Datum CSYS examples

Defining critical locations in a product assembly

For an aerospace vehicle, you can create a datum CSYS at the absolute origin to define the vehicle coordinate system. You can create another datum CSYS to define the wing coordinate system. You can then use the wing coordinate system as reference to design and position the parts in the wing assembly structure.

Creating features in a detailed part

For a detailed part, you can use a datum CSYS to help define the location and orientation of features. This is useful when there are no convenient edges and faces or when you need to control the location of features with multiple translation and angle parameters.
