some of it costs a lot of money, but it's geared towards specific customers with specific tasks. A guy using solidworks in the machine shop thinks it's the cat's ass - and it is, for what he does. But I get calls every week from someone who can't do something in SolidWorks or Pro/E, and they need Catia help.

To say that a mid-range modeling package is better than a high end package, means you are using both of them somewhere in the lower percentile of capability.

I didn't say that...but I guess it's more fun to speculate on what percentage I utilize my software rather than conjure up a useful hole annotation method... ;)

Sincerely though, thanks again for the help.

No, Catia doesn't do drafting well. I pointed it out earlier, and I definitely won't claim otherwise.

Small consolation, though - it makes the prettiest drawings, and best looking PDF's on the planet. Is that the least bit comforting?
