Professional 3D Modeling CAD Software Compatible with Windows XP and higher including Windows 10.1 & Mac OSX This is a Constructive Solid Geometry-based 3D modeling software that puts a special emphasis on accuracy. While a non-intimidating user interface makes it accessible to all types of users, its advanced geometric configuration allows for modeling through the use of specific coordinates, offering the highest level of precision. For more than 20 years, it has been the primary tri-service solid modeling CAD system used by the U.S. military to model weapons systems for vulnerability and lethality analyses. The solid modeling system is frequently used in a wide range of military, academic, and industrial applications including in the design and analysis of vehicles, mechanical parts, and architecture. The package has also been used in radiation dose planning, medical visualization, computer graphics education, CSG concepts and modeling education, and system performance benchmark testing among other purposes. Specific modeling features include a large library of geometric representations that offer both traditional and complex shapes in addition to the ability to combine shapes into a single object. The realistic quality of objects are enhanced by signal processing tools and path-tracing photon mapping support. Outside of accuracy, ease of use and lightning-fast speeds are both features of that make it popular among its users. A simple-to-use interface eases the learning curve and offers even the most novice users impressive final results. Its ability to perform on multiple platforms and its availability in source or binary code form makes it easy to use on more than one computer. It has been in development for over 30 years. This modeling software is offered as a package that includes over 400 tools, utilities, and applications in addition to a network of support.
