Universal Importer is a SketchUp Ruby plugin designed to streamline workflow by importing various 3D file formats directly into the software. This extension functions as a bridge for interoperability, allowing users to bring diverse 3D file types into a native SketchUp environment. It leverages the Assimp library to handle common formats including FBX, OBJ, DAE, 3DS, glTF, and PLY. Beyond simple file translation, the tool includes a dedicated feature for polygon reduction during the import process. This is critical for managing heavy geometry from other modelling packages, ensuring that high-poly assets remain performant within the SketchUp viewport. The interface is designed to integrate seamlessly with the existing menu structure, providing a unified solution for external asset management.

The download is a 33.2 MB file containing .ZIP files.

To utilise this plugin, install the extension via the SketchUp Extension Manager. Once loaded, access the import dialogue to select your target file. Users can define parameters for geometry processing, including the optional polygon-reduction step, which helps maintain model responsiveness. This tool is essential for teams working in heterogeneous software environments, enabling the rapid conversion of complex assets without needing intermediate software for cleaning or re-exporting geometry before it enters the main project file.

Professional designers and visualisers rely on this tool when coordinating models across different platforms in architectural and interior design projects. It is particularly useful for importing furniture components or site context from third-party libraries that provide formats like OBJ or FBX. By reducing polygon counts during the import phase, the plugin helps keep project files light and manageable during the schematic design and design development stages. It is a vital utility for any office that frequently collaborates with external consultants using non-native 3D modelling applications.
