Hello everyone,
I made a Spline with the landscape tool. Then i deleted all landscape components because the spline should fly and I don’t need any landscape ground in my scene. But now I want to modify my spline again but to great new points I need the ground which i deleted before. So now I have 0 components in my scene but i want them back. Is there any way to create new components if you have 0 components in your scene? 
would be great!
