Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates. It is used in industries including architecture, industrial and product design, in multimedia and graphic design and runs on Microsoft Windows and OS X. Rhino uses Grasshopper, a visual scripting language add-on, developed by Robert McNeel & Associates.

Rhino is based on the NURBS mathematical model, so it focuses on producing precise representations of curves and freedom surfaces. It allows users to create, edit, analyse, and visualize NURBS curves, surfaces, solid bodies, point clouds and polymeshes.

T-FLEX is a Parasolid-based parametric CAD software application for 3D solid modeling and 2D design and drafting, made by Russian software company Top Systems. T-FLEX CAD is developed for Microsoft Windows XP, Vista and is localized into many languages.

T-FLEX CAD is a design solution which was created for mechanical engineering. It provides drafting, modeling and assembly tools that allow engineers to develop various products, from single parts to assemblies.

T-FLEX CAD supports a wide range of operations: drawings, assembly drawings, solids, surfaces, parts, parts with multiple solid bodies, assembly models, sheet metal, bill of materials, etc.

T-FLEX CAD provides parametric, adaptive and associative technology aimed at family-of-parts manufacturers or other design situations that use similar geometry but require many different sizes or permutations. Besides parametric 3D modeling T-FLEX CAD supports parametric 2D drawings creation from scratch. Parametric 2D assemblies can be created as well by inserting parametric 2D components.
