Creo Parametric - Geometric Tolerances (GD&T) - Model Based Definition (MBD)
HTML-код
- Опубликовано: 4 июн 2019
- This Creo Parametric tutorial video shows you how to implement Geometric Tolerances as 3D Annotations in a part model in conjunction with Model Based Definition (MBD). In addition, it shows how to set up Annotation Planes, show model dimensions, and define Datum Feature Symbols.

Very informative and helpful videos. I appreciate and thank you for your work. please keep uploading more videos.
Both Al & Scott Neumann (Geo-Tol.,) are Excellent Resources for 3-D Parametric Modeling. Size, location controls, (Profile can be location orientation & form) orientation controls, and form controls detail-the SLOF hierarchy. Yon can show more "Geo-Tol" examples as these guide the novice to the flexible language of GD&T. Keep doing quality 3-D modeling of "RUclips" geometric tolerancing CAD/CNC video parts. A Big THANKS!

Agreed! I haven't taken classes from Al, but Scott completely demystifies GD&T. Anyone interested in learning should definitely reach out to them.
Very helpful. Thank you!
Thanks for the 3-D Parametric modeling using GD&T with Creo/CAD-Software. This is a good video for mechanical design technicians and engineering technology professionals.

Thanks, TJ!
Thank you for sharing such informative videos! I am new to CREO; but your channel is making life easy!
I’m glad to hear that!
This video is all I needed to get up and running on MBD. Thanks!
Glad to hear that!
@@CADPLMGuy thanks! Is this Dave? Haha
Dave’s not here, man
@@CADPLMGuy haha! I didn’t think Dave was old enough to know that one!
@@DavidJones-mq6vc I'm in my 50s. As kids, we were watching Cheech & Chong on HBO way younger than we should have been.
Why do we get datum reference frame and why it ask's for coordinate system can we delete DRF?
Hi, could you show how keep the geometric tolerance at 3 decimal like .010, I'm currently using Creo 4.0 and it keeps removing the last zero to .01. Thanks
Hi Dave, great tutorial as usual. However my annotations disappear as soon as I click "OK" about 9:12 in the video.
I have the DRV_DIM list showing but when I click on them the annotation does not show. I am in the "Default All" tab
as I have not attempted MBD tabs yet.
Do you have Show Annotations turned on in the In Graphics Toolbar?
I think a diameter symbol was intended to be added with the tol value in the positional tolerance callouts
Oops! Very likely.
Hi Dave, when I try to make a dimension as basic dimension my TOLERANCE drop-down menu was grayed. The same happened to me when I try to put +- tolerance.
Am I missing any step?
Set the tol_display config option to yes.
@@CADPLMGuy Thanks a lot Dave, you are awesome.
Can anyone tell me why flatness value i am getting as .005 and not 0.005
Thankyou.
It’s based on your drawing standard. I forget which is which, but I think ISO has the leading zero and ANSI does not.
With MBD, can we dimensions in isometric view??
With MBD you can create dimensions in any orientation; in 3D there really isn't an isometric view. It's just a matter of selecting the appropriate Annotation Plane before creating a dimension.
did you need to state a "2 X" on the smaller hole annotation or is the other hole going to be annotated on another plane? sorry if i missed it in the video
I made that video 2 years ago. I don’t remember. I could have missed the 2X as I was probably concentrating on the Geometric Tolerances given the title of the video and not the dimensions.
@@CADPLMGuy Sorry I didn't mean to correct you or anything, just curious if the wholes were different sizes and you were going to apply annotations on another plane or something. Thank you
I don't remember the diameters. From what I remember of the video, I didn't fully annotate the model. The intent was probably to show people how to create a few datums and feature control frames.
@@CADPLMGuy Great, thanks a ton. Your videos have been saving me in grad school!
Previous versions of Creo did an auto basic dimensions. In these newer versions is that not the case anymore? I noticed you had to make your own dimensions basic!
I don’t recall auto basic dimension. Can you remind me what version that was and how it was done?
@@CADPLMGuy all versions prior to ribbonizing gdt and dimensions? Def Creo 2 and prior. I'd add a gdt and it would ask if I wanted to make all dims associated basic and I'd select yes.
@@jamiechance I don't recall that at all. Not doubting you, I just don't remember that. I recommend opening a ticket with PTC Tech Support.
What Creo version is this?
Based on the date it was published, probably Creo Parametric 6.0.
