This book de-mystifies ModelCHECK to improve 3D CAD model quality in PTC Creo. Supports Model-Based Definition (MBD) with implementation steps and checklists for organizations to develop 3D CAD models with geometric and parametric stability, accurate metadata, and re-usable Product and Manufacturing Information (PMI). Provides step-by-step instructions to automate checks for modeling rules and best practices from relevant MBD standards, model parameters required for Technical Data Package (TDP) submissions, incomplete Product and Manufacturing Information, and standard features such as datum planes, axes, and coordinate systems. Takes users "under the hood" to understand and configure ModelCHECK files and interpret ModelCHECK reports. This handbook, the second in the Re-Use Your CAD series, is geared toward CAD Designers & Engineers, QA/QC & Product Inspection, Database Administrators, Information Technology (IT), and their Managers.Minor updates made in May 2017 - Revision 2.Look for the Creo 5.0 handbook shortly after the Creo 5.0 release!
