SketchUp Free is a browser-based version of the popular 3D modelling application that has been used by architects, designers and hobbyists for many years. Its intuitive drawing tools and straightforward interface make it an excellent choice for OpenSim builders who want to design buildings, furniture and other structures without the steep learning curve associated with more advanced modelling software.

The application allows users to construct detailed 3D models using simple push-and-pull modelling techniques, making it particularly suitable for creating houses, shops, public buildings and architectural features. Once completed, models can be exported and refined in Blender before being converted into Collada (.DAE) format for import into OpenSim.

One of SketchUp Free’s greatest strengths is its ease of use. Beginners can often begin producing useful models within a very short time, while more experienced designers can create surprisingly detailed projects using its extensive range of drawing and editing tools. The browser-based version also removes the need to install large software packages, allowing projects to be created from almost any computer with internet access.

The software integrates well into an OpenSim workflow, particularly when used alongside Blender for optimisation and texture preparation. Many builders use SketchUp for rapid architectural design before completing the final optimisation process in Blender ready for upload into their virtual regions.

Whether you are designing a family home, a commercial building or an entire town, SketchUp Free provides a fast and accessible way to develop architectural models that can become part of rich and immersive OpenSim environments.
