Write Cache Select this check box to save cache files when native CAD files are converted. Generally, cache files

are much smaller than original CAD files, therefore, selecting this option does not take up too much disk space.

Clear this check box if you don’t want to save cache files.

Geometry Compression

Enable Select this check box to enable geometry compression when NWC files are saved.

Geometry compression results in less memory being required and therefore smaller NWC files.

Reduce Precision

Coordinates Select this check box to reduce the precision of coordinates.

Precision Specifies the precision value for coordinates. The larger the value, the less precise coordinates are.

Normals Select this check box to reduce the precision of normals.

Colors Select this check box to reduce the precision of colors.

Texture Coordinates Select this check box to reduce the precision of texture coordinates.

File Readers Node

DWF Page

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

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. To get twice the number of facets, double the value. To get half as many facets, halve the value.

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.

Extract Textures Select this check box to extract textures and environment maps associated with the file.

NOTE Environment maps are not set in the scene by default, and must be configured in Presenter manually.

When this check box is clear, the file reader ignores maps and textures.
