Project Vasari is our free technology preview of an easy-to-use, expressive design tool for creating building concepts with integrated cloud-based analysis for energy and carbon. The file used by Project Vasari are compatible with Autodesk Revit, so the work done with Project Vasari can be integrated in Building Information Models.
The existing 2.1 technology preview ends on March 31, 2012. This 2.5 update will operate until August 31, 2012.
In addition to the time extension, the Wiki help page notes that the updated technology preview includes new capabilities:
Working in Perspective 3D Views
Now you can create and edit conceptual models in Perspective 3D views instead of just Orthographic. Perspective view is now the default view.
Extrude Face Tool
There is a new in-canvas control to extrude mass faces with or without edges for improved form manipulation.
Solar Radiation Automatic Updates
Now you can enable the Ecotect Solar Radiation feature to automatically update exported .csv files when analysis results are updated. This functionality has graduated from the Autodesk Labs Featured Add-ins section and is now integrated in Project Vasari.
Improved Automatic Zoning for Energy Models
Additional enhancements have been made to automatic zoning to support courtyards, circular forms, and forms with more complex perimeters.
Previous Featured Add-ins work with New 2.5
Project Vasari works-in-progress functionality can be used with Project Vasari 2.5. This includes Parametric Sliders, Parameters from Image, and Dynamo for Vasari.
Improved online services interaction
Tools that require Autodesk Cloud services like location and weather data now require sign in so that proper data for simulations is guaranteed.
In addition to Project Vasari Wikihelp updates, you can also access the Project Vasari Talk Design and Analysis Webinar video recordings.
Here's a video that provides an overview:
Conceptual design with cloud-based analysis remains alive in the lab.
