Basics of Skeleton Models

Skeleton Model (n). A feature of top-down design in which a model sets and defines design intent and product structure at the beginning of the design process. In this article: What is a skeleton model? Skeleton feature types: datums & surfaces Why are skeleton models

Direct References vs. Copy Geometry

Copy Geometry (n). Geometry that is a copied representation from outside of the model. In this article: Creo Definitions Direct References vs. Copy Geometry Creo Definitions Before diving into the nuances of copy geometry, we must first understand the different types of geometry that can

Working with External References

External References (n). A link between features, where one or more features depend on a component outside of its current assembly context.  In this article: How to think about external references How external references often impair model performance How to Think About External References Let’s

The Details of External References

As a CAD assembly increases in size, load time and model performance become increasingly important factors. In one of our earlier posts (see here), we covered ways to manage assemblies and how their components interact with the top-level model in Creo. This series will cover

Assembly Interface Management

The bigger a system is, the more complex it is; this is no different for large CAD assemblies. Each component of the assembly is constrained to other components, sub-assemblies, and the top assembly – maintaining these references is referred to as interface management. In a normal
