Upload reference images, plans, textures and 3D models. Storage is unlimited on the subscription; only individual files have technical size limits.
Before you start
- Edit access to the project or workspace asset library.
Supported files and per-file limits
| Type | Formats | Max size per file |
|---|---|---|
| Images | PNG, JPEG, WebP | 25 MB |
| Documents | 50 MB | |
| 3D models | GLB, glTF | 200 MB |
These are per-file safety limits, not monthly quotas. There's no cap on how many files you upload or on total storage.
Steps
- Open the project's Files tab or the workspace Asset library.
- Drag files in, or choose Upload.
- Each file is uploaded directly to secure storage, then checked: type, size and checksum are verified, and previews are generated. The file shows Processing until checks pass, then Ready.
- Only ready files can be used in designs or shared.
Privacy and security
- Files are stored in private Cloudflare R2 storage. Each download uses a short-lived, signed link issued only after checking your access.
- Photo location (GPS) metadata is removed from images by default.
- Files are never public unless you deliberately share them.
- Removing someone's access stops them getting new download links.
Common problems
- "File too large." Compress the image, split a PDF, or reduce model texture sizes.
- Stuck on Processing. Large models can take a minute. If it fails, the file shows an error with a reason; try re-exporting it from the source application.
- Unsupported type. Convert to one of the formats above. For PDFs you want to trace, export the page as an image — see blueprint import.
