Martin ( or others) can I force plain track into a particular angle. Im trying to ensure that when I extend a transition curve ( Length) that the track is parallel to the Grid. i.e. if I use <Curve> can I force orientation in angles to the grid as oppose to radius thanks dave |

If you want a transition curve easement to terminate in straight track parallel with the grid, put some straight track there as a dummy template, and then use the make transition functions on it. See: http://templot.com/martweb/info_files/make_trans.htm You can set the swing angle on a template: geometry > swing angles (in degrees)... menu item. You can locate a template at any desired position and angle on the grid, by setting the notch there, and then pegging onto it: geometry > notch > set notch position and angle... menu item. regards, Martin. |

when I make a curve, and I want to produce an exact 90 degree bend for example how do I know ps should there be a transition curve from straight to curve to follow prototype |

You need two templates, one to ease into the curve, and one back out. Set the swing to 45 degrees, and then make mirror on peg to create a 90-degree curve with easements at each end. If that's not clear I will make you a bit of video. p.s. you seem to be thinking in a CAD mindset? Real railways don't make exact 90-degree bends. regards, Martin. |

You do need to put yourself in the position of a p.w. engineer building a real railway, not someone assembling a model railway. For that you need a program such as AnyRail or XTrackCad instead. I will make a bit of video shortly. regards, Martin. |

Thats a bit harsh, actually I'm getting on great with Templot, and have now done all the combinations i need in the " real" layout . from reading around actually most uses dont use Templot to plan the layout but in fact use it to just print " templates" i do the design up in Trax3 first anyway to do rough sizing , the correlation between it and templot isn't bad at the end of the day I have to solder track that has to fit on a baseboard, that means it goes around 90 degree bends , even if Network Rail frowns on me . re the video , I just saw an old one , that creates an easement , then swings in 45 degrees then mirrors it.

Sorry Dave, I didn't intend it to be harsh. It's just that if you look at the trackplans which users post here, you won't find many with exact 90-degree curves. Yes, I do remember making that video -- for a garden railway I think it was? Here's the link: http://templot.com/martweb/videos/scruffs/curly_corner.exe Like so many of them it is well out of date. It's time I made a new one. regards, Martin. |
