I think it was a quick test to determine how confident you were in your knowledge of GD&T. If you immediately came back with "You can't measure the true position of a tube using only a micrometer" you may have been considered for the position.

Our engineering drawings state "THREADS IAW FED STD H28A" in the tolerance block.
My question is... WHY? I've asked around and since it out dates most of the people here, nobody seems to know why.
If we removed it, it would envoke ASME Y 14.100 which references 14.6 which references ASME B1.X...
3DDave,
Does your organization also state that by approving the ECO you are also approving the changes to the drawing(s)? Do the drafters add names/dates to the drawing title block after the eco is approved?
I wish there were some guidance in AS9100 or ISO on this topic so we knew the decision...
Our Engineering department is having a debate regarding when to add Revision Approvals (Names/Dates) to a drawing. Keep in mind that we document both Initial Releases and Revisions on an ECO (Engineering Change Order) via Oracle ERP. Also, depending upon the contract, the customer may need to...
Looking for feedback from people who are EXPERIENCED in defining Controlled Unclassified Information (CUI).

Scott (@swertel),
If I wanted to PM you (or any other participant) to create a more direct dialog, how could that be done? I don't see an option for that on this forum, without requesting their email, which then goes public.[sad]
I appreciate everything you provided and will look into taking a...
Could someone please explain where this thread is leading. I fee like I'm in the twilight zone!
What the heck is a C compiler, D&T, pre-processor, etc.? And what does it have to do with ASME Y14.5?
This is a discussion about DRAFTING not software code! Why are you mixing the two?

We are trying to standardize on what verbiage we use to indicate that a drawing has not been released for production. We have 8 designers whom all have there favorite.
Historically, one of the following:
PROTOTYPE
Pros - Clearly states the intended use of the part and usually, the state/phase...
What if we started incorporating an overall profile tolerance? That seems to be the global solution for the Model Based Definition effort. Or would that not apply to 2D Drawings where 3D model is no supplied?

So my note would say, "PERFECT COAXIALITY AT MMC REQUIRED FOR RELATED FEATURES"?
This might work!
Thanks KENAT!

Many of our components consist of complex multi-step bores and or threads.
In an effort to reduce overly redundant Feature Control Frames we would like to have add a general callout to our tolerance block.
I've seen "ALL COAXIAL FEATURES TO BE RUNOUT WITHIN .005" before, but I thought runout...
Scott (@swertel),
Yes, Drawings and ECO's have separate unique ID's. For example, Drawing Number 256-928734 will state "RLSD IAW ECO OPB-1615" in the Revision Block.
In our process (see attached) we make changes to the drawing based on the approved ECR. The Engineer will review the Drawings...
@JNieman,
At our company:
We state on our drawings that we are compliant to ASME Y14.100.
We state as a company that we are compliant to ISO 9001 an SAE-AS9100.
My JOB is to ensure that our Change Control process is in compliance with all those standards.

@swertel,
You would be a lifesaver if you could PROVE that the Drawing and ECO are two separate documents requiring their own sign off?
This is what I am trying to prove. I've searched ASME, SAE, ISO, Etc.
The fact that you are a CMII-P certified practitioner, and have the same opinion as I...
@swertel,
Not sure what PDM system you're using, but we use SolidWorks PDM Pro, which can add names and dates to the drawing in real time during approval without any users having write access to the files.
This is done by the PDM System driving Custom File Property values which are linked to...
KENAT,
You're close. An "Approval Indicator" is something like a Quality Stamp, which is issued to and under full control of that person, but could also be the approvers initials, as long as your system can prove that person was the one who put them there. A good PDM System can support this...
swertel,
Thank you. I agree that it is related to a Configuration Management issue. But everything I research on CM always relates to software development. I have not found anything that defines or demonstrates CM as it relates to Engineering Drawings.
I will have to look up the Engineering...
drawoh,
Our ECO process is:
[ol 1]
Our Highly Talented Aerospace Designers (or as you put them "CAD monkey's") are assigned an ECR, which they use to create an ECO in our ERP System (Oracle) and makes changes to Models and Drawings in our PDM System (SolidWorks PDM Pro).
A PDF is made of the...
JNieman,
You actually got me pegged pretty well. I humbly admit to being a high strung perfectionist. [sad]
And you are also correct that I shouldn't have to fix a problem that may not exist. Everyone else IS perfectly happy and we have never been sited on an audit, but we also have no record of...
Dave,
Even though companies may do things differently, doesn't make it right. The reason we have National (and International) Standards, is to establish a baseline, defining a proven process by which everyone should comply to. The more we get off track, the harder it is to return.
Even when I...
