What mode should SolidWorks be in to create two-dimensional geometry?

To create two-dimensional geometry in SolidWorks, the software must be in Editing Sketch mode. This mode is specifically designed for sketching and allows users to create and manipulate 2D shapes using various sketch tools such as lines, circles, and arcs. When in Editing Sketch mode, the workspace is set up to facilitate drawing and dimensioning, which are essential for creating 2D geometry that can later be used to define 3D features.

In this mode, users can employ constraints and relations to control the geometry's behavior, ensuring that it meets design requirements. The focus on 2D construction makes it the ideal environment for initial design phases before transitioning to 3D modeling.

In contrast, while Assembly mode is used for bringing together different parts in a model, and Part mode allows for the creation and modification of 3D objects, these modes are not specifically tailored for drawing 2D sketches. Simulation mode, on the other hand, is utilized for analyzing models and does not offer tools for creating geometric shapes. Thus, Editing Sketch mode is the most appropriate choice for creating two-dimensional geometry within SolidWorks.
