QRule On-screen Rule for Windows

QRule is a handy, little, stay-on-top, straight line rule to aid in design and layout of web pages, printed materials, application interfaces, desktops, etc. Also useful for plotting distances and angles on maps and satellite images.

  • The .NET Framework is a set of tools developed to operate within the Windows operating system. All new versions of Windows ship with this preinstalled. Almost 70% of all Windows XP users have this installed, as it is installed via Windows Update if you request.
