RvtVa3c

A Revit custom exporter add-in generating JSON output for the vA3C three.js AEC viewer.

Setup, Compilation and Installation

RvtVa3c is a standard Revit add-in application.

It is installed in the standard manner, i.e., by copying two files to the standard Revit Add-Ins folder:

• The .NET assembly DLL RvtVa3c.dll
• The add-in manifest RvtVa3c.addin

In order to generate the DLL, you download and compile the Visual Studio solution:

• Download or clone the RvtVa3c GitHub repository.
• Open the solution file RvtVa3c.sln in Visual Studio 2012 or later.
• Build the solution locally:

  • Add references to the Revit API assembly files RevitAPI.dll and RevitAPIUI.dll, located in your Revit installation directory, e.g.,

      C:\Program Files\Autodesk\Revit Architecture 2015
    

  • If you wish to debug, set up the path to the Revit executable in the Debug tab, Start External Program; change the path to your system installation, e.g.,�

      C:\Program Files\Autodesk\Revit Architecture 2015\Revit.exe
    

  • Build the solution.

This will open the Revit installation you referred to, and install the plugin, which can then be launched from the Revit Add-Ins tab.

And wonderfully exports the your Revit model to a JSON file.

For more details, please refer to the Revit API Getting Started material, especially the DevTV and My First Revit Plugin tutorials.
