When I open Templot there is a Green spot at x=0.00, y=24.00. If I move the display sideways so that this would be off the screen the mark moves so that it is always at the left edge of the screen, but always at y=24.00, and never less than x=0.00. If I move the display up or down the mark moves up or down with it, including off the screen. When it moves away from x=0.00 it turns from green to black. Its doing me absolutely no harm, but its irritating me like a fly in a room, because I haven't the first clue what it or what it might be for. Can anyone assuage my itch? Allan Ferguson |

Now that you've pointed it out, it'll bug me as well. Thanks  (Nope - I haven't a clue either!) |

If you mint a template of the opposite hand, or change the scale, you will see it move up or down the Y-axis, so that the template always remains above the X-axis for printing. It is always on the screen but changes colour to black when it can't be displayed actually on the Y-axis line. It marks the origin of the main-road stock rail gauge-face before any translations are applied. You may occasionally find it useful: geometry > shift/rotate > shift to datum menu item geometry > shift/rotate > rotate to datum menu item There is a lot of this low-level maths stuff left in Templot from the days before I released the program for general use. I haven't removed it because I sometimes find it useful when testing new features.  For more information, go to the geometry > shift/rotate > settings (expert) > set datum... menu item, and click the help F2 button. regards, Martin. |

Well, many thanks for putting me out of my mysery. I don't profess to understand it, but I'm reassured to know that it's meant! I'll have a wee play later and maybe make sense of it. Allan Ferguson |
