Array 2S Y spline behavior

[TL1895]

I am trying to make a glass curtainwall based on the spider tutorial.
Only difference is that I won't have any spiders or supports in this version...only the glass panels.
So, I think I have things close, but the Y spline alignment is driving me nuts.
Please see pic...it either is offset and rotated wrong, or just offset from the true spline.

I've tried reset-xfrom, adjusting the  RC style, etc, with zero affect, except one time changing the x-rotation to 90 fixed it.  But then I had to change the spline, and it won't realign no matter what.

One other thing I cannot get right is the weird thing happening at all the corners and ends of the splines.  I turned off "bend" in the segment, but it didn't help.

Here is an example of what I'm going for, fairly simple, I think...


edit:  Ok, sorry, I figured it, out.  i had my x and y splines mixed up I think.  I got rid of the one for height and set Y mode to free.  Now It works great.
