To set the faceting factor on reading CAD files go to the Options Editor (click
Options, expand the File Readers node, and choose the relevant file reader page).
max facet deviation Maximum facet deviation is used in conjunction with faceting factor
to ensure that larger objects, with too large a deviation from the original, have additional
facets added. If a difference greater than the entered value is found in a model it adds more
facets. The values are measured in the model units.
Where d is greater than the maximum faceting deviation value, more facets are added to
the object.
If the max faceting deviation is set to 0, then this function is ignored and just the faceting
factor is used.
published data files (NWD) Published NWD files are useful when wanting to take a snapshot
of the model at a certain time. All the geometry and review information is saved into the
NWD file and cannot then be changed. Published NWD files can also contain information
about the file, as well as being able to be password protected and time-bombed for security.
These files are also very small, compressing the CAD data by up to 80% of the original size.
Published NWD files are useful when issuing models for viewing by others with the Autodesk
Navisworks Freedom 2012 free viewer, as well as being appendable themselves into Autodesk
Navisworks to build up a larger scene.
review files (NWF) Review files are useful when using the native CAD files appended into
Autodesk Navisworks. They store the location of the appended files, along with any design
reviews made in Autodesk Navisworks, such as comments, redlines, viewpoints, animations
and so on.
If a group of files is appended into a Autodesk Navisworks scene, and saved as an NWF file,
then on re-opening this NWF file later, once the original CAD files have been changed, the
updated CAD files will be loaded into the scene for review.
shape merge threshold MicroStation shapes are polygons that can have 3 or more vertices.
Theyre often used to model more complex objects which can waste memory. So, Autodesk
