FCF question

FCF question

FCF question

(OP)
I want to add a feature control frame with the FCF button. I want to add flatness and straightness in the same row in Nx7.5.5. No success only one characteristic is offered- Works as designed? or did I miss something? Please help...
regards

RE: FCF question

Is this what you mean:



If so, rather than using the Feature Control Frame function (which tends to enforce the selected Drafting standard) use the general Note function instead.  Below the text editor window, simply expand the Symbols section and select 'GD&T' from the list of options.  Using this symbol-based editor, you can create any non-standard FCF that you wish.

RE: FCF question

A FCF can only ever have ONE geometric control symbol if adhering to the ASME Y14.5 standard (I haven't worked in ISO or others so can't comment definitively about those.) the proper way to create that callout is to use two frames that are stacked on top of each other. There also can never be a datum reference in a straightness or flatness control. I'm sure John knows that and just put it in there to demonstrate that you can create any non-sensical frame you wish.

I am curious when the FCF function will be changed to prevent the use of datum references and modifiers with controls that do not support them?

@DaSalo,
yes- you are right - I haven't found the information where to find it in the standard - do you have a source?

RE: FCF question

There are many GD&T sites online that you can reference. This is very basic stuff and can be found in any drafting textbook. If you really want to get to the source you can purchase a copy of the ASME Y14.5 standard from ASME. Just go to their website and look at the products available. Your quality dept. should have a copy of EVERY standard that applies to EVERY print that you have. If you don't you can be almost 100% sure that somebody in your organization is misinterpreting something and exposing you to quite a bit of risk.
