Free software extensions to proprietary software

Although the following software packages are legally free software by thesmelves, they are practically only capable of operating in conjunction with proprietary software. In the software industry, culturally this type of software would usually not be considered free software due to their dependency on proprietary software. However, we are happy to document them here to help demonstrate the impact and reach of open source.

See more about the type of free software that OSArch supports.

	BCFier	See also Revit extensions. Create and open BIM Collaboration Format (BCF) files directly within Autodesk Revit. With BCFier you can create issues of 3D and 2D* views, add multiple views and comments to an issue and easily share them with other team members. BCFier also features a standalone Windows app that lets you review BCF files without the need of third party tools.	GPL-3.0
	Dynamo	See also Revit extensions. Dynamo extends building information modeling with the data and logic environment of a graphical algorithm editor. Dynamo is an open source tool, built on a community that contributes to making it better.	Apache-2.0
	Grevit	See also Revit extensions. "Build your BIM Model directly in Grasshopper. Grevit allows you to define BIM Elements in Grasshopper or SketchUp and translate them directly to Autodesk Revit or AutoCad Architecture. Grevit follows a one way process so your design model remains the geometrical source of truth: send geometry and attributes from Rhino/Grassopper or SketchUp to Autodesk Revit or ACA."	MIT
