GD & T Questions
GD & T Questions
(OP)
Our company is training for GD & T, and I have a couple of questions for all you gurus out there.
1)What is the correct interpretation of an area indicated by section lines inside the phantom line?
2)Which symbol should be used to express coplanarity of two or more features?
3) Can anybody refer us to a pocket-sized reference guide for use on the production floor?
Thanks in advance for any guidance offered.

2) If all surfaces are co-planar, you could label all of them as the same datum plane (or you could use parallelism)
3) Lowell Foster wrote a pocket size reference booklet, but I'm not sure where you could get it from.
You could post this question in the GD&T forum and get more of a resonse.

On the other hand, your suggestion:
"you could label all of them as the same datum plane"
would make sense.
Karman303: I recently took a course in GD&T where they provided us with a pocket guide. Monday at work I will get the info to obtain copies. Probably you will already have the info from the GD&T forum by then but that is OK too.
Your first question has my head spinning. I trust you will make it more clear when you post it on the GD&T forum.

Just kidding
I'm not clear on the question. I would suggest buying ASME-Y14.5.
