How to Import Files from SketchUp to SOLIDWORKS

SketchUp models can be brought into SOLIDWORKS, but the result usually depends on the file format and the quality of the SketchUp geometry. SketchUp files often import as mesh or surface data, so expect to inspect and repair the model before using it like a native SOLIDWORKS part.

Choose the best export format

If possible, export from SketchUp in a format SOLIDWORKS can import cleanly, such as STEP, IGES, STL, or another supported neutral format. STEP is usually preferred when the model can be exported as solid or surface geometry. STL is common for mesh models, but it is less editable.

Before exporting, check the model units in SketchUp. Unit mismatch is one of the most common import problems, especially when a building, fixture, or product model arrives much larger or smaller than expected.

Import the file into SOLIDWORKS

1. Open SOLIDWORKS.
2. Choose File > Open.
3. Select the exported SketchUp file or neutral file.
4. Check the import options before opening.
5. Open the file and wait for the import to finish.
6. Save the result as a SOLIDWORKS part or assembly.

Inspect the imported geometry

After import, check whether the model came in as a solid body, surface body, graphics body, or mesh body. A solid body is easier to edit. Mesh and graphics bodies may be useful for reference, but they are harder to modify with normal SOLIDWORKS features.

If the imported file is only a reference model, place it in an assembly and build clean SOLIDWORKS geometry around it. This is often faster and more reliable than trying to directly edit every imported face.

Repair or simplify the model

Use import diagnostics when available. Repair gaps, missing faces, and bad edges before building new features from the imported model. If the model is only needed as a reference, consider simplifying it so the SOLIDWORKS file stays responsive.

Large SketchUp models can contain many decorative faces that add weight without helping the engineering work. Remove furniture, scenery, tiny fasteners, or visual-only geometry if they are not needed.

Use imported SketchUp files carefully

Imported SketchUp geometry is often not built with manufacturing-grade CAD intent. Before using it for drawings, machining, fabrication, or assemblies, verify scale, units, faces, and important dimensions.

For customer or vendor files, keep the original export and document what repairs were made after import. That makes it easier to trace issues if the model is questioned later.
