[Mi...] Posted May 25, 2023 Share Posted May 25, 2023 It happens anytime you change the datums, because unlike a regular Position characteristic BFBP doesn't automatically update your nominals. Open the pattern, delete, then reselect the features you're measuring and it'll be okay. I've gotten into the habit of always filling out the DRF first because we have a ton of patterns.

And do they have to be equally spaced apart, or can they be offset from one another? I have a position callout for a two bore pattern and another one for a 5 bore pattern with the bores offset from one another, so I'm not sure the bore pattern option will work for these.

[Je...] Posted May 25, 2023 Share Posted May 25, 2023 Bore pattern will work for any circle/cylinder feature as well as others feature types. "Pattern" simply means it is a grouped set, not an even distribution/spacing. The nominals are set in the patterned feature definition. Link to comment Share on other sites More sharing options...

If you do the features first, you'll keep getting that dialog box. Link to comment Share on other sites More sharing options...

Hi Jeff, I was told that you can only us BFBP when you have multiple or composite position tolerance callouts. Is this true, or can I use it in situations like the one in the photo I've attached? I guess what I'm asking is: when should BFBP be used and when shouldn't it be used when programming positions?Programming Hole Pattern Position - 3.jpg Link to comment Share on other sites More sharing options...
[To...] Posted June 2, 2023 Share Posted June 2, 2023 Yes, you can use BFBP for a fully constrained position, even if it only for 1 feature. A major benefit of using BFBP is the ability to produce a plot which you can't do with a position.Screenshot 2023-06-02 112344.jpgScreenshot 2023-06-02 112243.jpg Link to comment Share on other sites More sharing options...

[To...] Posted June 26, 2023 Share Posted June 26, 2023 Please sign in to view this quote. Yes. However, I assume there may be a situation where you would want to click NO, otherwise why would this dialog box be necessary. I just don't know what that situation might be.

So, this might be a stupid follow up question, but is it basically asking if we want to fill in this Pos-Tol portion of the BFBP settings?Position Tolerance Transfer - 2.jpg Link to comment Share on other sites More sharing options...
