Use the free online SKP to STL Converter to load a SketchUp model, inspect and measure its geometry, then export the resolved model as an STL file directly in your browser.
SketchUp SKP and STL files serve different purposes. An SKP model can contain richer design information such as components, groups, materials and tags, whereas STL represents the model as a tessellated triangular surface. Converting SKP to STL therefore creates mesh geometry suitable for downstream workflows such as 3D printing, mesh inspection and manufacturing preparation.
Before converting, use the 3D preview to inspect the model from different angles and check the reported dimensions. The measurement tools can help verify important distances and diameters before export. If you only need to inspect the original SketchUp model without converting it, use the free online SKP Viewer.
It is good practice to check the model before creating an STL file. Confirm that the overall size is sensible, inspect the geometry for unexpected features and use wireframe or alternative viewing styles where they make the model easier to understand. Because STL is a mesh format, the exported file represents the resolved surface geometry rather than the full editable SketchUp model structure.
After conversion, open the result in the online STL Viewer to inspect the exported mesh independently. If the STL contains open edges, non-manifold geometry or other mesh problems, the online STL Repair tool can be used as the next step in the workflow.
STL is one of the most widely supported file formats in 3D printing workflows, which makes conversion useful when a design has been created or supplied as a SketchUp file. Converting the model does not by itself guarantee that the part is ready to print: wall thickness, mesh integrity, scale, orientation and the requirements of the intended manufacturing process should still be checked before production.
For models originating in engineering CAD rather than SketchUp, NS3D also provides a STEP to STL Converter and JT to STL Converter. Once a printable mesh has been prepared and sliced, the resulting machine instructions can be inspected using the online G-code Viewer.
Upload a supported SketchUp SKP file and inspect the resolved model in the 3D viewport. When you are satisfied with the geometry, select Convert to STL and then download the exported STL file.
Yes. The NS3D SKP to STL Converter is a free browser-based tool for converting supported SketchUp SKP geometry to STL, with no specialist CAD conversion software required.
No. Supported SKP files can be opened, inspected and converted directly in a compatible web browser without installing SketchUp on your computer.
No. The selected SKP file is processed locally in your browser and does not need to be uploaded to NS3D, helping keep engineering and design files on your own device.
Yes. Use the interactive 3D preview to rotate, pan and zoom the SketchUp model. You can also inspect model information, switch viewing styles, display wireframe geometry and check the model before STL export.
Yes. Supported geometry can be checked using vertex-snapped distance measurements, persistent drawing dimensions and diameter measurements before you create the STL file.
STL is widely used for mesh-based workflows such as 3D printing. After conversion, you can inspect the exported model in the NS3D STL Viewer or check the mesh using the NS3D STL Repair tool before manufacturing.
