To import Autodesk Revit files

InfraWorks 360 uses cloud import to add RVT data to a model. You do not need to have Revit installed.

1. Do one of the following:
   • Drag and drop the .rvt file onto the model.
   • Click .
2. On the Data Sources panel, do the following:
   • Click (Add File Data Source).
   • Click Revit RVT.
   • Open the model file.
3. In the Data Sources panel, double-click the imported feature.
4. In the Data Source Configuration dialog box, if the Geo Location tab displays a warning icon, click it and specify the coordinate system for the model.

   Generally, InfraWorks 360 can position the incoming data automatically, based on the data itself.

5. To create a tooltip for the model, click the Tooltip tab.

   For more information, see Create Tooltips During Import.

6. Click the 3D Model tab to adjust the model.

   The preview display on this tab shows how the 3D model is affected by your settings. Those settings include:

   • Render Detail — Use these settings to control how models of different sizes and levels of complexity are represented in the model.
     • Simplify Model reduces the number of triangles that define the shape of the model, which reduces detail.
     • Model Handling specifies how the model will be rendered. Try the Auto-adjust setting first, and make further adjustments only if necessary.
   • Model Repair — Use these settings if the model does not appear as expected.

   For details on the Model Handling and Model Repair settings, see the Advanced Tips section below.

7. Click Close & Refresh to apply your changes and see the results in the model.

Advanced Tips

You can import a Revit file from your local computer or from a network.

Protein textures and user-defined texture materials are imported.

If you need to adjust the model handling, use these guidelines:

Auto-adjust	InfraWorks 360 determines the settings for the 3D model.	If the automatic setting applies LOD, you can change the LOD Distance setting by selecting LOD explicitly and then adjusting the LOD Distance.
Direct Display	InfraWorks 360 applies your settings for Simplify Model and the options under Repair Model, but does not adjust how the model is rendered.	Use this setting if the model uses a small number of triangles to define its shape, for example, a house with little detail.
Use LOD	InfraWorks 360 uses LOD (Level of Detail) to generate a series of simplifications, assigning the best one based on viewing distance. If you select this option, specify the LOD Distance.	Use this setting if the model has a great deal of detail with many triangles defining its shape, for example, a detailed city furniture model. LOD reduces the complexity of a 3D model as it moves away from the camera. The number of triangles defining the model are reduced to one quarter their previous value at each transition distance. (The transition levels are determined by the application.) The LOD Distance setting represents the first transition distance. At distances smaller than this, the model appears with full detail. Note: If you reduced the value for Simplify Model, the level of detail starts with the reduced value.
Tile	The surface of a model is tiled to display graphics smoothly and efficiently. When a single object spans multiple tiles, its display can be erratic. If the object is on the periphery of the visible area of the model, it may not appear at all, or it may suddenly appear when the viewer pans closer to it. The Tile setting avoids these issues by permanently attaching the 3D model to multiple tiles. It does not affect your ability to view or manipulate the model.	Use this setting if the model has a large bounding box, and if much of the bounding box is empty. For example, a model of a bridge might span several kilometers, and the bounding box would contain a lot of empty space. The model will be imported in such a way that it can span multiple tiles in the model effectively.

Use the Repair Model settings to adjust the model when it does not appear as expected.

• Invert Orientation — Inverts the direction of the face normals that make up each surface of the model.
• Invert Transparency — Makes the transparent areas of the model solid and the solid areas transparent.
• Invert Up Axis — Flips the model upside-down.
• Flip Y and Z — Controls whether the 'up' axis runs along the Y or Z axis. Some applications use the Y axis as the 'up' direction while others use the Z axis.
• Texture Blend Mode — Controls how texture images are combined with surface colors and lighting. Modulate tends to darken images while Decal lightens them.

After you import Revit data, the screen refresh time will vary depending on the size of the imported file. For a building system that is smaller than 10 Mb, to import all exterior elements takes less than 40 seconds. If the size is closer to 200 Mb, refreshing can take as much as fifteen minutes.

If you change the coordinate system, make sure to specify the coordinate system of the incoming data (not the coordinate system of the model). If the imported data uses a different coordinate system than your model uses, InfraWorks 360 will transform the data to the model's coordinate system, without changing the original data store.
