*/ This one is kind of funny. It is about picture display. Pocket PC have fairly small number of pixels (240x320, latest 480x640). That is not a problem. The problem lies in format that you can draw with. It uses integers numbers, rather than decimal numbers. So when two numbers are divided, it always comes to rounding, depending on decimal number. Therefore the picture is not quite accurate as it should be. Here is an example: If you enter trusses length and trusses span equal (in my case 25) you will get right deadhang rather angled.... See picture below. Howewer, if you save this truss and transfer it over to Desktop PC, you will see no such anomaly, since desktop version has no problem drawing 'decimal' lines. This does NOT influence calculations in any way, since drawing data is derived from it.
