C# Plugin for Revit to export geometry in custom format

We need a plugin to export geometry (mesh + uv) in our custom format. We will provide a dll that will be used to save data in our format. So it is enough to grab mesh information from Revit and pass to our library as: layer name, list of vertices, list of triangles, uv (if they are). The most important thing, is to group Revit object by material. So all meshes that have the same material assigned, go to one layer. Interface details: - add "Felix o3d" to Export Menu - add 2 buttons "Export to Felix" and "Export to Felix Object Library" (from technical point of view, it is the same export but it saves in predefined path. In that way Felix imports the file automatically) - a lite config. User has to show where the Felix has been installed (if it was not installed in default path) To help development, we will provide a code of the same plugin written for Rhino. When the project is done, we want to get complied plugin + source code. You can dowload Felix from: [login to view URL] And the Rhino plugin: [login to view URL]
