This document discusses three types of coordinate systems used in mechanical engineering: the Model Coordinate System (MCS) which defines the reference space for a model's geometric data; the World Coordinate System (WCS) which serves as a global reference; and the Screen Coordinate System (SCS) used to represent how models appear on a computer screen. The MCS can be defined arbitrarily by the user, while the document provides an overview of the different coordinate systems without detailed explanations of the WCS and SCS.

• Model Coordinate System (MCS)
• World Coordinate System (WCS)
• Screen Coordinate System (SCS)
4. Model Coordinate System
The MCS is defined as the reference space of the
model with respect to which all the model geometrical
data is stored. The origin of MCS can be arbitrary
chosen by the user.
