A long dashed line is a type of line used in technical drawings and illustrations to represent hidden or obscured features. It is a line consisting of a series of dashes, each of which is longer than the gaps between them. The length and spacing of the dashes can vary depending on the purpose of the drawing and the conventions of the industry or field in which it is being used. Long dashed lines are commonly used in architectural drawings, engineering diagrams, and other technical illustrations to indicate features that are not visible from the viewer's perspective or that are obscured by other elements in the drawing. One of the key advantages of using long dashed lines in technical drawings is that they allow the drafter to convey a large amount of information in a relatively small amount of space. By using different types of dashed lines, such as long, short, or double-dashed lines, the drafter can indicate different types of features, such as hidden edges, centerlines, or boundaries between different materials or components. This can be particularly useful in complex drawings where there are many overlapping features or where the viewer's perspective is limited. Another advantage of using long dashed lines is that they can help to make technical drawings more visually appealing and easier to read. By breaking up solid lines with dashes, the drafter can create a sense of texture and depth that can make the drawing more engaging and easier to understand. Additionally, long dashed lines can be used to create a sense of movement or directionality, which can be useful in conveying the function or purpose of a particular feature or component. Overall, long dashed lines are an important tool in the technical illustrator's toolkit. They allow drafters to convey a large amount of information in a small amount of space, while also making drawings more visually appealing and easier to read. By mastering the use of long dashed lines, technical illustrators can create accurate, detailed drawings that are both informative and engaging.

As an architectural draftsman and technical illustrator, long dashed lines are a common tool used in drawings to represent hidden or phantom lines. These lines, also known as “hatching”, are an important part of creating an accurate, detailed plan. The use of long dashed lines can be seen in almost any type of architectural drawing, such as floor plans, elevations, sections, and details. Long dashed lines can be used to indicate a variety of things, including openings, walls, doors, windows, and other features. Long dashed lines are used to represent something that may be out of sight or hidden, such as a wall behind a door or window, or an element that is not visible from the point of view of the drafter. Long dashed lines can also be used to represent a part of a feature that can be seen but is not necessarily visible, such as a corner of a wall or a portion of a roof. In some cases, long dashed lines may be used to indicate a certain material, texture, or color.
