What limitation does a 2D cutter have regarding the types of objects it can work with?

A 2D cutter is specifically designed to create shapes and profiles from materials by cutting in two dimensions. This means it can only operate on flat surfaces and is limited to cutting geometries that can be represented in a two-dimensional plane.

This limitation arises from the nature of the cutting process, which involves moving the cutting tool along the X and Y axes but not in the Z axis, where depth is considered. Thus, while a 2D cutter can create intricate designs and patterns, it cannot effectively process or create three-dimensional objects since such operations require height adjustments and movement along the Z-axis.

The other options suggest capabilities or actions that do not align with the functions of a 2D cutter. For instance, a 2D cutter does not work with 3D objects, nor is it limited to merely engraving. Additionally, most modern 2D cutters are indeed computer-controlled, allowing for precise and efficient operation.
