Planar objects with solid fills are drawn in stacking order. In a 3D wireframe view, objects may overlap, obscuring objects lower in the stacking order. The wireframe options control whether fills should be visible for planar objects in 3D views, and if they are visible, sets the fill opacity of filled planar objects.
To set wireframe options:
1. Select View > Rendering > Wireframe Options.
The Wireframe Options dialog box opens.
Click to show/hide the parameters.
2. Click OK to set the wireframe options.
