By default, every part and assembly has three planes when you create a new part: the front plane, the top plane, and the right plane. These three planes intersect at the origin in the part environment. The planes that are shown in the FeatureManager by default can be renamed and hidden, but they cannot be deleted.
You can see the planes in the graphics area by making them visible in the FeatureManager. To hide or show a plane, do the following:
1. In the FeatureManager, select the plane to be shown in the graphics area.
2. In the context toolbar, select Show to display the plane. When the
plane is set to Show, the icon in the FeatureManager will be shown as
a solid yellow color.
3. To hide the plane, select the plane again, and select Hide from the
context toolbar.
