Work planes define the orientation in which you are working. They provide access to views, such as Front, Side, Top, etc., that let you create content.
Use this procedure to add work planes to create the geometry, paths, and constraints of a model. To avoid confusion, work with only one work plane visible, unless you are using offset or reference work planes. The following instructions refer to the part browser. The part browser is located under the ribbon to the left of the drawing area.
The Create Work Plane dialog box appears.
The ZX plane, YZ plane, and XY plane are created.
When you select a work plane in the part browser, the work plane is highlighted in the modeling area.
Selecting the ZX Plane
The ZX Plane and XY Plane icons are unavailable (shaded). The YZ plane is the only visible work plane in the modeling area.
