How 3D models are stored depends on the data modeling status of the CDF project. See 3D models and project types.

​
Before you start

To upload and process 3D models, you need an account with the 3d:create, files:write, and files:read capabilities for your CDF project. See Assign capabilities to learn more. You also need:
  • Your CDF project name. You will use this as the [projectname] below.
  • The file name(s) of the model(s) you will be uploading. You will use this as the [filename] below.

​
Upload 3D models

1

Create a model that can hold several revisions

API reference: 3D models
2

Copy and make a note of the id field

Copy and make a note of the id field in the response. You will use this as the [modelId] below.
3

Create a file placeholder to make the file available for processing later

API reference: File content
4

Copy and make a note of the id field and uploadUrl

Copy and note the response id and uploadUrl. You will use them as [fileId] and [uploadUrl] in the next steps.
5

Upload the file

Google API reference: Perform resumable uploads
6

Create a versioned model and link the file from the first step to the revision

This also starts the processing of the model.
API reference: 3D model revisions
7

Monitor the processing of the model

API reference: 3D model revisions

​
Next steps

After uploading 3D models, you can add them to a scene to view and contextualize in CDF, or upload a revision to an existing model.
