and Parametric Modeling
3
From a dictionary
A Parameter is any set of physical properties
whose values determine the characteristic of
something.
4
When using Inventor?

The something is sketched geometry
and
The physical properties are the shape and size
of the sketched geometry.
So, Parametric Modeling is determining the shape
and size of the geometry with parametric
constraints.

Inventor Steps contd
Step 2 Constrain geometry A. Apply geometric
constraints
8
Geometric constraints applied first
Geometric Constraint Tools

Inventor Steps contd
Step 2 Profile geometry A. Apply geometric
constraints B. Apply dimension constraints
10
Dimension constraints applied second
Dimension Constraint Tool
11
The geometry that has been constrained is a
profile of an object.
