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 this value. To get half as many facets, halve this
value. Larger faceting factors result in more polygons to a model and larger Autodesk Navisworks files.
Ignore Unres. References Select this check box to ignore unresolved reference files in DGN files.
If this check box is clear, the file exporter attempts to convert all reference files, and presents you with a dialog
box to find any unresolved reference files at a run time.
Material Search Paths Enter a semi-colon separated list of paths to the MicroStation palette (.pal) and material
(.mat) files. These paths are used by the file exporter to convert MicroStation materials.
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.
Merge Lines and Arcs Select this check box if you want to reduce the complexity of the model in the Selection
Tree by interpreting adjoining lines with the same color, level, and parent as a single item.
Clear this check box if you want to leave these elements as separate items in Autodesk Navisworks.
Split Lines This option instructs the file reader to ungroup polyline objects. As a result, line elements are split
into separate nodes for each segment of the line.
Use this option when you need to enhance clash detection analysis. By default, Clash Detective treats
multi-segment entities as a single object, report one clash for each object pair. Ungrouping polyline objects
means that each line segment can be clashed independently from other segments of the line. As a result, all
potential clashes are reported, and not just the first one found.
IMPORTANT In order for this function to work properly, you must clear the Merge Lines and Arcs check box, as it
takes priority over the Split Lines option. Additionally, you need to set the Model ➤ Performance ➤ Collapse on
Convert drop-down to None, otherwise the polyline objects will be collapsed into a single geometry node.
Shape Merge Threshold Specifies the number of vertices for MicroStation shapes.
If the number of vertices is less than or equal to the Shape Merge Threshold value, Autodesk Navisworks merges
all shapes on the same level or in the same cell and with the same color into a “Shape Set”.
Show Hidden Items Select this check box, if you want to display all entities in converted DGN files, irrespective
of whether they are hidden or not.
NOTE To use this option, you must select the Convert Hidden Items check box.
TriForma Dataset Search Paths Enter a semi-colon separated list of paths that the file reader uses to locate
Triforma data set files. You must include the paths to user-defined datasets.
Use Level Symbology Select this check box to enable the level symbology from MicroStation. This makes items
in Autodesk Navisworks take their color from level rather than use the default element color in MicroStation.
Use Materials Indicates whether MicroStation's materials are exported and assigned to elements.
Select this check box to assign the same textures, diffuse, ambient, and specular colors to the elements as in the
MicroStation scene.
Clear this check box to assign the same colors to the elements as in the MicroStation scene.
View Number Enter the required value to selects a specific view for loading. The file exporter uses the level
visibility of this view when converting items.
For example, enter 0 to use the first active view.
