Creo Parametric - Geometric Tolerances (GD&T) - Model Based Definition (MBD)

[@tjvanderloop1686]

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 "KZbin" 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.

Thank you for sharing such informative videos! I am new to CREO; but your channel is making life easy!

[@CADPLMGuy]

I’m glad to hear that!

[@tjvanderloop1686]

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. T J (Tom) Vanderloop, Author, Mechanical Designer, & Consultant: ATEA, AWS & SME-Life Member/Leader

Thanks, TJ!

This video is all I needed to get up and running on MBD. Thanks!

[@CADPLMGuy]

Glad to hear that!

[@CADPLMGuy]

Dave’s not here, man

[@DavidJones-mq6vc]

@@CADPLMGuy haha! I didn’t think Dave was old enough to know that one!

Very informative and helpful videos. I appreciate and thank you for your work. please keep uploading more videos.

[@esrAsnataS]

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.

[@CADPLMGuy]

Do you have Show Annotations turned on in the In Graphics Toolbar?

[@csullymon29]

I think a diameter symbol was intended to be added with the tol value in the positional tolerance callouts

[@CADPLMGuy]

Oops! Very likely.

[@SeanMcDonnell33]

Very helpful. Thank you!

[@jamiechance]

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!

[@CADPLMGuy]

I don’t recall auto basic dimension. Can you remind me what version that was and how it was done?

[@jamiechance]

@@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.

[@CADPLMGuy]

@@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.

[@goodtime01]

Can anyone tell me why flatness value i am getting as .005 and not 0.005 Thankyou.

[@CADPLMGuy]

It’s based on your drawing standard. I forget which is which, but I think ISO has the leading zero and ANSI does not.

[@franciscojaviergonzalez-ca3706]

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

[@CADPLMGuy]

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.

[@franciscojaviergonzalez-ca3706]

@@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

[@CADPLMGuy]

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.

[@franciscojaviergonzalez-ca3706]

@@CADPLMGuy Great, thanks a ton. Your videos have been saving me in grad school!

[@tuyentran3602]

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

[@nabeelk]

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?

[@CADPLMGuy]

Set the tol_display config option to yes.

[@nabeelk]

​@@CADPLMGuy Thanks a lot Dave, you are awesome.

[@BenitMano]

With MBD, can we dimensions in isometric view??

[@CADPLMGuy]

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.

[@talentadoka]

What Creo version is this?

[@CADPLMGuy]

Based on the date it was published, probably Creo Parametric 6.0.
