Task 3 – Translate Source File

To extract geometry from a model, you must first translate the model to a viewer-friendly format. While this tutorial translates the model to SVF, you can just as well translate to SVF2. The procedure to extract geometry is identical for both formats.

Start a translation job

For this task, you use the Base64-encoded URN of the source file. In the previous task, Postman saved this URN to the variable t6_ossEncodedSourceFileURN, which you use in the next request.

1. In the Postman sidebar, click Translate to SVF > Start a Translation Job. The request loads.

2. Click the Body tab and take note of the JSON payload.

   

   Note the name of the Inventor assembly file in the JSON body.

3. Click Send. If the request is successful, you should see a screen similar to the following image.

   

   Note the urn parameter in the JSON response. The value of this parameter is the URL-safe Base64 encoded URN of the source file. A script in the Tests tab, saves this value to a variable named t6_url_safe_urn_of_source.

Check status of translation job

When you kick off a translation job, it takes time to complete. There are two ways to check if the translation job is done:

• Periodically check the status of the translation job.

• Set up a webhook to notify you when the job is done.

For this tutorial, you check the status of the translation job. For more information on webhooks, see the documentation on Model Derivative webhook events

1. In the Postman sidebar, click Translate to SVF > Check Status of Job. The request loads.

   

   Notice how the URL-safe Base64-encoded URN of the source file is used as a URI parameter (the t6_url_safe_urn_of_source variable).

2. Click Send. A screen similar to the following image is displayed.

   

   Repeat this step until the progress attribute becomes complete, as shown in the image.
