What is a "ruling pen"?
A ruling pen is a tool used for drawing straight lines or creating fine, precise lines with ink or other liquids. It consists of a metal nib that can be adjusted to control the width of the line by changing the gap between the two nibs. Ruling pens are often used by illustrators, architects, and graphic designers for tasks that require consistent, straight lines or detailed work. The tool can be used with ink, watercolor, or other media, making it ideal for technical drawing, architectural plans, and decorative art.
Example
The architect used a ruling pen to draw precise parallel lines for floor plans, ensuring accuracy and uniformity in the design.
During the drafting class, students learned how to use a ruling pen to create clean and crisp lines for engineering diagrams.
