What is the process to convert Google sketchup files into low poly 3D format?

Converting Google SketchUp (now Trimble SketchUp) files into a low-poly 3D format typically involves simplifying the geometry of the model to reduce its polygon count. Here's a general process you can follow:

Method 1: Using SketchUp's Simplification Tools

1. Open your SketchUp model:

   • Launch SketchUp and open the model you want to convert.

2. Simplify the Geometry:

   • Use the "Decimate Geometry" tool or "Simplify Contours" tool if available in SketchUp. These tools may help reduce the complexity of the model by removing unnecessary vertices and edges.

3. Manually Reduce Detail:

   • Manually remove unnecessary details and simplify the geometry by merging coplanar faces, reducing the number of edges, and eliminating fine details that may not be needed.

4. Export as a Low-Poly Format:

   • Export the simplified model in a 3D format suitable for low-poly representation, such as Collada (DAE) or FBX. Go to "File" > "Export" > choose the desired format.

Method 2: Using Third-Party Software

1. Export the SketchUp Model:

   • Export your SketchUp model in a widely supported 3D format, such as Collada (DAE) or FBX.

2. Import into 3D Modeling Software:

   • Use a 3D modeling software that offers polygon reduction tools. Blender is a popular free and open-source option. Import your SketchUp model into Blender or another 3D modeling application.

3. Apply Polygon Reduction:

   • Use the built-in polygon reduction tools or plugins available in the 3D modeling software to simplify the geometry. This often involves adjusting settings to control the level of reduction.

4. Export as Low-Poly Format:

   • Once you've reduced the polygon count to your desired level, export the model in a low-poly format, such as FBX or OBJ.

Method 3: Using Online Services

1. Export the SketchUp Model:

   • Export your SketchUp model in a common 3D format like Collada (DAE) or FBX.

2. Use Online Simplification Tools:

   • There are online services that offer automatic polygon reduction for 3D models. Upload your exported model to one of these services, and they will often provide simplified versions for download.

3. Download Low-Poly Model:

   • After the online service has processed your model, download the simplified, low-poly version.

Notes and Tips:

• Backup your original model: Before applying any modifications, it's always a good practice to create a backup of your original SketchUp model.

• Check Textures and Materials: Simplifying geometry might affect textures and materials. Be sure to check and adjust them accordingly after the simplification process.

• Adjust Settings: When using third-party tools or online services, explore and adjust settings to find the right balance between reducing polygon count and maintaining the overall appearance of your model.

The specific steps may vary based on the tools and software you choose to use, so always refer to the documentation of the software or service for detailed instructions.
