Thank you, your video was very clear and well thought out and the information well presented. I would ask you to review your description of envelopes. @ 8:07 you stated that the feature could not violate either boundary, this is incorrect. While perfect form at MMC is required the feature can have form error equal to the amount the feature departs form MMC toward LMC. In the example given a 19mm hole could have no form error however a 21mm hole could have as much as 2mm of form error and still meet the drawing requirements. If you were to model a 21mm cylinder that had a straightness of 2mm it would certainly fall outside of the 21mm envelope. In your example the entire hole would have to have a local size (any two opposing points) between 19mm and 21mm and would have to have an AME (actual mating envelope) no smaller than 19mm.
Hi! Thank you for watching and bringing up a good point. You are correct that straightness is an exception to the envelope principle. This tutorial covers and condenses hours of training material into a 30-minute video, so some things had to be left out. If you have any further questions, please let email us at info@capture3d.com. Thank you!
@@CAPTURE3D The reason you could violate the least material boundary is because rule #1 allows it not because of some exception. You need to be careful stating that Straightness is an exception to rule #1. The example given in your video there would be no exception the rule, my original comment stands. Only in very specific cases can straightness (and flatness) allow the feature of size to violate the rule. In order for Straightness/Flatness to be an exception it must be applied to a size dimension.
I agree, the explanation was incorrect, unfortunately. By default, there is a requirement of perfect form at MMC, but no requirement of perfect form at LMC. The ASME Y14.5 standard is very explicit about it. Therefore the explanation and the graphic showing the 2 coaxial cylindrical bounaries is misleading.
Hi! This tutorial introduces how to apply GD&T at an introductory level using a basic example. However, if you need more information about GD&T, there are additional videos on our channel. We also offer training courses on GD&T, and you can see the schedule for those on our website. If you have a specific question, please feel free to reach out to us at info@capture3d.com Thanks for watching!
Hi Tyler, loved your presentation on GD&T and the Zeiss GOM Software. Although I do not see the link to the 'Starting Project file' or the GOM software to follow along. Please advise?
Hi! Stress analysis and testing are performed in the ARAMIS software offered by Trilion in the U.S. Please reach out to Trilion for any ARAMIS questions. www.trilion.com/ Thank you!

I agree with the comment below about the envelope principle. The boundary of perfect form is only at MMC. Please review it.
Will this cover how to create and appropriately apply GDT where and when and not simply how to interpret it.
