Reporting True Position Without Size?

[AaronF]

I'm fairly new to PC Dmis and I'm attempting to report true position for a large number of threaded holes. I can't figure out how to turn off reporting the size of the holes which is irrelevant for threaded holes as they will be checked with a thread gage. Any help would be appreciated.

Thanks,
Aaron

Right click the Size header - Hide Selected Labels.

This will only hide it until you reopen the program. If you'd like to hide it permanently, Right Click - Edit Object - Deselect all Checkboxes - OK - Right click empty space - Hide selected labels. The next time the program is opened, there will be an ugly blank space where the size used to be. To completely fix this, use a custom report template.

Send me a message with your email if you'd like the template. I can't upload it here because it's 38kb over the size limits

Thank you, that's basically what I was looking for. It's odd that there's no way to just not tolerance the size.

If you use legacy you just delete that line of code in the dimension.

or don't select it when creating the dimensions...

You could also construct a Cast Point from the circle, or a Cast Line from a cylinder and dimension it that way.

Have you tried RFS and see if that will allow you to not report the size?

I use legacy.

I'll fill out the T.P. dialogue box & click "OK". When the T.P. code is in my "Edit Window", I highlight the line that shows the diameter and I delete it.

There is no way (that I know of) from within the dialogue box to turn off the diameter when reporting T.P.

Funny you brought this up, I was literally just programming some threaded holes and doing this prior to logging onto the forum.

I have never used legacy. I would like too. The class i went to PC-DMIS for CMM didnt talk about legacy at all. Only Xact. I know where to turn it on! So that's a start i guess.

There is a huge difference between the two methods. Just be careful!

When you use XACT to report GD&T, the Datums you select in the DRF Builder are looked at by PC DMIS and the software makes an alignment IN THE BACKGROUND (you see no code) and uses THAT for the reporting of the current dimension. If you have a sound datum structure on your blueprint, this can save you a lot of time by cutting down on the amount of alignments you'd have had to make in order to measure your part.

In legacy, you have to build the alignments you want based off of features you measure and then use/recall that alignment (AND use correct workplane) when you're measuring as well as reporting features relative to that alignment.

I use Legacy because I quite commonly get prints where the GD&T "isn't quite right".. or where if I used the exact DRF on XACT, the result I'd get wouldn't be quite what I want (maybe the print says ABC but the view I have to report is a rotation of that, so the XY values would be off & the operator would be confused if I used XACT). It is a little bit more work but by doing this you can control what your program is doing 100% instead of allowing PC DMIS to make it's own decisions. Lgacy also looks much better (IMO).. You can actually see code in your edit window that makes sense (as opposed to XACT where you have to F9 it to see what it is).

In Xact, the last tab of the dialogue allows you to deselect things you don't want to see, like the diameters.

If you are doing more than one feature in the dialogue, there are multiple lines to uncheck things in on that last tab, one for set and one for each individual feature. You have to go through them all to get everything.

I commonly still get issues with Xact where it does something weird with the datum structure (predominantly when the datums are square to each other), and I create an alignment as shown in the FCF and then output legacy.

I also have a lot of parts where the engineer defined -C- to control rotation, but offset it 12° from the X axis. Xact will report the X and Y locations with a rotation straight to -C- like the FCF says. That information is useless to the guys on the shop floor if they have to adjust something. So, again, Legacy.

You need to learn GD&T for the FCF set up and use Legacy as a tool.

Sometimes Xact is gorgeous and eliminates all customer questions, sometimes Legacy is the right tool. Fill up your tool box!

Could someone please help me with the following. Attached is a Xact output with datum modifiers as per print. The position of the feature is fine but the datum features are showing red. i know that it has to do with the datum shift, but is there any way we can deselect them or at least have them green. People don't understand that this is not a a reflection of the position of the feature but added information on the datum modifier.

Please start a new thread with this issue, giving us an example of your print/geometry and your alignment structure.

You can remove the sections from the report, but you may be letting a nonconforming part go. Let's look into your issue further before masking the report.
