Why do drafters need to erase construction lines?

Drafters need to erase construction lines primarily because these lines can create confusion in the drawing. Construction lines are often used as guides during the drafting process to help position elements accurately. However, if these lines remain in the final version of the drawing, they can clutter the visual representation and distract from the main details that need to be communicated. A clear and precise drawing ensures that the intended design and construction information are easily understood by anyone who reviews the document.

While construction lines serve a purpose during the drafting process, their removal is essential for maintaining clarity and professionalism in the final output. This clarity allows viewers, such as architects, clients, or contractors, to focus on the critical aspects of the design without misunderstanding or misinterpreting information due to unnecessary graphical elements.
