When DGN files are appended together with this check box selected, their global origins are positioned in the
same place.
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 exporter ignores hidden items.
Convert Lines and Arcs Select this check box to convert lines, splines, curves, arcs, circles, or ellipses in DGN
files.
Convert PDS Data Select this check box to read object information from Intergraph's Plant Design System
™
while converting the DGN files.
PDS information is read from Intergraph's DRV files. The file exporter looks for a DRV file with the same base
name as the DGN file in the same directory.
When this check box is clear, the file exporter ignores PDS data.
Convert References Select this check box to convert reference files in DGN files.
When this check box is clear, the file exporter ignores reference files.
Convert Text Select this check box to convert text into quick properties in Autodesk Navisworks.
When this check box is clear, the file exporter ignores text in DGN files.
Convert TriCAD Data Select this check box to read object information from Triplan’s TriCAD
™
while converting
DGN files.
When this check box is clear, the file exporter ignores TriCAD data.
Convert TriForma Data Select this check box to read object information from Bentley’s TriForma
™
while
converting DGN files.
When this check box is clear, the file exporter ignores Tri-Forma data.
Default Font Specifies default font used to display converted text in Autodesk Navisworks.
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.
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.
