I am having a problem when trying to create a terrain with the Create From Scratch sandbox tool. After i draw the line along the red axis when I try to then move along the green axis the tool always goes up the blue axis. What am I doing wrong. I should mention than every now and then, it does work and I have not figured out what the pattern is. Right now the only way I can get it to work consistently is to go to the top view and draw create the terrain.
Again, what the heck am I doing wrong?
