Which Autodesk Inventor tool is primarily used for creating and editing 2D sketches?

The Sketch tool is specifically designed for creating and editing 2D sketches in Autodesk Inventor. This tool provides a variety of functionalities, such as drawing lines, arcs, circles, and creating geometric constraints that help in defining the shapes and dimensions of the sketch. The Sketch environment allows users to manipulate points, dimensions, and constraints easily, which are crucial for generating 2D profiles that can later be used to create 3D models.

In contrast, the 3D Model tool focuses on the creation of three-dimensional objects and geometries rather than 2D sketches. The Drafting tool generally pertains to creating technical drawings and detailed documentation from 3D models, while the Assembly tool is used to assemble multiple components into a single, cohesive model. Each of these tools serves a distinct purpose, making the Sketch tool the ideal choice for 2D sketching tasks within Inventor.
