  What operations are exactly meant by 3D visualization? First, you can examine the design plan with your customer or with other design team members, to share design target image. It is always important to share such physical images in making physical things.
  Second, you can measure 3D distances, at arbitrary positions, for example between bondwires of two chips. Third, 2 or more chips can be placed and arranged in various way. Fourth, you can add other objects such as heatsink, or cell phone plastic case, etc, to intuitively understanding if parts are organized well. (For numerical analysis, however. you may need more specialized tools.) There would be more interesting usages you can invent. The expected merits of 3D visualization can be summarized as follows.
