In-context modeling is an extremely powerful technique for extending parametric design from individual parts to top-level assemblies. With the power comes potential for mistakes. If you are not careful, in-context modeling can lead to unexpected results.

Understanding In-Context Modeling

In-context modeling is also known as top-down modeling. It is a technique used to create relationships between parts in the context of an assembly, where the geometry of one of the parts is controlled by both the other part and the mates that position them relative to one another.

In-context, or top-down, modeling may be contrasted against bottom-up modeling. Bottom-up modeling involves making the parts in their own individual windows and assembling the finished parts into an assembly with mates.
