convert it. By default, it writes a cache file in the same directory and with the
same name as the CAD file, but with the .nwc extension, for speeding up the
opening of this file in future.
Caching
Read Cache Select this check box to use cache files when Autodesk Navisworks
opens native CAD files.
Clear this check box if you don’t want to use cache files. This ensures that
Autodesk Navisworks converts native CAD files each time they are opened.
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.
