Base reference planes cannot be deleted or created, but they can be either global or local reference planes. Moreover, options available for creating global reference planes or local reference planes are same. We will discuss the available options for creating global as well as local reference planes with respect to the below attached snap (Click on the snap to enlarge):

To create global reference planes you have to click the respective reference plane icons from the feature tool bar, and for creating local reference planes you have to click the respective reference plane icon from the SmartStep ribbon. The rest of the procedure is the same for global as well as local reference plane creation.
1. Coincident Plane: You can create a plane coinciding with another plane or face by clicking the “Coincident plane” icon either from the feature tool bar or from the SmartStep ribbon. Select on the plane or face where you want the new reference plane to coincide.
2. Parallel Plane: You can create a reference plane parallel to an existing plane or surface by clicking the “Parallel plane” icon. You have to select the plane or face of which you want your new reference plane to be parallel. Also, you have to specify the dimension between the two planes.
3. Angled Plane: You can create a plane inclined with some face or plane by this option. You have to select the face and edge to define the angle.
4. Coincident Plane by Axis: This is similar to the “Coincident plane” but you can orient the resultant plane here.
5. Plane Normal to a Curve: You need to have a curve first. Select the curve as input here, and you will see a reference plane created. You can drag the reference plane by mouse to place it at suitable position.
6. Plane by Three Points: Select any three points and you will get a plane joining those points here.
