Hi, I see Rhino V9 wip now has GD&T dimensioning, I was wondering how many users use it in there workflow or even outside of rhino or if this is something left more to engineers? I found this vid interesting and I like how the op uses rapid prototyping to quickly check parts and tolerances. Toler…

We use it in our workflow for aerospace clients… however it’s still really really difficult to have engineers sit down and understand how tolerances stack up. I personally feel that GD&T is amazing but the notation is weak… what would really really be cool if you could develop the tolerance stack in…

I was a big proponent of GD&T functionality being added to Rhino. It isn’t necessarily something I use a lot, but when it’s required, it’s required. I’m grateful for the fact that it is part of the Rhino 9 WIP Separate but related, I am also of the opinion that education around GD&T worldwide is we…

It is a vital part of what we do here. I’m glad to see it in V9. I wrote my own a few years back, but maybe it will be time to retire it. [image]

Hi All, I’m getting into the details trying to learn more about it for a few projects and appreciate the candid responses and for sharing your experiences it really helps seeing what others have to struggle with and where they feel the strengths are. [image] arash: what would really really be …

[image] 3dsynergy: Do you find that the new GDT tools in Rhino meet your requirements or is your version still better suited for your needs? If so what is Rhino’s version lacking? From what I’ve seen so far the new GD&T tools in V9 look good, but this only covers the feature control frame. Un…

Hi Dan, That’s good to know and doesn’t that make Rhino’s V9 version unusable for the most part? This should be quoted on McNeels GD&T posting so they know what is missing. RM

Hi Dan - [image] DanBayn: I don’t see a way to add “Datum Features” […] You can create the datum identifier: [image] Leaders are not currently part of the GD&T tool. That request is on the list as RH-89151 GD&T: Include a Leader Option [image] DanBayn: […] suppress redundant zeros f…

Hello, I started playing with this feature today. It’s good to have it, but the current workaround with two leader notes makes declaring bases way too finicky. Having a leader as a part of the GD&T note is a must for it to be useful. Picture below shows a list (not fully exhaustive) of ways to decl…

Hi Vojtech - [image] Vojtech_Liska: Having a leader as a part of the GD&T note is a must for it to be useful. As noted before, that issue is on our list as RH-89151 GD&T: Include a Leader Option [image] Vojtech_Liska: All regular CAD SWs I’ve ever worked with have the base symbol as a s…
