What line connects notes, text, or identifying labels in a plan?

The correct choice is leader lines and arrows because these are specifically designed to connect notes, text, or identifying labels to the elements they describe in a drawing or plan. Leader lines typically originate from a specific point on the drawing and lead to the accompanying text, ensuring clarity by visually linking the annotation to the relevant portion of the plan. This makes it easier for anyone reviewing the documents to understand what is being referenced.

Centerlines are used to indicate symmetry or the center of features and do not serve the purpose of connecting notes or text to specific points. Solid lines represent the edges of objects or structural elements, lacking the specificity needed for annotations. Break lines are used to signify that a portion of an object has been removed or is not shown in full for clarity but do not function to connect notes or labels. Hence, leader lines and arrows are the most effective choice for linking descriptions to the corresponding features in architectural or construction drawings.
