About[ edit ] Founded inAlibre began working closely with Microsoft in to develop the first web-based collaborative 3D design environment. Following this development, Alibre received a patent for "System and method for solid modeling," protecting their technologies for generating 3D geometries across a high bandwidth, distributed network. Parametric solid modeling is driven by intelligent dimensions, meaning that the software automatically recomputes designs to accommodate changes to a single dimension, thereby maintaining the design's dimensional accuracy without necessitating manual adjustment of each dimension. Alibre Design Professional has a basic set of features intended for users to get started with CAD, whereas Alibre Design Expert is a 3D and 2D modeling application suitable or intended for professional use. Some of Alibre's key design tools include: Part modeling to define the geometry of individual components Sheet metal modeling to define the geometry of individual components created from sheeted materials, such as sheet metal. Software adheres to the real-world constraints of sheeted goods Assembly modeling to define relationships between individual components for final assembled designs. Free training is also available via online tutorials and videos.
