    Parallel Callout?

    Hi fsincox & Others, There will be .094 pins in the 3rd serrations of the root, but only at the machine stages. Ideally, this is where I would like to establish my GD & T datum Z (horizontal datum) by placing the datum at the bottom or top of the pin surface. Still now sure how this is...

    Parallel Callout?

    Hi Kenat, We are using Datum Targets to establish the 6-point nest. Do you have something else in mind to use these?

    Parallel Callout?

    Hi Frank, Thanks for the feedback. The above practice has been seen or used by some major Fortune 500 & approved by their GD & T gurus, which is probably half the reason I'm confused on this topic area. However, there instances that I've seen more formal GD & T practices, as well...

    Parallel Callout?

    Hi Everyone, This is a follow up question, trying to differentiate the usage of a Datum Feature created within a CAD application, such as ProE, NX or any other CAD application & the ASME Y14.5 Datum. While creating a CAD model, Designers will often create 3 primary CAD datums that often...

    Which Engineering Schools Offer Adequate GD&T Courses?

    Hi, There are some universities that teach GD & T, but typically only the intro. levels. At least the university I went to only taught the intro course.

    Turbine Blade Drawing Template

    Lifttrucks, Yes, CAD Datums used within ProE, NX or whatever other CAD system that are typically used as Primary, Secondary or Tertiary datums when creating (symmetrical) CAD models. I'm guessing the terminology is getting confusing because "Datums" within CAD modeling practices is...

    Turbine Blade Drawing Template

    Hi, I'm not asking for your actual part drawing. I just want to reconfirm some basic datum usage between CAD Datums & GD & T datums & how they are deciphered or referenced between the CAD Model(s) & Drawing(s). I don't need to see title blocks or company names. A screen shot of a...

    Turbine Blade Drawing Template

    Hi, I'm curious to know if anyone has a turbine blade drawing template with proper GD & T datum schemes on it. Preferably, seeking a template for a jet engine turbine blade with a core, but I'm more interested to see how: CAD Datums (from ProE, NX or any CAD application) are used for GD &...

    Parallel Callout?

    Hi Everyone, Thanks again for the great feedback. In dtmbiz's marked up example, Datum Y is moved to the TE root face. During the CAD model creation, which seems to be a typical industry practice, there is a CAD feature called Datum Y. If no longer using this for the drawing side, what...

    Parallel Callout?

    Hi Powerhound & Others, No, I wouldn't do that to the person or the Fortune 500 company he works for. As mentioned, I've seen this practice for as long as I have been working in the turbine industries - aerospace, gas, & other turbine industries. Each has this similar practice & up until...

    Parallel Callout?

    Hi Ewh, That's what I'm trying to figure out to. One of the companies I worked at has high level nationally renowned GD & T "Expert". Additionally, with other major aerospace & gas turbine companies, this datum scheme is a common practice. I assumed this was all in line with ASME...

    Hi Everyone, Please provide your thoughts with the picture I attached above. Thanks

    Parallel Callout?

    Hi Everyone, Attached, is a picture of a commonly used datum scheme used through out the aerospace & gas turbine industries I've worked. From these defined datums, various GD & T would be applied in the drawings, referencing one or more of these primary datums. What are your thoughts of...

    Parallel Callout?

    Hi Dtmbiz, Thanks you very much for the mark up. Some of my GD & T - the Parallel Composite frames did not translate correctly when converting from CAD to a '.pdf'. I also fixed my rotation callouts by moving my 'F-F' & 'AK-AK' callouts to the top view. Here, it's seen that the LE & TE...

    Parallel Callout?

    Hi Everyone, Here's a question. When creating CAD models, we often use a datum plane as center, particularly if the component is symmetrical. This usage or reference to center often gets carried over to the drawings. I agree with the standard, but questioning why all these companies I've...

    Parallel Callout?

    Hi Everyone, I noticed that there's a reference up above to 2009 standards. It doesn't appear which standards the company I work for uses. They are still using ASME Y14.5M-1994 standards. I'm not sure if this makes a difference or if standards have changed with the new version. What...

    Parallel Callout?

    Hi Everyone, Interesting feedback. Unless I'm misinterpreting something here, using a datum at a center was a practice at a major Fortune 500 company that I used to work at. Additionally, this company had a nationally ranked GD & T specialist. I'll have to go back to see "if" I can find...

    Parallel Callout?

    Hi Belanger & Dingy2, Thanks for the feedback. To begin with, the ".010Y" is translation issue from being converted from the CAD application to '.pdf' format. I was trying to define that the section cut (AK-AK) & projected view (F-F) are parallel to Datum Y. As for the callout of F-F...

    Parallel Callout?

    Hi, I have an projected right-side view & need to define the root form of a turbine blade. In the projected view, there is a vertical datum that I'm calling Y. If looking at the top view, I have 2 planner surfaces (LE & TE sides) that are parallel with my datum Y plane. However, the root...

    Section Callouts Within Section Views Prohibited?

    Hi Belanger, Thanks for confirming.
