3. Then move it forwards. When you do this, put your cursor over the arrow pointing along the axis that you want to move the line so the stick turns orange. This restricts the movment to that axis so it wont go all over the place.
I'm trying to do this but it doesnt have any arrows. Its really annoying having to go to the toolbar to change the axis restrict thing, caus ei cant seem to turn it off and theres no xyz button - just x, y, z, xy, yz, xz. I know what the other arrow thing should look like as i had it before but i cant fing whats turned it off, and it wont come back.
