What is the function of the ORTHO mode in AutoCAD?

• Restricts movement to horizontal and vertical directions

• Allows freehand drawing

• Snaps to predefined points

• Creates parallel lines automatically

What are the primary benefits of using CAD tools?

• Increased material costs

• The primary benefits of using CAD tools include increased design accuracy, improved productivity, enhanced collaboration, and the ability to easily modify and simulate designs.

• Limited design options

What is the difference between 2D and 3D CAD?

• 2D CAD can represent objects in three dimensions.

• 3D CAD is only used for animations, while 2D CAD is for drawings.

• 2D CAD is flat and lacks depth, whereas 3D CAD includes depth and allows for more realistic modeling.

• 2D CAD is more advanced than 3D CAD.
