... I am attempting to create a transition from the straight track to the curved one. Both sections of track are aligned on the background scan how I want them. Clicking on the straight section and selectiing transition causes Templot to tell me it can't do it- WHY? These are the kinds of things that are driving me nuts daily. I can see no difference in this than the videos I have watched in an attempt to grasp Templot yet it doesn't work. Any and all help appreciated...
