Before creating solid models, you should have a basic understanding of how NX represents the location and orientation of objects. Since you will be creating models in a three-dimensional environment, model space is defined as the infinite extension of a three-dimensional field represented in the views of your graphics window.
All NX coordinate systems are right-hand, Cartesian coordinate systems,
made up of a set of X, Y, and Z axes, 90° apart from each other.
A three-axis symbol is used to identify a coordinate system. The intersection of the axes is called the origin of the coordinate system. The origin has the coordinate values of X=0, Y=0, and Z=0. The figure below illustrates that, starting at the origin, each axis has a positive direction and a negative direction.
There are several types of coordinate systems that are utilized in NX. This lesson will discuss the following types:
• Absolute Coordinate System (ABS)
• Work Coordinate System (WCS)
