Datum CSYS

Use Datum CSYS to quickly create a coordinate system consisting of a set of reference objects. You can use the reference objects to associatively define the position and orientation of other features.

An existing datum coordinate system at the absolute coordinate system origin is included in many of the default part templates.

A datum coordinate system consists of the following reference objects:

• A coordinate system
• An origin point
• Three datum planes
• Three datum axes

You can create a datum coordinate system:

• At a fixed location relative to the work or absolute coordinate systems.
• Associated to existing geometry.
• Offset from an existing datum coordinate system.

Reference objects in a datum coordinate system can be used to define:

• Placement faces, constraints, and position of sketches and features.
• Vector directions for features.
• Critical product locations in model space and control them with translation and rotation parameters.
• Constraints to position parts in an assembly.
