Set DataStorage Entity from external application

Hi,

Exploring options to create DataStorage and set entity in Revit document from external application. After setting DataStorage entity need to save document. This need to be done running Revit instance in background.

Currently could create storage and update entity in Add-In. But this need executed from separate exe.

The question is, How to start Revit instance from exe and access Revit API to update document storage entity.

You can start Revit from an external EXE using Process.Start:

All of these steps require a valid Revit API context. One way to obtain that is to use an external event:

Hi @prakash.muthu

I have a workaround for your task, Kindly check the below points.

Implement your Extensible storage helper methods in a static class.
Design a simple standalone application (exe) that starts Revit in a separate process.

static void Main(string[] args) { string exeLocation = @"C:\Program Files\Autodesk\Revit 2023\Revit.exe"; string arguments = @"/languageENG /runhidden /nosplash"; ProcessStartInfo revitInfo= new ProcessStartInfo(exeLocation,arguments); Process.Start(revitInfo); }

In the OnStartup method your application implements, subscribe to ApplicationInitialized event.
When your add-in receives the event, open the document you want to add data storage by calling the helper methods.
When the document is opened, perform the process; output whatever you need to output.
Save and Close the document.
Exit the ApplicationInitialized event handler
When the standalone application receives the inter-process message from your add-in, kill the Revit process.

Hope this will Helps 🙂
