What does the extruding process in graphic design achieve?

The extruding process in graphic design is primarily used to create three-dimensional shapes from two-dimensional objects. By taking a flat image or a 2D shape and extending it along a third dimension—usually depth—extrusion allows designers to generate a 3D form that retains the outline of the original shape while adding volume. This technique is particularly effective in product design, 3D modeling, and animation, as it enables the visualization of objects in a more realistic manner compared to flat images.

The other options refer to processes or effects that do not describe extrusion. For example, transforming a line into a curve pertains to techniques related to vector manipulation, creating lines is related to line art or drawing techniques, and removing the interior of an object deals with clipping paths or hole cutting, which are different actions altogether. Extrusion specifically focuses on adding depth to a 2D design, making it integral for achieving a three-dimensional representation.
