Shaded Display Modes There are a lot of interesting ways to work with these
options. Experiment — you can't hurt anything. In an exercise later in this
chapter, you'll change a couple of the settings and see an effect in which rather
than parts fading when you activate a single component, the parts that you
aren't editing go to wireframe display.
Enabled This setting can be a little confusing because it affects the display of
parts that will be inactive in the assembly when you've activated another part.
For example, when you double-clicked the Shock Absorber earlier in the chap-
ter, you activated that part. The other parts appeared dimmed but still shaded.
If you had Shaded deselected in this tab, those inactive parts would appear as
wireframe.
Background This value controls the visibility of components that aren't
enabled in the assembly. Not having a component enabled gives it the appear-
ance controlled here and disables the ability to select it in the assembly.
Minimum Frame Rate (Hz) When you have limited graphic or system-memory
capacity, Inventor may degrade the quality of the model image while rotating or
zooming. The higher this value is, the more quickly Inventor will degrade the
detail of the assembly in order to display it at the selected frame rate. This can
be a great setting to explore when you're working with extremely large
assemblies.
Show Hidden Model Edges as Solid Deselecting this check box changes the
display of hidden edges in the wireframe view from solid lines to hidden lines.
3D Navigation The Reverse Direction option under Zoom Behavior controls
the direction of the wheel-button zoom. This option was added for AutoCAD
users who prefer the effect of moving the camera, as mentioned earlier. You can
also set your default values for the ViewCube or Navigation Wheels here.
The Hardware Tab
If you're using Windows 2000 or XP, you can use this tab to select whether the
graphics engine in Inventor is based on OpenGL or Direct3D. Vista users will see
that there is no OpenGL option.
Notice the Use Software Graphics option. If you experience frequent crashes,
try running with this setting for a while. Your performance will be greatly lim-
ited; but if you fi nd that your system is more stable that way, it means you need
to fi nd an approved driver for your graphics card or update your graphic hard-
ware. You can fi nd more information about graphics drivers under the Help fl y-
out menu under the heading Additional Resources.
