Referencing Coordinate Systems

You can reference all parts of coordinate systems, such as planes, axes, and origin, in downstream features. For example, you can sketch on the XY plane of a coordinate system or use the Z axis of a coordinate system as the axis for a revolve feature.

Plane Axis Origin
In a part or assembly, click Insert > Reference Geometry > Coordinate System and create the coordinate system. Hover over a plane, axis, or the origin to highlight each entity. This functionality is useful for actions such as sketching, mating, and more.
To see this functionality, show coordinate systems. Click View > Hide/Show > Coordinate Systems.
To select an entire coordinate system instead of the origin or individual planes or axes, in the graphics area, Alt + select the coordinate system.
