## Viewing Clearance Planes

You can easily display the active clearance plane as a translucent image in the Graphics Display window by selecting the Toggle Clearance Plane Items icon from the Graphic Items toolbar. By default, the active clearance planes are displayed as white translucent planes; while all non-active clearance planes are displayed as white polylines.

Sample Clearance Plane Displayed as a Translucent Image

PC-DMIS will display up to one clearance plane along each axis, for a maximum of three clearance planes at a time (one along Z, one along Y, and one along X). If you have more than one clearance plane defined along the same axis and it isn't the currently displayed clearance plane, it will display the most recently displayed clearance plane used on that axis.

Sample Active and Non-Active Clearance Planes

You can further control the display of both the active and non-active clearance planes by modifying these registry entries located under the OpenGLSettingsClearancePlanes section inside the PC-DMIS Settings Editor:

- ActiveSymbol - Displays the active clearance plane as either a polyline or transparent plane (0=Polyline; 1=Transparent Plane; Default=1).

- ActiveColor - Determines the color of the active clearance plane.

- ActiveLineWidth - Determines the line width of the active clearance plane when drawn as a polyline.

- ActivePercentTransparency - Determines the amount of transparency for the active clearance plane.

- Symbol - Displays the non-active clearance lanes as either polylines or transparent planes (0=Polyline ; 1=Transparent Plane; Default=1).

- Color - Determines the color of the non-active clearance planes.

- LineWidth - Determines the line width of the non-active clearance planes when drawn as a polyline.

- PercentTransparency - Determines the amount of transparency for the non-active clearance planes.

These topic are described in further detail in the your PC-DMIS Settings Editor documentation. See "Modifying Registry Entries" for information on how to use the Settings Editor.
