General

Graphics Performance

Rendering quality	Select a value from 1 to 7, where 1 is the lowest quality and 7 is the highest quality. Select a low number to increase the speed of the application; select a high number to increase the quality of the graphics. Increasing graphics quality may lower the responsiveness to actions in the graphics window. If you notice a delay when working with your design, modify this option to increase application speed.
Recalculate Rendering	Select this option to update the 3D display in the graphics window. Sometimes when a model is modified the graphics can become misaligned. The actual geometry maybe still accurate, but the selected rendering quality may become too low to maintain the visual appearance. Click Recalculate Rendering to bring the model back into alignment visually.
Anti-aliasing	The amount of smoothing applied to geometry rendering in the Design window.
