How does modeling differ from carving in sculpture?

In sculpture, modeling and carving represent two fundamentally different approaches to creating form.1

Modeling

Modeling is an additive process in which the artist builds up form by working plastic materials, such as clay or wax, by hand. Because the artist starts from an internal structure and adds material outward, modeled works often exhibit greater spatial freedom and expansiveness compared to carvings. A key advantage of modeling is that the process allows for corrections as the work progresses. Many artists choose to preserve the tactile record of their direct manipulation of the medium in the finished piece.12

Carving

Carving is a subtractive process in which the artist cuts away portions of a hard substance, such as stone or wood, to reveal the final form. Unlike modeling, carving is limited by the original dimensions of the material block. The process requires specialized tools—such as chisels, gouges, or rasps—to remove material, and the final result is typically more permanent than modeled works. While modeled work can be reproduced in stone or metal through casting or mechanical pointing, carving remains a distinct technique defined by the removal of material.123
