Bringing a SketchUp design into Autodesk Revit is often the first step for architectural teams migrating from a conceptual massing environment to a detailed documentation platform. This process allows designers to preserve the organic forms and rapid modeling workflow of SketchUp while unlocking the analytical and construction documentation power of Revit. When handled correctly, the imported geometry becomes a functional canvas for walls, floors, and parametric systems, transforming a simple sketch into a buildable intelligence model.
Preparing Your SketchUp Model for Import
The quality of the Revit model you receive is directly dependent on the preparation done inside SketchUp. Before exporting, it is essential to purge unused materials, components, and scenes to reduce file bloat and prevent unnecessary clutter. You should also ensure that all geometry is solid and clean, meaning there are no stray edges, overlapping faces, or misaligned planes that could cause import errors or visual artifacts in the target software.
Organizing Layers and Styles
SketchUp layers do not translate directly into Revit element categories, but they play a critical role in controlling visibility during the import process. You should organize your geometry by function—such as walls, furniture, or site elements—using layer names that mirror your intended Revit discipline. Utilizing the Styles manager to freeze complex textures or hidden geometry can also streamline the export, ensuring that only the necessary solid forms are passed through to the new environment.
Exporting from SketchUp
Once the model is clean, you must export it using the correct file format to preserve geometry and textures. The preferred method is to save the file as a DWG or FBX format, as these retain spatial reference and material information better than a basic 3D model. During the export wizard, you should select the appropriate units—usually either feet or meters—to match the Revit project template, preventing scaling issues that distort the spatial relationships of your design.
Choosing the Right Export Type
When given the option between a Partial Export and a Complete Export, you should generally opt for the Complete option to ensure all nested components are resolved upon import. If you are using FBX, adjusting the animation settings to disable keyframe export and focusing on static mesh data will yield better results for architectural visualization. Taking the time to configure these export settings prevents the need for rework once the file is inside Revit.
Importing into Revit
Revit provides several import options, and the choice between Import CAD and Link CAD determines how the data will behave in the project. Importing merges the geometry directly into the model, allowing you to modify it with architectural tools, while linking keeps the data external, which is useful for site contexts that change frequently. Regardless of the method, you should always place the imported file on a dedicated workset to manage collaboration and control visibility without affecting the core model.
Adjusting Units and Scaling
After initiating the import, the Import Units dialog box allows you to specify the source unit of the SketchUp file. If the geometry appears extremely large or small, you likely need to adjust the Scale Factor or choose a different unit interpretation. Correctly setting this parameter during the import process ensures that walls align with grid lines and dimensions reflect real-world measurements, saving hours of manual correction later on. Post-Import Cleanup and Modeling Once the SketchUp geometry is inside Revit, the real work begins. You will need to locate and fix issues such as misaligned floors, gaps in walls, or incorrectly oriented roofs using the visual feedback from section views. Architecture tools like Wall by Face or the Edit Boundary feature are essential for converting imported surfaces into intelligent elements that interact with schedules and construction documentation.
