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.
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.

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

Max Facet Deviation This setting controls the greatest distance between the edge of a facet and the actual

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.
Convert Hidden Items Select this check box to convert hidden entities in DGN files. They are automatically
marked as hidden by Autodesk Navisworks.
When this check box is clear, the file reader ignores hidden items.
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.
Convert Lines and Arcs Select this check box to convert lines, splines, curves, arcs, circles, or ellipses in DGN
files.
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.
Convert Text Select this check box to convert text into quick properties in Autodesk Navisworks.
When this check box is clear, the file reader ignores text in DGN files.
Default Font Indicates which font to use for the converted text.
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”.
Convert References Select this check box to convert reference files in DGN files.
When this check box is clear, the file reader ignores reference files.
Ignore Unres. References Select this check box to ignore unresolved reference files in DGN files.
