Assembly Design
Very few finished designs are a single part. Usually a finished design consists of several to
millions of individual parts to define them. This is where CATIA V5 assembly design is
utilized. Assembly design allows parts and small assemblies of parts to be inserted to make
larger, more complete products. In CATIA V5 Part Design and Sketcher, you learned how
to generate parts. The primary objective of this class is to utilize those parts to create a
complex assembly of those parts that can be later used in stress analysis, kinematics, fitting
simulations, and other areas.
It is important to understand some of the terminology that CATIA uses when working with
assemblies. There are basically three types of documents that are used in assembly design.
They are the overall assembly, sub-assemblies and individual models. CATIA uses the
word products to refer to assemblies and parts to refer to individual models. You can use
parts to create products and then in turn use those products to produce other products. The
diagram shown below represents the concept of the overall structure.
