@chuongmep are you trying to use a Graph in Dynamo Player, or trying to use the Player API to create your own addin?

[chuongmep]

Hi @Amoursol , I saw it can call from forma to open user interface of dynamo player, so I just want to know how it posible to use the Player API to create my own addin and execute dynamo script, and then I can connect to forma platform.

Ah, understood! @saintentropy @twastvedt any insight you can provide to @chuongmep here?

[twastvedt]

Hi @chuongmep! Are you building an addin in Revit, Dynamo, or Forma? Is the goal to run a Dynamo graph in the Revit context from Forma?

[chuongmep]

Hi @twastvedt , that is Revit add-in can intergrate with Dynamo, my process is intergrate from :

• Revit Add-in. -> Dynamo
• Revit Add-in -> Forma
  Can we call open dynamo player from Revit Add-in ?

OK! Some thoughts:
You can do a lot with pyRevit, including starting Dynamo and running a graph. Here's some discussion on that topic:

Relay allows you to add a button to the Revit ribbon that runs a Dynamo graph. Maybe that's what you need, or it's open source and you might be able to learn from what it does.

Orkestra has capability around sharing Dynamo scripts, if that's the end goal

Thank you @twastvedt , I think I'm done with first step to open dynamo player now :

 RevitCommandId commandId = RevitCommandId.LookupPostableCommandId(PostableCommand.DynamoPlayer);
                       commandData.Application.PostCommand(commandId);

Nexte step with me is how to add default path setting for folder in Dynamo Player ?

[twastvedt]

Hi @chuongmep , sorry for the delay. What version of Revit and Dynamo are you using? Up to Revit 2023, that setting is in %appdata%\generative-design-client-2022\AppSettings.json. Starting in Revit 2024 the default folder is set in Dynamo's settings file, at %appdata%\Dynamo\Dynamo Revit\<Dynamo version>\DynamoSettings.xml.
