Use this procedure to add work planes on which to create the geometry of the model. To avoid confusion, work with only one work plane visible, unless you are using offset or reference work planes.
The Create Work Plane dialog box is displayed.
The top work plane is created.
You can add other types of work planes as needed.
You can select any view direction or use the Views toolbar to zoom extents of your work planes.
When you select a work plane in the part browser, the work plane is highlighted in the modeling area.
To avoid confusion, work with only one work plane visible at a time. To make only one work plane visible at a time, in the part browser, right-click a work plane and remove the check from the Visible check box (uncheck it).
When a workplane is marked as unvisible, the workplane icon in the part browser is grayed out, and the work plane itself is not displayed in the modeling area.
