Suggested improvements:

• Automatically fill in the correct radius of transition curves/clothoids.

• Make an option somewhere (civil design file settings?) to select if you want to give transition curve values "by length" or "by constant". If you choose by length the constant and radius should be calculated and updated automatically when you fill in the transition curve length and the curve radius in the editor. There is already a check made if the radius in the transition curves match the curve so why not correct it automatically if it doesn´t match.

• Make it possible to apply one solution and then continue to edit/improve and then have an option to save the new solution instead of the first.

• With turnouts: Make it possible to have the end turnout free or make it possible to transpose the solution when you save.

• Make it possible to save the elements in the editor as graphic elements even if there is no solution.

• If the start or end element needs to be transposed for the editor to accept it - add a button to transpose the start or end elements.
