SOLVED: pattern on a curve is rotating the wrong way and not following the curve

I am back to working on a tubing support and once again having a lot of trouble patterning cutouts along the curve.  THe curve generates the loft very well but pattern on a curve seems to be rotating thepattern objects the opposite direction of the curve.  any ideas (the triangles will be cutout of the extrusion to decrease mass and improve the look)

    Note to anyone following this: the duplication has some difficulty following tight curves, works great on gentler curves and decided to make the cutouts circular rather than alternating triangles.  You can put more along the outside of a curve and fewer on the inside to make spacing nicer

    just curious, I fail to see any use in the pattern on a curve that doesn't follow the normal other than when you use preserve orientation

    I've had similar problems with swept or loft curves, according to support it is a tolerance issue. 
    the work around they suggested I have been using for a while now and have had fewer problems.

    Start with a cylinder surface, then make your sweep, now use the sweep to split the cylinder surface. It seems to "cleanse" the edge and normalize it.
