VRML Page

Use this page to adjust the options for the VRML file reader.

Default Units

Specifies the type of units Autodesk Navisworks uses when opening VRML world files.

Faceting Factor

Enter the required value to control the level of faceting that takes place.

The faceting factor must be greater or equal to 0, where 0 results in the faceting factor being turned off. The default value is 1. When you double the value, you get twice the number of facets. When you halve the value you get half as many facets. Larger faceting factors result in more polygons to a model and larger Autodesk Navisworks files.

Max Facet Deviation

This setting controls the greatest distance between the edge of a facet and the actual geometry.

If this distance is greater than the Max Facet Deviation value, Autodesk Navisworks adds more facets.

If the Max Facet Deviation is set to 0, then this function is ignored.

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.
