How do you implement automated design validation using NX Check-Mate and custom checks?

NX Check-Mate implementation involves: selecting standard check sets (manufacturing, assembly, drafting compliance), customizing check parameters for company standards, creating custom checks using Check-Mate authoring tools or journaling/NXOpen API, integrating checks into design workflow through Teamcenter lifecycle actions, establishing pass/fail criteria and reporting formats. Custom checks can validate naming conventions, hole standard compliance, minimum fillet radii, draft angles, and parametric relationships. Results can be exported to HTML/XML reports for design review documentation.
