Convert Features Indicates whether features are converted.

Convert Unknown Section into Rectangle Select this check box to convert unknown sections profiles into
rectangles with estimated parameters, but the scale may not be appropriate.
When this check box is clear, the file reader ignores unknown sections profiles.
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 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.

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.
