Drawing boards are traditionally free-standing or positioned on a desk. A drawing board tends to feature a ruler that is usually parallel or slidable on the board. The primary purpose of a drawing board is to help in professional, technical and creative drawing tasks. They also offer a workspace where architects, students and designers can draw and illustrate their plans. The horizontal ruler that you get with Vistaplan drawing boards will move freely whilst keeping your work pinned and maintaining its parallel position on the board.
