Working with Sketched
Features
In this chapter, you learn about parametric part modeling and the process for creating sketched
features on parts.
Parametric Part Modeling
A part model is a collection of features. Parametric modeling gives you the
flexibility to adjust the parameters that control the size and shape of a model,
and automatically see the effect of your modifications.
To create a 3D part model in Autodesk
®
Inventor
™
, you extrude sketch geometry,
sweep or project sketch geometry along a path, or revolve sketch geometry
around an axis. These models are often called solids because they enclose volume,
unlike wireframe models which only define edges. The solid models in Autodesk
Inventor are constructed of features.
You can also create surfaces with many of these operations. Use surfaces to
define shapes or aspects of the part body. For example, a curved surface can be
used as a termination plane for cuts in a housing.
You can edit the characteristics of a feature by returning to its underlying sketch
or changing the values used in feature creation. For example, you can change
the length of an extruded feature by entering a new value for the extent of the
extrusion. You can also use equations to derive one dimension from another.
Using Autodesk Inventor, you can create several kinds of features, including
sketched, placed, work, pattern, and library. Some features require that you
create sketches or paths, while others do not. Some represent visible geometry,
and some, such as work features, help you precisely position geometry on a
part. You can edit a feature at any time.
