How do you create a 2D section view in a SolidWorks drawing?

To create a 2D section view in a SolidWorks drawing, the correct approach is to define the cutting line on the view. This cutting line indicates where the section is taken from the 3D model, displaying the interior features of the part along that line when viewed in the drawing. The section view provides a clearer understanding of complex features that might be obscured in standard orthogonal views by showing a cut-through of the part.

The cutting line can be created by drawing a line on the view from which you want to create the section. When this cutting line is defined, SolidWorks will generate the section view accordingly, producing a detailed and informative representation of the part's interior geometry.

The other methods mentioned, such as using the extrude tool, rotating the drawing, or aligning the view with the original sketch, are not applicable for creating section views in SolidWorks drawings. The extrude tool is typically used in the modeling phase to create solid features, while rotating or aligning views pertains to positioning rather than sectioning the model.
