Thanks @hawcad.

The mating face is actually the 2 faces that make up the 15 long section.

The groove in that face is for the location of a screw.

I'm not worried now as the drawings were issued last week and everyone is happy.

As you say, I should really show 'common zone' - but I doubt some of the fabricators would understand it anyway Smiley Frustrated.

I heard a story a few years ago about a fabricator that didn't really know what GT symbols were - so "we just do the best we can, because it must be important".

I've also worked for companies that actually discourage their use as manufacturers immediately increase their prices when they see them on a drawing !

Hi @beachcomber

 

 

Yes this really is a big issue, but IMHO GT symbols are and will become more and more important.

 

There aer many situations of - as You mentioned - that people doesn't know the facts and therefore see something strange, something expensive with those symbols, what they infact are not.

 

Those dimesnions and tolerance standards IMHO makes the drawing issue a lot easier and a big easier and clearlier to understand and to reproduce.

 

So I only can work to make more people common to use that informations.

regards
Wolfgang

That kind of nonsense has been going on since the founding of GD&T.
