Transparency
Interactive Transparency Select this check box to render transparent items dynamically during interactive
navigation.
By default, this check box is clear, therefore, transparent items are only drawn when interaction has stopped.
NOTE If your video card does not support hardware accelerated OpenGL, selecting this check box can affect display
performance.
Detail
Guarantee Frame Rate Indicates whether the Autodesk Navisworks engine maintains the frame rate specified
on the
Speed tab of the File Options dialog box.
By default, this check box is selected, and the target rate is maintained while moving. When movement stops
the complete model is rendered.
If this check box is clear, the complete model is always rendered during navigation, no matter how long it takes.
Fill In Detail Indicates whether Autodesk Navisworks fills in any discarded detail when navigation has stopped.
Batch Fill Select this check box to render detail in chunks (batches) rather than gradually.
NOTE This check box is clear by default, as gradual rendering gives better results for most video cards.
Primitives
Point Size Enter a number from 1 through 9 to set the size (in pixels) of points drawn in the Scene View.
Line Size Enter a number from 1 through 9 to set the width (in pixels) of lines drawn in the Scene View.
Snap Size Enter a number from 1 through 9 to set the size (in pixels) of snap points drawn in the Scene View.
Enable Parametric Primitives Indicates whether Autodesk Navisworks dynamically renders parametric primitives
during interactive navigation.
Selecting this check box means the level of detail changes during navigation depending on the distance from
the camera.
Clear this check box to use the default representations of primitives; the level of detail stays the same during
navigation.
