I just started implementing the height functionality.
It roughly works like this:
- Select a piece of track (or more)
- In the context tab, there is a height input field. Enter a value or use the spinner buttons to increase or decrease height.
The track will move up or down, taking the connecting track with it. It will take into account the maximum slope you find under settings. This way you can create gradual slopes.
I am very interested in your feedback. Is it working? Do you find it intuitive? How can we improve on it?
