Use this page to adjust the options for the IFC file reader.

Conversion Method

Select an option from the drop-down list to specify the IFC conversion method used:

Representation Detail

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:

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, Navisworks adds more facets.

If the Max Facet Deviation is set to 0, then this function is ignored.

Show Spatial Hierarchy

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.

Use Property-Based Colors

Select this check box to convert and use property-based colors.

Tip: If an IFC file is predominantly black when loaded, clear this check box to revert back to using IFC-standard colors.

Convert Spaces

Select this check box to bring through and visualize spaces.

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

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. 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.

Convert Axes

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).

Create Selection Sets

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.

Convert Spaces/Openings/Storeys

When the Modern conversion method is selected, control the visibility of IFC entities by selecting an option from the drop-down list:
