The GD&T callouts area lets you control the display of GD&T callouts within an imported CAD model. It helps reduce screen clutter by making such callouts temporarily hidden as they reach or approach a view angle parallel to your current view angle.
Do not confuse these GD&T callouts with the Feature Control Frame dimensions that are created inside PC-DMIS. The GD&T callouts are essentially CAD objects themselves. There were not created inside PC-DMIS. Rather, they were created by the CAD software used to create the model and are stored with the model.
Always display - This option indicates that the callouts will always be displayed, regardless of the viewing angle of the screen.
Hide when near parallel to view - This option indicates that the callouts will be hidden when they cross a threshold of degrees parallel to your view angle. This option is disabled when Always display is selected.
Degrees parallel threshold - This box lets you specify the threshold of degrees parallel to your view angle used to hide the callouts.
Movie Demo
The small movie below demonstrates the callouts being hidden once they reach the threshold. In this case the threshold is initially set for 15 degrees (the default is 30) and then later set to 45 degrees.
