Sample Rate Specifies the frequency of points extracted from the input file.
Increasing the sample rate, reduces the number of points extracted. This has the effect of reducing the image
resolution, but increasing the speed with which the file is loaded.
Use Point Intensity Values Select the check box to extract intensity values from the input file.
When this check box is clear, the file reader ignores intensity values.
Use Point Color Values Select the check box to extract color values from the input file.
When this check box is clear, the file reader ignores color values.

Convert Features Indicates whether features are converted.
NOTE Converting a large number of features may have a negative impact on the loading performance.
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.
DGN Page
Use this page to adjust the options for the 3D DGN and PROP file reader.
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 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.
