Alibre Design:
Alibre Design is a parametric feature-based three-dimensional Solid modeling CAD software created by Alibre, Inc.
Overview:
Alibre Design is a mechanical engineering and design CAD tool capable of creating complex 3D models, assemblies, and 2D drawings. Alibre Design is a parametric, feature-based modeler allowing users to create intelligent 3D design using parameters for dimensions that can be varied at any time, and common engineering features such as holes, chamfers and fillets. Features also incorporate parameters, such as the diameter or radius of a hole, in addition to other inherent attributes such as whether a hole is countersunk or counterbored. Another common property of a hole, or a "cut," which is a feature of arbitrary shape that removes material, is its depth. For instance, a hole or cut can be a "through all" causing it to always pass completely though a part no matter what its thickness.
