Computer-Aided Industrial Design
Computer-aided industrial design (CAID) is a subcategory of CAD that includes software,
which directly support in product development. Designers have the freedom of creativity
yet generally follow a simple design methodology within CAID programs: Using a stylus to create sketches
Using the sketch to generate curves
Using curves to generate surfaces
By following this design methodology, the end result created is a 3D model, which
envisions the main design intent the designer had in mind. The model then can be
saved in STL format (a file format for stereolithography and other solid freeform
fabrication technologies) in order to send it to a rapid prototyping machine so
that the real-life model can be created. CAID allows designers to focus on the
technical portion of the design methodology. Once a requisites and parameters of
the product have been defined by using CAID software, the designer simply has to
import the result into a CAD program, which is usually a Solid Modeler, for modifications
prior to production and the generation of blueprints and the manufacturing processes. CAID is a more conceptual program than CAD, which is more of a technical program.
The designers have the freedom to express themselves when using a CAID program,
yet when using CAD software there is always the manufacturing factor the designer
must except.
