(v) Plotting Control: Layers allow you to control which layers are included or excluded when plotting a drawing. This functionality enables you to create different plot configurations for different purposes, such as printing specific layers separately or excluding certain layers altogether.

(vi) Collaboration and Standards: Layers provide a means to enforce drawing standards and facilitate collaboration. By defining layer properties and assigning objects to specific layers, multiple users can work on the same drawing while maintaining consistency and ease of coordination.
