What are the disadvantages of solid modeling over 2D CAD work?
The disadvantages of solid modeling over conventional 2D CAD design are: the requirement for faster and more powerful hardware to run the solid modeling software; increased cost of the hardware, and software; getting up the learning curve of the solid modeling software; and learning to think differently about the design process. Just as you had to when converting from manual design and drafting on a drawing board to 2D CAD, the thought processes change when going from 3D wireframe design to 3D solid modeling. Also the process of porting your 3D solid model to 3D FEA and getting it to mesh properly isn’t always as easy as advertised and can be a problem.
