Modeling Paradigms
There are many different types of modeling commands. In mechanical design,
the need for manufacturing precision has led most commands to use some
for of sold or surface BREP (Boundary Representation) modeling technology.
Within these commands there are several approaches and technologies that
are combined to deliver modeling commands with various capabilities and
strengths. For the sake of keeping this page short(ish) we will leave the
discussion of high level modeling out and move onto those technologies that
directly affect Inventor Fusion.
■ Modeling with Features
■ History compared to history-free modeling
■ Explicit or Direct modeling
■ Parametric modeling
■ Dialog vs direct design manipulation
To date most successful modeling commands have fallen into two categories
■ Parametric history based feature modeling
■ Explicit history free modeling
It is not very important to understand everything about the two different
technologies (and the new hybrid applications emerging) but it can be
interesting. There is a lot of miss-information on these topics as different
points of view try to make one modeling technology sound better than the
other. Autodesk does not believe one is better than the other. We believe that
you need both and that you should have the benefits of both as part of your
solution.
Modeling with features
Mechanical designs are not non-descriptive blobs. They are precisely designed
functional objects where features serve a purpose and have defined size. It is
convenient to be able to assign names to these design features. It can be easier
to work with these features because defined behaviors can help make the
creation and editing predictable and efficient.
