Revit Page

Use this page to adjust the options for the Revit File Reader.

Convert Element Parameters

Specifies how Revit parameters are read. Select from the following options:

• None - the file reader does not convert parameters.
• Elements - the file reader converts parameters for all found elements.
• All - the file reader converts parameters for all found elements, including the referenced elements. As a result, extra property tabs are available in Autodesk Navisworks.

Convert Element Ids

Select this check box to export the ID numbers for each Revit element.

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

Try and Find Missing Materials

When this check box is selected (the default option), the file reader looks for a match for the materials missing from the export.

Note: If any inappropriate materials are applied to the model geometry as a result, clear this check box to fix the problem.

Coordinates

Specifies whether to use shared or internal coordinates for file aggregation. By default, shared coordinates will be used, which are established in Revit.

• Project Internal
  Loads files with an origin of 0,0,0 using Revit Project North.

  Note: This is the same as the Revit Project Base Point.
• Shared

  Loads files using the shared coordinates specified in the Revit file. See the About Shared Coordinates topic in the Revit help for more information.

  Navisworks converts the shared coordinates in to a transform that is applied to the model, reflecting any X,Y,Z offset from origin, and any rotation to True North specified in Revit.

Note: If models from Revit appear misaligned when using the Shared option, it may be because the shared coordinates in a Revit host model have not been published to any linked models. This causes the linked models to use Revit's default Project Internal coordinates, and therefore appear misaligned in Navisworks. It is recommended that model authors agree on a coordinate system before creating and sharing models to avoid this. Alternatively, the model can be repositioned in Navisworks without affecting the coordinates in Revit, by adjusting the units and transforming the model, or moving the model using the transform tools. Once you have aligned the models as required, save the file as an NWF so that the transforms are reapplied when the file is opened.

Convert Element Properties

Select this check box to convert the Properties of each element in your Revit (RVT) file into Autodesk Navisworks (NWC) Properties. Leave this check box clear if you want to retain the original Revit Properties.

Convert Lights

Check this option if you want to export the lights contained in your Revit file into Navisworks. By default, this check box is clear.

Convert URLs

Indicates whether URL property data is converted. By default, this check box is selected and the hyperlinks are supported in the converted file.

Convert Linked Files

Revit projects can embed external files as links. When this check box is selected, linked RVT files will be included in the exported NWC file. By default, this check box is clear.

Note: Only linked RVT files can be exported; linked dwgs and any other file formats are not supported.

Convert Linked CAD formats

Revit projects can embed external files as links. When this check box is selected, linked CAD files such as DXF, DGN, SAT and Sketchup format will be included in the exported NWC file. By default, this check box is clear.

Convert Construction Parts

When using the Revit 2022 Construction Modelling and Assemblies feature, you have an option of exporting either the original object or construction parts into Autodesk Navisworks. Select this box if you want to export the construction parts; clear this check box if you want to export the original object.

Divide File into Levels

Indicates whether the Revit file structure is split into levels on the Selection Tree. By default, this check box is selected, and Revit files are organized by File, Category, Family, Type, and Instance. See Divide File into Levels.

Convert Room Geometry

When using Revit 2022, you have the option of using either the original room geometry or converting it into construction sub-parts in Autodesk Navisworks. By default, this check box is selected and room geometry is converted into sub-parts. Clear the check box if you want to keep the original room object.

Convert Room as Attribute

Indicates whether room attributes are supported. By default, this check box is selected, and data for each room converts into a single shared room attribute.

Convert

Specifies how to convert and load viewing options for Revit files. Select from the following options:

• Navisworks view

  The default view. To use the Navisworks view, save an RVT file in Revit and use "Navis" in the name of the 3D view. If you do not use this option, the Revit First 3D View is loaded.

• First 3D view

  Loads the elements visible in the Revit First 3D View.

• Entire project

  Loads the whole project.

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.
