What is Computer Aided Design (CAD) Software?
Computer Aided Design (CAD) software is a tool that enables engineers, scientists, and designers to create detailed and precise models and drawings of physical components. In the context of
nanotechnology, CAD tools are invaluable for designing and simulating the behavior of nanoscale structures and devices.
Why is CAD Important in Nanotechnology?
Nanotechnology operates at the
nanoscale, where traditional design and fabrication methods become impractical. CAD software allows researchers to visualize, model, and predict the properties and behaviors of nanoscale materials and devices before they are physically fabricated. This reduces the time and cost of development and helps in understanding complex nanoscale phenomena.
