Thank you Lisa,
That video is very informative
, have seen in a few seconds where I have be going wrong doing something else, I see its a bit of working out what the shape is then pull or pushing bit afterwards.
Now try out following it as it played .
edit
been watching the video and I am a bit lost on how you are getting the vectors into a straight line.
I see when you drag over them, they turn green, what I can't make out is do you press a key to line them up or what, can't get it to do that bit.
cheers
