What is represented by dashed lines in an assembly drawing?

In assembly drawings, dashed lines are utilized to represent hidden parts or features of the drawing. These hidden lines indicate elements that are not visible from the current view being depicted, allowing the viewer to understand the full configuration of the assembly. A dashed line typically signifies that the part it represents exists behind or within another object, helping to convey important information regarding the geometry and structure of the assembly without cluttering the drawing with additional views. This practice is essential for accurately portraying complex assemblies where certain components might be obscured from sight in a particular orientation. As a result, hidden parts can be clearly communicated and understood by anyone reading the drawing, ensuring accurate assembly and maintenance.
