How to create multiple files in design automation api for revit and download result as one zip file

Question

I am working on a project where I am required to create multiple revit files, zip them all together and download the zip file as the output in design automation API for Revit.

My project is completely working as expected on my local machine, but when I upload my appbundle and execute my workitem, I get a "failedInstructions" status.

I am not aware whether it is possible to create multiple revit files in design automation API

Following is what I have tried:

This is my workitem json, you see I am passing a json array with sample data for the wall.

 "arguments":{
        "ElementParams":{
            "url":"{'elementdata':[[{'Keys':'Sytème','Value':'Wall_1'},{'Keys':'Thickness','Value':'120.00'},{'Keys':'Length','Value':'2500.00'},{'Keys':'Height','Value':'1200.00'}],[{'Keys':'Sytème','Value':'Wall_2'},{'Keys':'Thickness','Value':'120.00'},{'Keys':'Length','Value':'2500.00'},{'Keys':'Height','Value':'1200.00'}],[{'Keys':'Sytème','Value':'Wall_3'},{'Keys':'Thickness','Value':'120.00'},{'Keys':'Length','Value':'2500.00'},{'Keys':'Height','Value':'1200.00'}],[{'Keys':'Sytème','Value':'Wall_4'},{'Keys':'Thickness','Value':'120.00'},{'Keys':'Length','Value':'2500.00'},{'Keys':'Height','Value':'1200.00'}]]}"
            },

        "resultFamily":{
            "verb":"put",
            "url":"https://storage.googleapis.com/bucketname/RevitObjects.zip?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
            "headers": {
              "Authorization": "",
              "Content-Type": "application/octet-stream"
            }
        }
    }

In my code, I create a new document in a loop.

Document doc = app.NewProjectDocument(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + "\\" + "DefaultTemplates.rte");

and save and close the current document

SaveAsOptions options = new SaveAsOptions();
options.OverwriteExistingFile = true;
doc.SaveAs(Assembly.GetExecutingAssembly().Location) + "\\" + fileName, options);

doc.Close(); //Closing the document

List<string> files = Directory.GetFiles(Assembly.GetExecutingAssembly().Location) + "\\").Where(a => a.Contains(Path.GetFileNameWithoutExtension(fileName)) && a.Split('.').Count() > 2).ToList();
foreach (var fl in files)
{
if (File.Exists(fl))
File.Delete(fl);
}

byte[] filebytes = File.ReadAllBytes(GlobalData.TemplatePath + "\\" + GlobalData.DestinationFile);
GlobalData.FileList.Add(GlobalData.DestinationFile, filebytes);

Here fileName is Wall_1, Wall_2, Wall_3 and Wall_4 which will appear in a loop
Here what I am doing is saving the created revit file example Wall_1
After closing the document, there is a copy of the file created example Wall_1.0001.rvt. I delete all the additional files created and keep one final version and add it to file bytes.

The data added in byte[] filebytes is then used to create a zip file of name "RevitObjects.zip"
After which I delete all the files.

This process works perfect on my local machine, but when I execute the workitem the log created states the following:

[07/03/2019 13:47:38] Error: An unexpected error happened during phase CoreEngineExecution of job.
[07/03/2019 13:47:38] Job finished with result FailedExecution
[07/03/2019 13:47:38] Job Status:
{
  "status": "failedInstructions",

No other error message is stated in the log.

Let me know if multiple revit document creation is possible in design automation api for revit
Are we not allowed to perform delete operation in the working directory.
I tried by creating a folder and performing the same operation mentioned above, but I got an access denied message.
Let me know where I have gone wrong. Also any guidance to achieve the task will be appreciated
Thank you

Answer 1

First of all, Yes, multiple revit file output is supported by Design Automation system, it's very easy that you just need to set the parameter zip to "true" of your output, and within your plugin, save all your output file to a folder as you named in your output parameter of "localName", please check my blog post at https://forge.autodesk.com/blog/how-generate-dynamic-number-output-design-automation-revit-v3 for all the details.

You are not allowed to access any other folders except the current working folder, you can create subfolder under current working folder and put all your files there.

Hope it helps.

如果json参数很大，则可以提供“ inputParameters.json”作为输入文件，而不是在WorkItem有效负载中传递所有内容
