Selection for 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.

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.
