ASME Y14.41-2003 & Adobe PDF....

Hello Forum,

I don't enjoy the circular process of turning my 2D concept sketches into 3D CAD geometry, to only revert it back to a 2D engineering drawings...seems wasteful. I don't see the point in entering data twice (i.e. once in during 3D CAD and again in the 2D drawing). I don't like having to update changes in two places. Hence, I'm very excited about moving to the new ASME Y14.41-2003 standard.

What does the forum think about using Adobe 3D as a standard exchange format for ASME Y14.41-2003 engineering control data?

The reader is free (i.e. Vendors don't have to pay for the ability to view 3D design information). Vendors can measure , section, and study the part to their hearts desire. And lastly, they can use the 3D PDF data to export a suitable IGES or STEP file for CAM import (we only need to send the vendor one small file) In addition, it lends to easy revision management using current PDM solutions...and the list goes on. Anyone agree?

Check out the feature demo:

It seems like the biggest hurdle is affordable CMM inspection equipment. Here's to 2D drawingless world!

P.S. And no, I don't work for Adobe or its subsidiaries.

I don't know. Maybe I'm old fashioned (pretty hard to be, as I'm under 30). I learned from a guy who's done drafting for 30+ years, and to me there's nothing more satisfying than sending that beautiful 2D masterpiece through the checking system, and finding everything to be perfect.

To me, a perfectly drafted engineering drawing is the Mona Lisa.

True... But that's what makes it so beautiful.

"To me, a perfectly drafted engineering drawing is the Mona Lisa."

This statement warms an old draftsman's heart.

The rarity is to find a master draftsman, that also has mastered modelling and drafting in a state-of-the-art parametric CAD system. Put those two together, and you get great drawings.

Ron, happens about as often as when you put together a hog and a pair of wings and it takes off;-), or the blue phase of the moon.

vc66 - I've come from your world and have the drawings to back that UP. I was schooled by an old school draftsmans/designer. It was tough going but I came out of it with what I consider high valued skills.

Recently I spent some years working in the automotive industry where it was very rare that the drawing was up to date with the math data(CAD). I see some BIG time value in 3D dimensioning in this very fast paced environment.

Generally speaking, with all modern CAD tools the drawing simply reflects the model so it is always up to date. Now if you are looking at some static snapshot like a PDF file it won't update. 3D PDF will not help that problem.

I looked for the functionality on their website. Where's this function "hidden"? Does the free viewer have this function? If so, I will likely start the ball rolling to switch from using flat PDF's to 3D PDF's at my company (instead of eDrawings, which is another possibility I'm considering).

Everyone,

Thank you for all the feedback, both positive and negative. FYI: On a hot project, given the track record of that vendor, I sent an IGES file over, without a drawing, so he could start CNC programming early. Well I got a phone call, asking for...a drawing. This time, he claimed he couldn't start without a drawing.

So we're all smart and imaginative. Here is the future, as provided by a simple example from the past. Automotive and Aerospace have lead the way for engineering technology. Computerized 2D drafting, FEA, 3D CAD, CFD, PDM, and PLM are just a few of the technologies these industries have pioneered for larger engineering community. As several post on Eng-Tips have covered, Aero and Auto are nearly paperless now. Hence, it only a matter of time.

Currently we have a chicken and egg scenario regarding ASME Y14.41-2003. Design firms aren't using it because the vendors aren't using it, and vendors aren't using it because design firms aren't. Well, this scenario is easily broken by the the vendors customer (design firms). I'll be sending out MBD (PMI) in Adobe 3D in accordance with ASME Y14.5M and Y14.41. I'll work with my vendors to implement the system and train them is using the information provided, as Toyota would. This will help our small vendors lead the way into the future, provide a competitive edge, and possible keep manufacturing on these shores a bit longer.

The future will be paperless, MBD (PMI) will define the contract with vendors (its being done in Aero and Auto as I type), and all the supporting equipment; CAD workstation, CNC Workstation/Machines, CMM Workstation/Machine will use this information seamlessly. The trees and will thank us.

Thanks again for the feedback and cheers to a paperless future.

dmech, good luck.

From the little I've dealt with it I'm wondering if you realize what you've got yourself into.

In my opinion, 14.41 isn't being used because it is not ready for prime-time. It is over specific on some instructions, and leave other areas without any comment at all. It seems like it was written in a vacuum without much input from the 3D CAD industry, or maybe too much input from one particular portion of 3D CAD industry.

I did write one letter to the 14.41 committee about some of the issues with it. I never got a response.
