6、ng planes can be created, displayed, modified, or deleted using the Arbitrary Clipping formClipping planes can be created using a direction/location, vector, or planeClipping planes can be specified to move with the modelMultiple clipping planes may be active concurrently (maximum of 6 at one time)

7、DISPLAY DISPLAYDisplay tools are used to organize and enhance the appearance of the model in viewportsTwo types of display modes:Entity mode targets entities by type (i.e. all curves are yellow, all quads are white)Group mode targets by group (i.e. default group is wireframe, bracket group is shaded

8、 yellow)Display type is global (affects all open viewports)Only one type of display mode may be used at a time ENTITY TYPE DISPLAYModify entity display propertiesModel Render Style applies to all entitiesShade Color applies to all entitiesColors of each Entity Type are unique for each entityShow or
