I was going fine until I came across this question:
The rails will be creating by applying a bevel object to the path. In front view, create a shape for a rail - something like this:
Scale the shape down, and duplicate it. Join the curves together by selecting them both, and pressing CTRL-J.
In the bottom-right of the screen, you can read the object’s name. It’s probably something like OB:Curve.001 (it is for me, anyway). Now select the main path, go to the edit buttons screen and enter the object name you just found in the BevObj: field.
I don’t know what I am supposed to do.
Does anyone else?
Am I supposed to make a shape, out of a plane, curve or something else?
bev ob is when you create 2 curves, and type the name of one of the curves into the ‘bev ob’ field ( in edit buttons ) of the other one, and the one becomes the skin for the other.
you can make them straight by selecting the bezier handles in edit mode, and scaling them using the s key. the smaller you make them, the sharper the falloff will be.
