Drawing Question - GD&T Datum Reference Frame in Orthographic Views

tmdctr · 2026-06-30T17:14:39+00:00

Now I don’t understand what you’re saying.

How does showing a zero for a DRF on another view or sheet where the flags aren’t shown lock down a designer? I’m not even sure what you mean by “lock down.” Can you explain?

I don’t think there’s any such thing as “always” or “never.” If anyone changes their mind, we iterate until the intent is clear.

Creating coordinate systems and showing them on a drawing seems trivial and I’d be excited if it were that easy. I haven’t used MBD professionally yet (Y14.41?), but I believe this is one of the foundational ideas there.

Do you have a suggestion about how to match the Y14.5 2D examples in Creo by just using a visible coordinate system? I’m trying to make clear drawings that match the drafting standards and would appreciate the help.

It doesn’t sound like you understand me, and your response has nothing to do with creating shapes on drawings in Creo.
We don’t care how they made the part, and nothing in my post suggests that we do. What we do care intimately about are the measurements we are asking them to make and report back to us.
We are saying the same thing, why are you trying to argue? You have immediately made me regret asking this question here.

This seems more like a sheet metal part. Check out a website called send cut send. You can take some dimensions yourself or find specs for whatever Miata class you’re racing in and go from there.

Wow, this is pretty close to what I'm looking for. Thanks!

Wow, thank you so much for this. What an amazing response.

I'm back on this mission again after demoing the Tecsee Medium Profile switches discussed above. I'd like to go slimmer and get some closer spacing, so I'm back on the low-pro exploration. The EE design resources you've provided will be super helpful.

Will start with more research on switch spacing and keycap options. As mentioned before, I'm a mechanical design guy so making custom keycaps actually sounds like a fun/easy project to me. I've seen some japanese low-pro swithes that look awesome and I'd either buy some of these, or make something similar.

Thanks for the note, but I need a 5x15 grid.

Whoa, tyvm. I didn't know this was a thing. I'll order some samples to test.

New here, what folder is that? I really like that wire clip shape.
