3D CAD Modeling and 3D CAD Design enhances the design characteristics in many ways while providing several benefits. Design efficiencies are improved where traditional 2D drawing representations can be easily achieved from a completed 3D design versus manually drawing each 2D representation in CAD. Being able to view equipment, components, and systems in three dimensional space allows almost endless possibilities towards planning, implementation, construction, and manufacturing efforts, which is extremely important in the electric power industry. 3D CAD Design and Modeling is improving and aiding with power substation designs compared with 2D designs ….
