I'd make a note with an arroW pointing to the area: "YOU MUST KEEP TIGHT TOLERANCE ONLY HERE! IGNORE THE REST! BEST OF LUCK: DESIGNER"

I have trouble understanding the F-G, H-I profile definition under the FCF. What I know is that either the all around circle or a "between" or "from-to" arrow can be used. However this "common datum" style designator is confusing to me. And the features being controlled are edges, and a radius...

I have sent you a message, did you receive it? I can't post it here because it's too long.

I have a macro for that which replaces drawing links. I encounter refusal a lot so we always use the macro.

Sorry for the confusion. I meant perpendicular, not parallel. I mean this banana.

The "ball groove" that runs parallel to the cylinder axis. I'm guessing it's either an internal grooving tool or might be a spherical undercut mill. I was wondering which one would lead to cheaper parts and overall better performance.

Hi there! I'm wondering how they are manufacturing the groove inside the square socket of hand tools? I'm familiar with the through hole versions and their dimensions (https://www.engineersedge.com/hardware/square-drive-tools.htm), but I haven't found anything on the groove sizes and methods...

Running products aren't updated automatically, different versions are used parallelly. The dwg carries the revision notes, and it's stated in the title block that a 'number up' is a revision or a version up. Like the picture.

https://www.tec-ease.com/gdt-tips-view.php?q=109 I found this on the subject. Interesting read, it helped me understand with visual examples. (I'm a picture book guy [roll1] )

We keep everything under the parent Mechanical Part. We don't "rename" them when major changes occur. It's essential in PLM. I once started a new prototype development, made the parts etc, did some upgrading and had 3 revisions. Then my colleage joined the project and he put his ideas to use...

We use Siemens TeamCenter and we utilize a dual revision system for part numbers. At the initial release the part number (for this example lets say PLABCDEFGH) gets its first version and revision. The PN will be PLABCDEFGH-01-00 01 is the VERSION 00 is the REVISION When something is changed...

The key in the text is the "location of the envelope". For MME it's INSIDE, for AME it's OUTSIDE. If the feature is at LMC then the LMC IS the UMME. If it's at MMC then the MMC=UAME.

It is imperative to know that in thread connections, the first 3-4 full turns take up 99% of the force applied. Additional turns henceforth are unneccessary. For a usual threaded hole the minimum depth must take into account the length of the thread starting spiral then an additional few turns...

Don't use Teamcenter, that's my advice :) It's possibly the slowest laggiest PLM I've ever encountered.

However: 1.4.2 Cross-Reference of Standards Cross-reference of standards in text with or without a date following the standard designator shall be interpreted as follows: (a) Reference to other ASME Y14 standards in the text without a date following the standard designator indicates that the...
