CAD (computer-aided design) - is the use of computer systems that enables a designer to design and view anything in real time, online and with accuracy, it has become an important tool for viewing and drafting. With the use of CAD it has become easy, especially for architects and engineers to design any imaginary drawing model of a building or infrastructure and to predict structural problems and find solutions even before they arise. Traditionally, pen and scale were used for drafting only a 2d image of an object, but with CAD, a 3d image of any object can be drawn especially if you have such tool as free online cad viewer for this. The big advantage of using CAD compared to traditional methods for designing is that it gives flexibility to manipulate and change the design in a fraction of the time. Online CAD software offers different features depending on which design process you're working on. There are specific features for 2d vector based graphics and 3d modeling of solid surfaces.

You can download the Nuget package or view the sample code at the Demo link in the github repository.
