Override Normals Normals control how objects appears when lit. By default, this check box is clear, and the

file reader uses the data provided in the VRML file, giving the most accurate visible results.

Select this check box if you want Autodesk Navisworks to ignore the normals, and generate the lighting data

instead, for example when the supplied model contains invalid lighting data.

NOTE Using this option is less accurate than using real lighting data in VRML files.

Override Orientation By default, this check box is clear, and the file reader processes the geometry information

in order indicated in VRML files, which can be clockwise or counter-clockwise.

When this check box is selected, the file reader ignores the order in VRML files, and processes the geometry

information counter-clockwise. This option is useful, if your model, when viewed in Autodesk Navisworks, has

holes or black areas in it.

Override Switch Statements By default, this check box is clear. This means, the file reader uses the default

behavior of the switch statements in VRML files.

For switch statements that are used in VRML scripting, related geometry is only converted if the corresponding

switch is turned on. As a result, you can get a mostly empty model in Autodesk Navisworks.

When this check box is selected, the file reader processes all switch statements, and brings through extra geometry.

NOTE Overriding Switch Statements can result, for example, in creating duplicate geometry if the switch statement

contains several ways to represent the same object.
