How can I create an activity for data conversion in Design Automation API?

Question

I\'m prototyping a web service to convert data using Design Automation API in Autodesk Forge.

My approach is to invoke an activity that executes a script to import a tar

You can use the Activity “Translate-STEP2DWG". It takes a .stp file as input and generate result.dwg as output. This is a public activity that anybody can send workitems against to it.

The activity is defined like this:

{
      "Id": "Translate-STEP2DWG",
      "AppPackages": [],
      "HostApplication": "AcTranslators.exe",
      "RequiredEngineVersion": "22.0",
      "Parameters": {
        "InputParameters": [
          {
            "Name": "HostDwg",
            "LocalFileName": "source.stp"
          }
        ],
        "OutputParameters": [
          {
            "Name": "Result",
            "LocalFileName": "result.dwg"
          }
        ]
      },
      "Instruction": {
        "CommandLineParameters": "-i source.stp -o result.dwg",
        "Script": ""
      },
      "AllowedChildProcesses": [
      ],
      "IsPublic": true,
      "Version": 1,
      "Description": ""
    }

Here is a sample workitem request body:

{
  "ActivityId": "Translate-STEP2DWG",
  "Arguments": {
    "InputArguments": [
      {
        "Resource": "https://s3.amazonaws.com/AutoCAD-Core-Engine-Services/TestDwg/3DStep.stp",
        "Name": "HostDwg"
      }
    ],
    "OutputArguments": [
      {
        "Name": "Result",
        "HttpVerb": "POST"
      }
    ]
  }
}
