now i did not know how to extrude a pth cruve so i use a simple poly curve 3D curve
and the animation seems ok in front view but there is a roation of 180 degress ewhen it arrive at the top part
so how to correct this rotation and this is due to what ?
to solve this you have to make the curve in top view instead of front view
cause the Z axis must always point up for instance
or change the axis constraint in object panel F7 may be!
sothat there is not rotation when going from bottom part to top part of the curve
so that the Z axis or Y axis always point in same direction!
