This tool provided made it affordable for smaller design, engineering, and architecture companies to create detailed technical drawings. Autodesk became a public company in John Walker did not enjoy the process of writing the prospectus, relating the process to "lying on the beach or juggling chainsaws". In , Timothy Vernor sued Autodesk Vernor v. Autodesk, Inc. He had obtained the software from an Autodesk licensee at an office liquidation sale. In February and March , both sides filed motions for summary judgment addressing the issue whether the First Sale Doctrine applies to previously licensed software.
As such, Autodesk could not pursue an action for copyright infringement against Vernor, who sought to resell used versions of its software on eBay. Autodesk appealed the decision to the United States Court of Appeals for the Ninth Circuit , which reversed the lower court ruling, denying Vernor the right to resale Autodesk software due to Autodesk's nontransferable licensing restrictions.
Supreme Court let stand the 9th Circuit Court of Appeals ruling. This is in addition to the almost 1, job cuts announced in January The number of Autodesk employees has shrunk from approximately 9, to 7, in less than 2 years. The asset were used to strengthen Autodesk's position in the utility industry. On February 21, , Autodesk acquired Revit Technology Corporation, a developer of parametric building technology for building design, construction, and management.
On August 6, , Autodesk acquired CAiCE Software Corporation, a developer of surveying and engineering applications for transportation agencies and consultants.
On May 1, , Autodesk announced agreed to acquire Moldflow Corporation , a leading provider of injection molding simulation software. On June 26, , a press release announced the acquisition of Square One Research and its flagship product, Ecotect.
On August 27, , Autodesk signs agreement to acquire SeeControl. Common applications for environmental sustainable design include mechanical ventilation, external flow wind loading , natural ventilation, and occupant comfort. Other energy applications include analysis for building energy, solar load, advanced energy and heating and cooling.

If you're asking strictly about the average, you can find the data necessary to determine that number in Caltech's Common Data Set.
Autodesk is discontinuing Ecotect Analysis. This document provides common questions and answers about this transition. Why is Autodesk discontinuing Ecotect Analysis? One element of this evolution has been to integrate functionality similar to Ecotect Analysis into the Revit product family.
This work is now at a point where, effective March 20, , licenses to Autodesk Ecotect Analysis will no longer be available for purchase. This change will allow Autodesk to shift resources, maximizing development efforts on BIM and cloud-based solutions for building performance analysis and visualization.
When will Ecotect Analysis be discontinued? After March 20, , additional licenses will not be available. You may add Subscription to existing Ecotect licenses until that time. Will my license for Ecotect Analysis remain valid? Yes, if you hold a perpetual license for Ecotect Analysis, you may continue to use the software in accordance to your licensing agreement. As an existing customer, will I be able to purchase additional licenses for Ecotect Analysis ? Can I renew my Ecotect Analysis subscription?
Yes, you can renew your subscription, and you will continue to receive subscription benefits. What alternative solutions does Autodesk offer for key Ecotect Analysis features? Key Ecotect solutions are now available in the Revit environment. Here is a list of the most widely performed Ecotect tasks and how they can now be addressed with Revit: Solar Analysis: Revit now includes a solar analysis plug-in that incorporates a more advanced algorithm than the one used by Ecotect.
With this new plug-in, analysis is fully integrated with Revit. You can visualize and quantify the distribution of solar radiation for any date and time and directly display the results on your model. Sun and Shadow Studies: The interactive sun path tool within Revit allows the sun path to be visualized to study the impact of natural light and shadows on the exteriors and interiors of the project for any location.
This tool is fully integrated with Revit and can be used to create solar studies for any moment in time, in addition to any specified time range. Daylighting and Lighting: Revit can now perform daylighting and electric lighting analysis using Lighting Analysis for Revit.
The analysis uses the fast cloud service of Autodesk Rendering to expose electric and solar lighting results directly on the Revit model. Lighting Analysis for Revit allows you to input your location, time, as well as your preferred sky model, and the results have been validated against Radiance.
Thermal performance: You can calculate the thermal loads for you project, taking into account internal loads, solar stress, and the effect of the building envelope. You can then calculate heating and cooling loads for models and analyze the effects of occupancy, internal gains, infiltration, and equipment.
Whole building energy analysis: The integrated Energy Analysis for Revit has been enhanced in Revit and beyond to support more detailed building elements. The improved workflow creates an energy analytical model directly from a Revit model, and returns results within Revit.
Analysis is performed using Green Building Studio, and allows you to calculate total energy use and cost on an annual, monthly, daily, and hourly basis, using a global database of weather information. You also have the ability to customize the visual representation of the data reported back to you through Green Building Studio. Weather data visualization: This functionality has been available in Revit since and more recently FormIt. The weather data that is represented in these tools comes from the Autodesk Climate Server, which contains over a million virtual weather stations that are based on sound meteorological science and research.
