Which tool is used to create a 2D sketch within a SolidWorks part?

The Sketch Manager is the primary tool used to create and manage 2D sketches within a SolidWorks part. It provides an organized interface that allows users to easily start new sketches, manage existing ones, and access various sketching tools. When using the Sketch Manager, users can select the plane or surface on which they want to sketch, ensuring that their 2D geometry is properly aligned with the part’s three-dimensional features.

The Sketch Manager streamlines the process of creating sketches by providing options for common sketch entities like lines, arcs, circles, and other geometric shapes, allowing users to focus on the design aspect rather than navigating through complicated menus. This tool is essential because sketches are foundational to creating features such as extrudes, revolves, and cuts, which are critical for building a 3D part.

While other options may mention sketch-related functions, they do not encapsulate the full range of functionality and organization that the Sketch Manager offers, making it the preferred choice for creating a 2D sketch within a SolidWorks part.
