The solid, light line that is used to lay out a preliminary shape in drafting is commonly known as a construction line. It is a thin line that is typically drawn using a pencil or a technical pen that does not have a lot of weight or pressure behind it.
The purpose of construction lines is to provide a guide for the final drawing by establishing the basic outlines and proportions of the object being drawn. They help the drafter plan out the placement of features and ensure that the final drawing is accurate and proportionate.
Construction lines should be drawn lightly and with a steady hand so that they can easily be erased or adjusted as needed. They are not intended to be permanent parts of the drawing, but rather act as a temporary guide to help the drafter produce a more precise and detailed final product.
Overall, construction lines are an essential part of the drafting process that helps to ensure accurate and well-executed drawings.
