How to Bring a SketchUp Model into Revit

In architectural design and construction, Revit and SketchUp are two very popular software programs. Revit focuses on Building Information Modeling (BIM), enabling detailed architectural design, construction documentation generation, and project management, while SketchUp, with its simple and intuitive interface, has become a valuable tool for architects and 3D model creators. Often, we may need to create a preliminary model in SketchUp and then import it into Revit for further refinement and documentation. So, how can we seamlessly import a SketchUp model into Revit? This article will detail the specific steps, considerations, and some practical tips for you.

Why Import SketchUp Models into Revit?

In the early stages of design projects, many designers prefer to quickly build conceptual models in SketchUp due to its intuitive and user-friendly operation. Once the design is complete, the SketchUp model can be imported into Revit for further design development, utilizing Revit’s powerful BIM features for detailed definition of building components, material allocation, and building information management. This combination allows the entire project to move more efficiently and accurately from conceptual design to detailed construction.

Moreover, some complex geometries and details from the SketchUp model can be used directly in Revit without the need for remodelling, saving a significant amount of time. Therefore, knowing how to efficiently import SketchUp models into Revit is a skill that every architectural designer should master.

Exporting SketchUp Models to a Revit-Supported Format

Revit cannot directly open .skp format SketchUp files, so we first need to convert the SketchUp model to a format that Revit can recognize, such as .DWG or .IFC. This ensures that most of the geometry and structural details are retained when the model is imported into Revit.

Exporting to DWG Format

1. First, open your SketchUp model and ensure that all geometries and components are correctly constructed. For particularly complex models, consider simplifying the structure and removing unnecessary details to facilitate smoother exporting and importing.

2. Select the “File” menu, click on “Export,” and then choose “3D Model.”

3. In the export settings, select the “AutoCAD DWG” format. Depending on your needs, you can choose different AutoCAD versions, such as 2013 or 2018, as these versions are compatible with Revit.

4. Click “Export” and choose the save path. Wait for the model to successfully export as a .DWG file.

By following these steps, we have successfully converted the SketchUp model into a Revit-supported format file. Next, we will import this file into Revit.

Importing SketchUp Models into Revit

Once you have exported the DWG file, you can proceed to import and adjust the model in Revit. Revit allows external CAD files to be inserted directly into a project and can recognize their geometric structures.

1. Open Revit and create a new project or open a working view in an existing project.

2. Click on the “Insert” tab, then select “Import CAD.”

3. In the pop-up window, select the previously exported DWG file. You can adjust the import units, layers, and positioning options to ensure the model displays correctly in Revit.

4. After importing, Revit will insert the CAD file as a linked or embedded model into the current view. This means you can continue modifying the model in Revit, and all geometric structures can be adjusted and defined.

Once the import is successful, you will see the SketchUp model fully displayed in the Revit workspace. You can use Revit's tools to move, rotate, and scale it to meet the current design requirements.

How to Optimize Imported Models in Revit

Although the model imported from SketchUp retains most of the details geometrically, it still requires some adjustments and optimizations to better align with Revit’s project structure and BIM features. Here are some practical optimization steps.

Use Revit’s Model Lines and Detail Lines

The imported SketchUp model is typically a solid geometric shape. If you need to convert it into components in Revit, such as walls, floors, or roofs, you can use Revit’s model lines and detail lines tools. These tools allow you to redraw Revit components based on the SketchUp model, facilitating subsequent BIM information entry and modifications.

Adjust and Group Model Elements

To facilitate model manipulation in Revit, it’s advisable to group and layer the imported model. For example, you can define different building parts (such as walls, windows, roofs, etc.) as Revit components or families, allowing for easy adjustments and modifications. Instead of treating the entire imported model as a single unit, this approach makes operations more flexible.

Reapply Materials and Textures

Since models exported in DWG format may lose some material and texture information, it is necessary to reset materials for the model after importing into Revit. Revit has a rich material library, allowing you to select appropriate materials based on design requirements and apply them to various components. For instance, you can add stone, wood, or metal textures to walls to make the model appear more realistic and detailed.

Common Issues and Solutions

Although importing from SketchUp to Revit is relatively straightforward, you may encounter some issues during the actual process. Here are some common problems and their solutions.

Missing or Incorrect Geometry

Sometimes, you may find that certain geometric structures are missing from the imported model or that the model does not display correctly in Revit. This is often due to the geometric complexity in the SketchUp model. You might try simplifying the polygon count and details of the SketchUp model before exporting the DWG file, or manually adjusting and fixing the imported geometry in Revit.

Material Mismatches

Due to differing material handling mechanisms between software, the imported model may lose its original material effects. In this case, you can reapply materials in Revit or use other 3D rendering tools to restore the material effects. Additionally, if the model requires a more realistic material appearance, consider using high-quality 3D texture resources to replace the original materials.

Importing SketchUp models into Revit is a common workflow, especially in architectural design and project management. By importing rapidly created SketchUp models into Revit, you can continue with detailed design and documentation generation, improving overall design efficiency. Throughout the process, ensuring that the export and import settings are correct can effectively reduce compatibility issues while maintaining the integrity and accuracy of the model.

After a successful import, use Revit’s various tools to optimize and adjust the model, such as grouping, resetting materials, and adding component information for better management and use in subsequent design and construction phases.
