Use this page to adjust the options for the IFC file reader.
Select an option from the drop-down list to specify the IFC conversion method used:
Legacy - to use the Navisworks converter. This is a legacy method which may not convert all IFC files correctly, but does process files more quickly. This method will not be developed further.
Modern - to use a Revit-based converter. This method produces better quality conversions, but may take longer to process files. It is compatible with the IFC add-in available from the Autodesk App Store. This method will be developed further for future releases.
v3 - to use the recommended Revit-based converter (default). This method processes files more quickly than the Modern method. It is compatible with the IFC add-in available from the Autodesk App Store. This method will be developed further for future releases.
Specifies the level of visual representation of IFC elements.
IFC elements can have multiple visual representations, such as bounding boxes (simplest), lines, styled lines, polygons, and styled polygons (most complex). Loading and showing all of these representations can lead to cluttered visuals and memory overheads.
Select from the following options:
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, Navisworks adds more facets.
If the Max Facet Deviation is set to 0, then this function is ignored.
Select this check box to show IFC model as a tree structure in the Selection Tree.
Clear this check box to show IFC model as a simple list of elements in the Selection Tree.
Select this check box to convert and use property-based colors.
Select this check box to bring through and visualize spaces.
When this check box is clear, the file reader ignores spaces.
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. When you double the value, you get twice the number of facets. When you halve the value you get half as many facets. Larger faceting factors result in more polygons to a model and larger Navisworks files.
Select this check box to convert object axes when importing IFC files.
When this check box is clear, object axes are excluded, improving the viewing and navigation experience (default).
Select this check box to automatically create selection sets when appending IFC models to Navisworks (default).
When this check box is clear, selection sets are not created.
When the Modern conversion method is selected, control the visibility of IFC entities by selecting an option from the drop-down list:
