In order for the Autodesk integration to work, Viio application needs to be added in the Account Admin as a custom integration.
Below is the step-by-step instruction to activate API access to Account Admin.
Log into your BIM 360 or ACC and go to Account Admin >> BIM 360 Admin
And after that go to BIM 360 Admin:
2. If you have more than one account, choose one you want to integrate your application from the pull down menu at the top.
3. Go to “SETTINGS”.
4. You should see another layer of tabs within the SETTINGS. Among them is “Custom Integrations” tab (the third one from the left), which is visible only if you are the account owner of license types mentioned above.
5. Choose both Account Administration and Document Management
6. Click the checkbox to acknowledge the Account ID you are enabling application usage for and copy the BIM 360 Account ID shown.
7. Add the Viio app Forge ID: eznFXRgyf80AX2s4knK02iEh80UTrmIf
and fill in the Application name: Viio
Once this is done, you can go to the Integration Center, select the Autodesk integration and fill in your BIM 360 Account ID and Region.
And this is it, all set :)
