Vertical Feature Control Frame
Vertical Feature Control Frame
(OP)
To the best of my knowledge, ASME Y14.5M-1994 does not explicitly say the GDT feature control frame must be horizontal, but I'm assuming it does. A coworker asked me if I thought a vertical box is allowed, and I'm not 100% certain the control frame has to be horizontal. Any thoughts??

So while it doesn't explicitly state FCF I would say that FCF are a form of dimensioning so should be read from the bottom.

RE: Vertical Feature Control Frame
Just reading that doesn't really make sense to me. After all, vertical text (baseline dim.s) can be read from the bottom up. They clear that up with the examples shown. It would be easier to understand if they specified left-to-right, but maybe I'm missing something here.

Make sense?

I guess it really boils down to what you are used to seeing.

That said sometimes having to put everything horizontal can be a pain.

RE: Vertical Feature Control Frame
IMHO, the horizontal rule is more important nowadays than even back in the pre-CAD era. Reason is that all documents are natually viewed flat to the screen where the top of the document is the top of the screen. I disagree with using vertical text on documents these days because it requires the average person to tilt their head or find some way to rotate the document (which is different in each program, and even from version to version of a program...not to mention the fact that many programs think the rotational move is an edit that is meant to be saved).

To me, the most important concession to reading drawings on computer screens is to use compact sheet sizes. Nicely spaced dimensions with vertical text on vertical dimensions can frequently allow the use of 1 size smaller drawing sheet compared to awkward irregularly spaced dimensions with horizontal text on vertical dimensions.

Still this is bellyaching and off topic, sorry.

RE: Vertical Feature Control Frame
The answer to jdg268's original question is that ASME doesn't allow for vertical GeoTols. My opinion is that I agree with this.
