This lscript is to create the path of an object from some curve loaded in Layout. It is something like the Curve Constraint, but instead of using just one curve to create the path you can use multiple curves. You can set the starting frame(the frame in which the object will start moving) and set the time that the object will take to complete the path in seconds. You have the option to set this time in a way that the object travels through the path at a constant speed or you can set different times for each curve used to create the path, so it goes faster in some segments and slower in others.   

You also have the option to set the speed that the object will have during the path, and like the time , you can set it to have a constant speed or have different speeds.

You decide if to set the time or the speed of the object.

If you use the Curve Constraint you can see the object travels in one direction. Another benefit of this lscript is that you can make the object travels in the opposite direction by using the Reverse option. This will allow you to make a path in which the object takes one way and you make it return to take another way.
   
Download this beta version and explore these and other options in this lscript.
Have fun!!!

The only restrictions this beta version has is in the number of items you can add to the Listbox. There is more info in the tutorial.
