If you are a mathematician, an architect, a land-surveyor, or if you are interesting in measuring lenghts, depths and angles, MB-Ruler is an excellent application for you. This tool allows you get information you need about diagonals, shapes and solids and other objects you create in a graphic editors. You can measure these values in pixels, inches, centimeters or points.
MB-Ruler allows to create additional helping devices (such as set squares and rules) as well as measure the height and breadth of a solid or chosen space. Since these tools are transparent they can be launched with other programs without interrupting your work. In addition you can draw extra help lines, points, squares, bitmaps and texts describing the values attributed to an object.
