今天在CSI公司的官方网站上看到了SAP2000的V11版本已经出炉了。实在是太快了，这么快就更新了。
现在把SAP2000的V11版本增强说明贴出来。
里面提到了V11版本在设计，分析等各个方面做了改进。
SAP2000 – V11 – Enhancements List

Computers and Structures, Inc.’s significantly enhanced SAP2000 V11 is now shipping. Advancements have been made to almost every aspect of the program, including new graphics and new solvers. This fully integrated application for the modeling, analysis, and design of structures continues to be available in three levels: Basic, Plus and Advanced. The new and innovative features of Version 11 are listed below. Please contact sales@csiberkeley.com for more information.

Graphical User Interface (GUI)

· OpenGL graphics added to main model window for fast drawing and display
· Drawing significantly improved with several intelligent snaps and constraints
· On-the-fly working plane added for modeling at arbitrary orientations
· Numerous new selection methods added, including parallel to object, polygon fence and
poly-line intersection, and by supports and constraints
· "Fly" through models using user-defined paths
· Selection by any combination of input or output values using database tables
· Right-button information forms now allow easy editing of all items
· Forms requiring previously defined items now allow adding/editing of those items
