Main Parts of The Work

  1. Migrate the existing Revit WindowWizard Plugin to be used within AppBundle of Design Automation for Revit. Please check PlugIn

  2. Create your App, upload the AppBundle, define your Activity and test the workitem with the Postman collection under Postman Collection

  3. Create the Web App to call the workitem.

Web App Setup

Prerequisites

  1. Forge Account: Learn how to create a Forge Account, activate subscription and create an app at this tutorial.
  2. Visual Code: Visual Code (Windows or MacOS)
  3. ngrok: Routing tool, download here
  4. Revit 2019: required to compile changes into the plugin
  5. Window family template: A family template that is required while creating window family, you can use this sample template
  6. JavaScript ES6 syntax for server-side
  7. JavaScript basic knowledge with jQuery

For using this sample, you need an Autodesk developer credentials. Visit the Forge Developer Portal, sign up for an account, then create an app. For this new app, use http://localhost:3000/api/forge/callback/oauth as Callback URL, although is not used on 2-legged flow. Finally take note of the Client ID and Client Secret.

To run it, install the required packages, set the enviroment variables with your client ID & secret and finally start it. Via command line, navigate to the folder where this repository was cloned and use the following:

Mac OSX/Linux (Terminal)

npm install
export FORGE_CLIENT_ID=<<YOUR CLIENT ID FROM DEVELOPER PORTAL>>
export FORGE_CLIENT_SECRET=<<YOUR CLIENT SECRET>>
export FORGE_CALLBACK_URL=<<YOUR CALLBACK URL>>
export FORGE_WEBHOOK_URL=<<YOUR DESIGN AUTOMATION FOR REVIT CALLBACK URL>>
export REVIT_IO_NICK_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT NICK NAME>>
export REVIT_IO_APP_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT APP NAME>>
export REVIT_IO_ACTIVITY_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT ACTIVITY NAME>>
npm start

Windows (use Node.js command line from Start menu)

npm install
set FORGE_CLIENT_ID=<<YOUR CLIENT ID FROM DEVELOPER PORTAL>>
set FORGE_CLIENT_SECRET=<<YOUR CLIENT SECRET>>
set FORGE_CALLBACK_URL=<<YOUR CALLBACK URL>>
set FORGE_WEBHOOK_URL=<<YOUR DESIGN AUTOMATION FOR REVIT CALLBACK URL>>
set REVIT_IO_NICK_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT NICK NAME>>
set REVIT_IO_APP_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT APP NAME>>
set REVIT_IO_ACTIVITY_NAME=<<YOUR DESIGN AUTOMATION FOR REVIT ACTIVITY NAME>>
npm start

ngrok

Run ngrok http 3000 to create a tunnel to your local machine, then copy the address into the FORGE_WEBHOOK_URL environment variable. Please check WebHooks for details.

Start the app
