Uploading 3D Models

Learn how to upload, organise, and manage your 3D model assets in Simplio3D. Understanding file limits and best practices will ensure your configurators load fast and look great.

Supported Formats

FormatExtensionRecommended ForNotes
glTF Binary.glbMost use casesPreferred format. Compact, includes textures.
glTF.gltf + .binMulti-file assetsRequires uploading associated .bin and texture files.
FBX.fbxCAD / animation exportsWidely supported by 3D tools; converted internally.
OBJ.obj + .mtlSimple geometryLegacy format; no animation support.
STL.stl3D printing modelsGeometry only, no materials or colours.
Best format: We strongly recommend .glb (glTF Binary) for the best balance of quality, file size, and compatibility. Export from Blender, 3ds Max, or any major 3D tool.

File Limits & Recommendations

LimitValueRecommendation
Maximum file size100 MBKeep models under 20 MB for fast loading.
Maximum polygonsNo hard limitTarget 50k-200k polygons for web. Use decimation for CAD models.
Texture resolutionUp to 4096x4096Use 1024x1024 or 2048x2048 for best balance.
AnimationsSupported in glTF/FBXKeep animation clips short and purposeful.

How to Upload

  1. 1Navigate to the Dashboard and click "Assets" in the sidebar.
  2. 2Click the "Upload" button in the top-right corner of the Assets page.
  3. 3Select one or more 3D model files from your computer. You can drag-and-drop files directly into the upload area.
  4. 4Wait for the upload and processing to complete. A thumbnail preview will be generated automatically.
  5. 5Once uploaded, you can rename the asset, add tags, and assign it to a category.

Organising with Categories

Categories help you organise large asset libraries. You can create categories like "Furniture", "Hardware", "Accessories", etc.

  1. 1Go to the Assets page and click the "Categories" tab or the folder icon.
  2. 2Click "New Category" and give it a descriptive name.
  3. 3Drag assets into categories, or select an asset and choose its category from the details panel.
  4. 4Use the category filter in the asset browser to quickly find models when building projects.

Optimisation Tips

Reduce Polygon Count

Use Blender's Decimate modifier or simplify meshes in your 3D tool before exporting. Target 50k-200k polygons for web.

Compress Textures

Use JPEG for diffuse maps and PNG for transparency. Avoid uncompressed TGA or BMP formats.

Clean Geometry

Remove hidden faces, internal geometry, and duplicate vertices. Apply transforms (location, rotation, scale) before export.

Proper Naming

Name your mesh objects descriptively (e.g., 'chair_seat', 'chair_leg'). These names appear in the Objects panel.

Common issue: If your model appears too small or too large, make sure you've applied scale transforms in your 3D software before exporting. In Blender, use Ctrl+A > Scale.
Model versions: When you upload a new model with the same filename as an existing one, Simplio3D automatically creates a version chain (v1, v2, v3…). You can then replace older versions in your projects while preserving all option block configurations. See for the full guide.
Modular projects: When preparing models for the Modular project type, ensure each module has its origin point set correctly. The origin determines where the module snaps and connects with others. See the for details.
