True or False: Object lines are always drawn as a thick solid line.

In drafting and technical drawing, object lines are indeed represented as thick solid lines. These lines are fundamental as they define the edges and outlines of the objects in a drawing, providing clear and unambiguous shapes. The thickness of the line helps to emphasize the primary elements, making it easier for viewers to differentiate between the various components within a drawing.

The understanding of the object's boundaries is crucial in both architectural plans and engineering diagrams. By utilizing thick solid lines for object representation, drafters ensure that the most important information is presented prominently, aiding effective communication of design intent. While there may be other types of lines used in drawings for different purposes (such as hidden lines or center lines), the standard for object lines remains a thick solid line.
