Susan...cont:
took the curves of one side of your slide
found the center of each segment so I had the radius and the included angle of each
redrew the plan using radii to the nearest foot and angles to the nearest multiple of 15deg (using circles with 24 sides each...so each segment was again 15deg)
copied the new curve and offset 24" and 48"
Now I have a plan that will work with the previous "tut". You may want to change the angle to 7.5deg for smoother slide...? What ever you decide on the number of segments (including any "straight" sections at top and bottom), divide the total drop by the number of segments to get the autofold offset. (If you think some sections slope more or less...adjust the offset accordingly.)
Hope this helps to clarify.
