Overhaul to support GPS in MBD to most recent ISO

[MikkoHinkkanen]

1. Describe your environment: What is your industry? What is your role in your organization? Describe your stakeholders.
Mechanical Engineering community, excluding ASME Y14.5 users

2. What version of Creo Parametric are you currently running?
Creo Parametric 8
3. Describe the problem you are trying to solve. Please include detailed documentation such as screenshots, images or video.
Currently OOTB Creo Parametric requires quite a lot of tweaking to make it compliant to most recent ISO GPS starndards (Geometrical product specifications).

- ISO 2768-1 & ISO 22081 general tolerances (currently available table is with DIN, and ISO 2768-2 is outdated), use ISO 22081:2021 instead

- ISO 1302 surface roughness (currently outdated symbol)

- etc

General overhaul is suggested to have the system configurable as per used MBD or Drawing standard.

4. What is the use case for your organization?
Implementation of MBD for MBE.
5. What business value would your suggestion represent for your organization?
Standard compliance. Time to market.

Also, hole feature notes should refrence surface rather than edge. From 2D DRW point of view the edge is ok, but for shemantic refrences tje surface is must.

For the DIN part there is DIN 2769 to consider (references/provides tables to be used with ISO 22081)

[Hugo-KTM]

DIN 2769 uses a bounding sphere to select the profile tolerance for ISO 22081, so Creo needs a way to display the bounding sphere diameter for models. (https://www.ptc.com/en/support/article/cs348935 - Is it possible to determine and generate the bounding sphere of a part (similar to bounding box) in Creo Parametric?)

Since some time, ISO 1302 is outdated, and ISO 21920 is the new standard - when will this be supported?

[Hugo-KTM]

Expanding on @SvenR's comment:

I think there are two standards that are going to replace and expand on ISO 1302:

ISO 21920 - Geometrical product specifications (GPS) — Surface texture: Profile

ISO 25178 - Geometrical product specifications (GPS) — Surface texture: Areal
