Dear all After making a lot of progress with Templot and track building in the Autumn, the rest of life got in the way, and although I have tried to get back to track planning it's been in fits and starts, and I forgotten a lot of what I had learnt. In short, I've got stuck and rather fed up. I'm trying to draw a single slip. However, I can get the roads drawn properly to get to the crossover part. I always end up with the crossover on a transition curve, and then Templot throws up warnings. The video on making the slip part seems fairly easy to follow, but I need to get past the crossover bit to get there. I'd be grateful for any advice! Boxfile attached. 3033_231643_340000000.jpg |

Hi Richard, There's a video on how to create a diamond-crossing on transition curves at help > watch a video > Scruff Video Andrew transition diamond menu item. If that doesn't work on your system, it is also available (in poorer image quality) at: http://flashbackconnect.com/Movie.aspx?id=ib65pLfUkgNxFBDqAZSNyA2 When you have the diamond-crossing, adding slip roads is the same as for regular diamonds. However, looking at your plan, the crossing angle is very short and you may find that the radius for an inside slip is too tight. The solution then would be to go for an outside slip instead. Unfortunately there isn't a video for that, although you can work it out from partial templates in the usual way. regards, Martin. |
