rvt | Remote Terminal for the Browser | Command Line Interface library

I tried to upload a zip file (containing .rvt base file and multiple .rvt link files) to OSS bucket following the steps from here. I received a 504 GATEWAY TIMEOUT status. My zip file size is close to 1GB, and upon searching, I understand that I should use resumable uploads for large files in chunks from here. Before I tried to chunk the data, I listed the details of my bucket using this API - https://developer.api.autodesk.com/oss/v2/buckets/bucketkey/objects/objectkey/details, and I see that my zip file is already uploaded without resumable API. I then took the objectId from the response of this API and further used it for Translation APIs after encoding. The generated URN is tested from Forge viewer and I could see my .rvt linked model as well.

I would like to know as why in the first place I received a timeout where there was no response objectId from the API call. Since the file is in-fact uploaded (as verified from listing the bucket), and I can use the URN out of it, will there be any hidden issues associated with this timeout. Please provide your valuable insights for the same. Also, it would be great if you can point me to the correct detailed out steps for uploading the larger zip files > 1GB.

Thank you.

I am integrating between Design automation and BIM 360 API in autodesk forge

1. I call step 7 Design automation https://forge.autodesk.com/en/docs/design-automation/v3/tutorials/revit/step7-post-workitem/

I'm developing a Revit plugin in C# for exporting data from Revit files. This plugin is used through the Design Automation API (i.e. without user interface, obviously). The whole process works fine for some RVT files. Unfortunately, for some other files, the document opening fails before any transaction has started, so I'm struggling to see how I can catch these opening errors (and possibly delete the corresponding failed elements), similarly to what is suggested in the official documentation inside transactions using IFailuresPreprocessor.

Does anyone have suggestion on how to handle errors during the document opening itself? Sorry if I miss something obvious. Thanks!

Part of the C# code is available here (basic code, like in the Design Automation tutorials), as well as the error logs.

When I get the download link for a Revit Model obtained in the cloud as shown here. I found that sometimes the link returns a Revit file and sometimes a zip file. I am passing this URL to Design Automation so it sometimes fails (in case the link downloads a zip file). How can I differentiate between the two items when in both cases item.data.attributes.displayName returns *.rvt. And what should be done to obtain rvt file in all cases?

This question discusses the same problem but there is no solution (it was 2 years old, hopefully something changed).

I have some Revit files stored in a BIM360 project. I am trying to visualize those files inside Forge Viewer. Now Forge Viewer won't work directly with Revit file/documents, but require the 'urn' of a translated file, in 'svf' format.

I could transform my Revit file into the 'svf' file using the Forge Model Derivative API, but that consume some credits, and I shouldn't be able to do this because when uploading a Revit file into BIM360, the translation is happening already there.

I was wondering then, how do I find out the 'urn' of the underlying 'svf' file for my Revit document ? I found few resources helping there, when browsing the content of my BIM360 folder, or checking the versions of my Revit document using Forge Data Management API, I should be able to access a derivative object in the response which represent the derived model that can be used by the Forge viewer. https://forums.autodesk.com/t5/bim-360-api-forum/connecting-forge-viewer-with-bim-360/td-p/6742779

However for me, there are no derivatives object in the API response, see below a sample of the API response (I have obfuscated some data for security purpose):

I have a problem with revit files loaded into BIM360; Rooms and spaces in Forge viewer are not displayed as in the example reported at the link https://forge.autodesk.com/blog/new-rvt-svf-model-derivative-parameter-generates-additional-content-including-rooms-and-spaces (see ); There is no volume, only one point. Otherwise, if I load revit model into a bucket, following the procedure above, rooms and spaces are represented as desired in the viewer forge (see ). Is there a possibility to call Data Management's APIs (as Model Derivative's APIs, https://forge.autodesk.com/en/docs/model-derivative/v2/reference/http/job-POST/) to load revit file in BIM360 folder by setting generateMasterViews parameter to true? Or is there the possibility in BIM360 to set this option by default for each revit file that is uploaded?

TIA Alder

I'm trying to translate a revit file directly from BIM360.
I posted a job like so:

In our solution we need a reference between a Revit model and its presence in the cloud (BIM 360/Autodesk Construction Cloud).

In Revit we open a cloud model or save a model to the cloud (Save As cloud model). The rvt-file obviously "knows" where it is placed in the cloud but I see no way to extract that information from the file. The challenge is therefore to find the files Item id in the cloud.

Currently we do the following:

From the Revit document we get

• CloudProjectName (extracted from Revit api Document.GetCloudModelPath())
• ModelGuid (Revit api Document.GetModelGUID())

Then...

1. Get the accounts for the user (Forge Datamanagement API https://developer.api.autodesk.com/project/v1/hubs)
2. For each account: Iterate through projects to find project with the specified name. (Forge Datamanagement API https://developer.api.autodesk.com/project/v1/hubs/:hub_id/projects)
3. If project found: Search root folder in project to find files with the specified ModelGuid (Forge Datamanagement API https://developer.api.autodesk.com/data/v1/projects/:project_id/folders/:folder_id/search?filter[attributes.extension.data.modelGuid]={ModelGuid})
4. If 1 or more files found: Pick out the 'original' file. (relationships.item.data.id == attributes.extension.data.originalItemUrn)

(We do not care about the cloud model version).

This actually works, except step 3 can be a bit tricky. It takes several minutes, maybe hours, from the model is uploaded to the cloud until a search is possible which is quite annoying.

So here is two questions:

1. Is there a better/easier way to find the cloud Item id of the file?
2. Is there an alternative to the 'search' call (step 3) or at least some kind of documentation saying when a result can be expected to be available?

I am trying to upgrade some parts of an old project, and ran across the issue of calling the webapi from the aspx.cs.

When i call the webapi from the htmlpage/angularjs, the request is authenticated and everything works fine.

When i try to call it from the aspx page, even though this.User is Authenticated(on the aspx page), when the call is recieved in the controller, the user is not set and therefor not authenticated.

• We are using owin cookie based authentication.
• On framework 4.7.

Is there any way to authenticate the webapi call, by include the RVT cookie or something?
