DWG/DXF Page

Use this page to adjust the options for the DWG/ DXF 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 the value. To get half as many facets, halve the 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.

Split by Color

Compound objects can be split into parts based on their color. Select this check box if you want to use this functionality.

For example, a window object from Architectural Desktop can be split into a frame and a pane. If this check box is clear, you can only select the window object as a whole, whereas if you select this check box, you can select the individual pane and frame.

Note: Autodesk Navisworks names parts of compound objects after their color.

Default Decimal Units

Selects the types of units Autodesk Navisworks uses to open DWG and DXF files that were created with decimal drawing units.

Note: DWG and DXF files do not specify the units they were created in. To adjust the units in Autodesk Navisworks, use the Units and Transform option.

Merge 3D Faces

Indicates whether the file reader interprets adjoining faces with the same color, layer, and parent as a single item in the Selection Tree.

Clear this check box to keep the entities as separate items in the Selection Tree.

Line Processing

Specifies how the file reader processes lines and polylines. Select one of the following options:

• Merge Lines by Color. This option merges any lines on the same layer or on the same proxy entity that match by color. Use this option when you want more efficient file processing and navigation.
• As Provided. This option reads lines and polylines the same way as they are specified by the original DWG.
• Separate All Lines. This option splits line elements 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, reporting 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. The Clash Detective feature is available for Autodesk Navisworks Manage users only.

  Note: In order for this function to work properly, you need to set the ModelPerformanceCollapse on Convert drop-down to None, otherwise the polyline objects will be collapsed into a single geometry node.

Convert Off

Select this check box to convert layers that are switched off in DWG and DXF files. They are automatically marked as hidden in Autodesk Navisworks.

When this check box is clear, the file reader ignores switched off layers.

Convert Frozen

Select this check box to convert layers that are frozen in DWG and DXF files. They are automatically marked as hidden in Autodesk Navisworks.

When this check box is clear, the file reader ignores frozen layers.

Convert Entity Handles

Select this check box to convert entity handles, and attach them to object properties in Autodesk Navisworks.

When this check box is clear, the file reader ignores entity handles.

Convert Groups

Select this check box to retain groups in DWG and DXF files; this adds another selection level to the Selection Tree.

When this check box is clear, the file reader ignores groups.

Convert XRefs

Select this check box to convert any external reference files contained within the DWG file automatically.

Clear this check box if you want to append files in Autodesk Navisworks later yourself.

Merge XRef Layers

Select this check box to merge the layers in external reference files with layers in the main DWG file in the Selection Tree.

Clear this check box to keep the external reference files separate from the main DWG file in the Selection Tree.

Convert Views

Select this check box to convert the named views into Autodesk Navisworks viewpoints.

When this check box is clear, the file reader ignores views.

Convert Points

Select this check box to convert points in DWG and DXF files.

When this check box is clear, the file reader ignores points.

Convert Lines

Select this check box to convert lines and arcs in DWG and DXF files.

When this check box is clear, the file reader ignores lines.

Convert Snap Points

Select this check box to convert snap points in DWG and DXF files.

When this check box is clear, the file reader ignores snap points.

Convert Text

Select this check box to convert text in DWG and DXF files.

When this check box is clear, the file reader ignores text.

Default Font

Indicates which font to use for the converted text.

Convert Point Clouds

Select this check box to convert the AutoCAD Point Cloud entities. This applies to DWG Loader version 2011 or later. ReCap point clouds are only supported for the most recent DWG Loader version. Earlier versions will ignore the point clouds or display proxy graphics (often as a wireframe box).

When this check box is clear, the file reader ignores point clouds.

Point Cloud Detail

Specifies how much detail to extract from the point cloud. The valid entries are between 1 and 100, where 100 = all the points, 10 = about 10% of the points, 1 = about 1% of the points. This does not apply to ReCap point clouds.

Use Point Cloud Colors

Controls the point cloud colors. Select this check box to use color values for the points in the point cloud.

When this check box is clear, any color values for the points in the point cloud are ignored and the normal AutoCAD color for the entity is used. This option is useful if the specific colors stored are too dark or meaningless. This does not apply to ReCap point clouds.

DWG Loader Version

Specifies which DWG loader version to use when opening a DWG file linked to a point cloud. This option defines which version of ObjectDBX to use when loading AutoCAD files. You can select support for the correct version of object enablers that can be used within the file. To view DWG files in orthographic mode, ensure the DWG Loader Version matches your version of Navisworks.

Attention: When you modify these settings, you need to restart Autodesk Navisworks to apply the changes.

Use ADT Standard Configuration

Select this check box to convert geometry and materials in DWG files using the Standard display configuration.

Clear this check box to convert geometry and materials accordingly to whether they are displayed in the currently saved display configuration.

Convert Hidden ADT Spaces

Indicates whether space objects that lack any visible 3D geometry in DWG files are converted (for example, objects that lack floor or ceiling thicknesses).

Selecting this check box results in corresponding hidden objects appearing in Autodesk Navisworks.

Note: This option does not affect the normal behavior of space objects that have visible 3D geometry in DWG files.

Material Search Paths

Autodesk Navisworks automatically searches the default Autodesk material paths.

Use this box to specify additional paths to texture files used in Autodesk Architectural Desktop materials. Separate the paths with semi-columns.

Render Type

Specifies the render style used for objects when loading DWG files.

Selecting Automatic means Autodesk Navisworks uses the render style saved in DWG files.

If geometry is not correctly displayed, adjust the render style with one of the following options: Rendered, Shaded, or Wireframe.

Convert Autodesk Material

Select this option to convert Autodesk materials. The file reader will convert Autodesk materials, if they are available. This is the default option. When this check box is clear, the file reader will not convert Autodesk materials.

Restores the default values.
