Onshape is a CAD software system, delivered via internet. It is focused on mechanical CAD and is used for product and machinery design in many industries, such as electronics, machinery, medical devices, 3D printing, machine parts and industrial equipment.

It makes use of cloud computing, with computer-intensive processing and rendering performed on Internet-based servers. Users are able to interact with the system via a web browser or the iOS and Android apps.

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.
