Rulers are great for straight line distances, but would a ruler be a good choice to measure the length of a river or road? What if you are measuring a distance along roads from one city to another? How would you measure curved lines with a straight ruler? Universal Desktop Ruler allows you to measure not only a straight line distance but any curved distance on the Screen. It allows you to measure quickly and accurately distances, areas and perimeters of figures on the screen. You can determine your own scale and get results in pixels and your units of measurement (feet, inches, meters, ...). It is useful for measuring distance and area on a map, finding area and perimeter in a house project for example. Additionally it has a screen magnifier function.

The calculation is designed for geometric and strength designs and checks of bevel gear with straight, helical and curved teeth. The program gives solutions to the following tasks: - Calculation of helical and straight toothing. - Automatic design of a transmission with the minimum number of input requirements. - Design for entered coefficients of safety (static, dynamic). - Calculation of complete geometric parameters (including corrected toothing). - Calculation of strength parameters, safety check. - Supplementary calculations (calculation of parameters of the existing gear, temperature rise, design of shafts) - Support of 2D CAD (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD) and 3D CAD in full calculation package (Autodesk Inventor, SolidWorks). The calculations use procedures, algorithms and data from standards ANSI, ISO, DIN, BS and specialized literature. List of standards: DIN 3971, DIN 3991 Kegelradern 1-4, ISO 6336 1-3, DIN 3965 Toleranzen für Kegelradverzahnungen 1-4, ISO 1328, DIN 3990, ANSI B6.1-1968, AGMA 2001-C95, AGMA 908-B89/95, AGMA 2003-A86/88, AGMA 2005-B88 and others.
