In this chapter, I present best practice suggestions and offer a balanced explanation so that you can evaluate the benefits and potential problems associated with in-context modeling. I give you enough facts so that you can decide for yourself how in-context techniques fit into your process.
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.
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.
In its most common form, a sketch in one part in an assembly is related to an edge in another part in the assembly. The relationship is specific to ...
