It was manufactured for practical use at work sites and provides accurate figures using trigonometric functions and CAD. However, errors may occur depending on the individuals processing ability, so please use it for reference only.TNP (tray & pipe) consists of a total of 5 screens, and the menus are divided into a b c d e.The first a is a screen for processing tray S. If you select the standard and angle and enter the height, you can obtain the hypotenuse value and check the cutting value and perforation value.The second b is a screen for processing the tray horizontally and vertically. By entering the size and width, you can get the cut value and height value.For the third c, you can get the difference value by entering the angle and spacing to obtain a constant spacing value when the tray and pipe are installed uniformly vertically.The fourth d is for conduit and copper pipe bending. If you enter the angle and height and get the value of the hypotenuse, you can mark two points and band them at once.
