In principle, I would be delighted to help. However, I can identify two major issues:
- I do not have a great deal of spare (unfunded) time;
- I am acutely aware of awning gaps in my ability to understand much of what is going on here. I do and believe I understand information modelling. I am not sure in a concrete sense of how this relates to the SUO.
If you want a summary of the content then you need to look at the EXPRESS schema:
which references the following schemata:
However, this is only one approach to the modelling of tolerances. I believe that Matthew West would point you at what I suppose is in the EPISTLE Core Model.
