How to post new version file BIM 360 cloud model using Design Automation?

Question

I have a problem when I'm try to update new parameter override to BIM 360 cloud Revit model and post a new publish version for Revit model,

Example: The latest version model in BIM 360 with file name sample.rvt is version 1 . After set parameter will be become the file name sample.rvt with version 2.

These are the steps I'm tried to achieve :

• Create bundle app update parameters

  private void DoJob(DesignAutomationData data)
  {
      if(data.RevitDoc == null) throw new Exception("Have problem with DesignAutomationData.RevitDoc");
      Document doc = data.RevitDoc;
      List<InputParams> inputParams = GetParamsJson();
      string result = SetParameterCommand.Execute(doc, inputParams);
      File.WriteAllText("result.txt", result);
  }
  

• Create activity

  Activity activitySpec = new Activity()
  {
     // Activities 
     ... 
  }
  

• Execute work item

  private async Task<Status> ExecuteWorkItem(string forgeToken,List<InputParams> inputParams, string projectId, string versionId, string callBackUrl)
      ...
  

• Post new version - I don't know how to implement this

I failed with the last step, post new version, because I can't find any sample on GitHub for post new version from BIM360 Model just saved as file to bucket. If you have any C# code sample, I'd appreciate it if you shared it.

Answer 1

Finally I also have answer for my problem at this document: https://aps.autodesk.com/en/docs/bim360/v1/tutorials/document-management/upload-document-s3/

This is step by step I resolved my problem :

1. Create a new storage object

2. Check file item exist and use this item if it exit.

  var items = await GetFolderItems(projectId, folderUrn, accessToken).ConfigureAwait(false);
        var item = items.Cast<KeyValuePair<string, dynamic>>().FirstOrDefault(item =>
            item.Value.attributes.displayName.Equals(filename, StringComparison.OrdinalIgnoreCase));

3. Post a update version :

• In case item not exitss, we create a new one .
• In case item exites, keep use item id at previous version like urn:adsk.wipprod:dm.lineage:J-CiZHzFTGy-A0-RfhEUMQ:

 private static async Task<string> UpdateVersionAsync(string projectId, string itemId, string objectId,
        string filename, string accessToken)
    {
        var versionsApi = new VersionsApi();
        versionsApi.Configuration.AccessToken = accessToken;

        var relationships = new CreateVersionDataRelationships
        (
            new CreateVersionDataRelationshipsItem
            (
                new CreateVersionDataRelationshipsItemData
                (
                    CreateVersionDataRelationshipsItemData.TypeEnum.Items,
                    itemId
                )
            ),
            new CreateItemRelationshipsStorage
            (
                new CreateItemRelationshipsStorageData
                (
                    CreateItemRelationshipsStorageData.TypeEnum.Objects,
                    objectId
                )
            )
        );
        var createVersion = new CreateVersion
        (
            new JsonApiVersionJsonapi
            (
                JsonApiVersionJsonapi.VersionEnum._0
            ),
            new CreateVersionData
            (
                CreateVersionData.TypeEnum.Versions,
                new CreateStorageDataAttributes
                (
                    filename,
                    new BaseAttributesExtensionObject
                    (
                        "versions:autodesk.bim360:File",
                        "1.0",
                        new JsonApiLink(string.Empty),
                        null
                    )
                ),
                relationships
            )
        );

        dynamic versionResponse = await versionsApi.PostVersionAsync(projectId, createVersion).ConfigureAwait(false);
        var versionId = versionResponse.data.id;
        return versionId;
    }
