Access Cloud Models with Design Automation

peter_sylvester — Sun, 09 Feb 2025 14:33:12 GMT

I have a Revit DA application where I am trying to access an ACC model.

I've done as described in the docs.

My WorkItem in Postman looks like:

{ "activityId": "{{dasNickName}}.NVCMActivityTXT+testTXT", "arguments": { "NVCMParams" : { "url": "data&colon;application/json, [{'Region': 'US', 'ProjectId': '062b8c8b-d33b-473f-9760-1e811629071a', 'ModelGuid': 'c20b5561-4f6b-4eb1-b9b7-84bfe163ff7a'}, {'Region': 'US', 'ProjectId': '062b8c8b-d33b-473f-9760-1e811629071a', 'ModelGuid': 'c20b5561-4f6b-4eb1-b9b7-84bfe163ff7a'}]" }, "result": { "url": "urn:adsk.objects:os.object:{{ossBucketKey}}/{{ossOutputFileObjectKey}}", "verb": "put", "headers": { "Authorization": "Bearer {{dasApiToken}}" } } }, "adsk3LeggedToken" : "{{adsk3LeggedToken}}" }

{{adsk3LeggedToken}} is a valid token that when used in other calls works perfectly (e.g. Get Hubs, Projects... etc)

Still, when trying to open a cloud model I am getting the following error.

Autodesk.Revit.Exceptions.RevitServerUnauthenticatedUserException: You must sign in to Autodesk 360 in order to complete this action. [02/09/2025 14:20:40] at Autodesk.Revit.DB.ModelPathUtils.ConvertCloudGUIDsToCloudPath(String region, Guid projectGuid, Guid modelGuid) [02/09/2025 14:20:40] at NebulaDA.Revit.DB.ExternalDBApplication.DesignAutomationReadyEvent(Object sender, DesignAutomationReadyEventArgs e)

Despite spending a lot of time on this, I still don't know what may be going wrong 😞
Could anybody please help me out with the solution, thoughts, ideas?

Thanks!

Hello,

I was testing that adsk3LeggedToken, some weeks ago and was able to make work with no problem.

You could check if the user changed and the login userid is available.

Console.WriteLine($"Username: \t{application.Username}"); Console.WriteLine($"LoginUserId: \t{application.LoginUserId}");

I suppose the 'You must sign in to Autodesk 360 in order to complete this action.' only happens when the user is not login.

Here some references:

Seemingly during the execution of the activity there is no user logged on ! 😞

[02/10/2025 12:16:53] ===> Username: acesuser
[02/10/2025 12:16:54] ===> LoginUserId:

My Workitem thou DOES Include the 3Legged access token

Request Body { "activityId": "NVCloudManagerDA.NVCMActivity2024+test2024", "arguments": { "NVCMParams" : { "url": "data&colon;application/json, [{'Region': 'US', 'ProjectId': '062b8c8b-d33b-473f-9760-xxx', 'ModelGuid': 'c20b5561-4f6b-4eb1-b9b7-xxx'}]", }, "result": { "url": "urn:adsk.objects:os.object:nv_cm_bucket/nv_cm_output", "verb": "put", "headers": { "Authorization": "Bearer eyJhbGciOiJSUzI1NiIsImtpZCI6IlhrU............7CFT7KL2A" } } }, "adsk3LeggedToken" : "eyJhbGciOiJSUzI1NiIsImtpZC......7kg" }

Any Ideas about why is my user not logged in?

Appreciate your help.

The only thing I'm doing different is that I'm using the Design Automation c# sdk and the only way I found to enable the adsk3LeggedToken was using a StringArgument and that result in something like this:

{ "activityId": "ricaun.RevitAddin_DA_Tester2022Activity+dev", "arguments": { "input": { "url": "/Masked:url", "verb": "get" }, "output": { "url": "https://cdn.us.oss.api.autodesk.com/Masked:url", "verb": "put" }, "adsk3LeggedToken": { "value": "Masked:token" } } }

I suppose both ways should work, I didn't test the way you are doing like in the blog reference.

Duh! I've found it! Such a silly mistake!

My adsk3LeggedToken was OUTSIDE of the "arguments" scope when submitting the new WorkItem request!

Thanks for your help!
