I need to add a transition to an existing curve in the following situation:
Element 1 - Line between two points (Fixed)
Element 2 - Arc Between Elements (Free)
Element 3 - Curve Between Points (Fixed)
Elements 1 and 3 are placed first, then element 2 is placed as an Arc Between Elements (Spiral/Arc/Spiral). This allows me specify the ahead and back transitions on element 2. However I cant see a way to add a leading transition to the third element. Any ideas?
