Autodesk Revit Add-on / Plugin

Onuma, Inc. is looking for bids for a Revit Add-on/Plugin (.Net) to exchange building model information (spatial data and attribute data) between Autodesk Revit 2009 and our own BIM application through our own XML format. Only the following elements/model object have to be converted during export and import: - Floor Slabs (spatial attriubtes like placment, rotation, thickness, shape) - Room shapes (placement, shapes, with some attributes like name, number, etc.) - Furniture (names, placement, overall dimensions, few attributes, no complex geometries). During import into Revit, the Add-on needs to create instances from the furniture families in Revit mapped to the name of the equpiment that is being imported. - no slanted or clipped shapes at this time. A future development will include more elements such as walls, roofs, etc but this is not part of this project. We will require a non-disclosure agreement with the developers. The source code will be property of Onuma, Inc. and has to be delivered after completion together with the finalized Add-on.
