3D printing

What is the difference between a 2D drawing and  3D drawing?

• The main difference is that 2D drawings are flat and lack depth, whereas 3D drawings provide a sense of volume and perspective.
• 2D drawings can show depth, while 3D drawings cannot.
• 3D drawings are always created using software, while 2D drawings are hand-drawn.
• 2D drawings are more detailed than 3D drawings.
