Creating Unassociative Arcs
In this tutorial, we'll look at creating unassociative arc objects. So, with all the whiz-bang technology in NX, why look at unassociative arcs? The answer is three-fold:
- the creation methods are simple and straightforward
- the methods will introduce other NX data structures
- the geometry itself is perfectly valid and useful for modeling operations, title block geometry, logo art, etc
In short, the goal of this tutorial is to show you how to create useful geometry and introduce you to a few concepts that you will run into again when working with other NX object types.
The API offers three basic ways to create unassociative arcs:
- through three specified points
- with a given center point, orientation matrix, radius, start angle, and end angle
- with a given center point, an X vector, a Y vector (together, the vectors will define the arc's orientation matrix), radius, start angle, and end angle
We'll take a look at each in turn.
