This chapter provides the information you need to make informed decisions about whether or how to use this powerful tool. In-context modeling is a topic worthy of some investigation before you combine production data with external references. Almost anything you can do with in-context modeling can also be done another way, but in-context is the traditional way of using the geometry of one part to drive another.
In-context modeling extends parametric design from individual parts to top-level assemblies. With this power comes the potential for unexpected results. If you are not careful, in-context modeling can lead to difficulties with file management and loss of control over changes.
Understanding In-Context Modeling
In-context modeling is also known as top-down or in-place modeling. This technique is used to create relationships between parts in the context of an assembly in which 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.
In its most common form, a sketch in one part in an assembly is related to an edge ...
