Single Unified User Interface SAP2000 offers a single unified user interface for modeling, analysis and design. Autocad-like snap tools for fast and easy model creation Zoom controls Standard views XY, XZ, YZ, 3D Live multiple graphical windows that make for easy navigation of complex models Active planar view is automatically highlighted in the 3D view window Developed elevation option to define custom views, including "unwrapping" cylindrical and irregular geometry Define working planes for creating and editing complex geometries Coordinate Systems/Grids Cartesian Cylindrical Generalized Grid Sytems - allows for a system comprised of arbitrarily defined grid lines. Models can have multiple coordinate systems/grids which can be rotated in any direction.
