While sketching a line, how can one switch to the Arc tool?

Switching to the Arc tool while sketching a line can happen through a process known as auto-switching. In SolidWorks, when you are creating a line and you need to switch to drawing an arc, you can simply begin to drag the cursor in a relevant direction. The software intelligently recognizes the action and can automatically switch the tool from Line to Arc based on the motion. This feature enhances the fluidity of the design process as you can maintain the continuity of your sketch without needing to manually select different tools through icons or menus.

Utilizing the auto-switch feature allows for greater efficiency, especially in scenarios where you frequently transition between lines and arcs. This is beneficial in creating complex shapes and paths quickly without interrupting the workflow to change tools. Other methods such as clicking the Arc tool icon, double-clicking the line, or applying a shortcut key would require additional steps, making them less efficient compared to the seamless experience of auto-switching.
