RS Mech Visuals is a design program that enables its users to create 2D sectional views of solid-fueled rocket engines in real time. Program allows users to make use of predefined mechanical rule sets and components as well as creating new ones. These designs are created for performance evaluations of the engines. Currently this process requires more resource heavy 3D CAD programs which takes a longer period of time and requires more man power. RS Mech Visuals will make it much easier to handle issue. Although program is created for rocket engine design the underlying infrastructure can be used for any sort of design project that includes multiple sub components.
