create a wall sweep on an angled wall (gable end wall)

[jledgewood]

I was wondering how to create a wall sweep on a gable-end wall? I would like to show a trim board at the top of the gable-end wall that follows the angle at the top of the wall. when I try to use the wall sweep tool it seems to only let me move in the vertical or horizontal direction.

I don't think the wall sweep tool will work for that as you're only allowed Horizontal or Vert.
However you can do an inplace blended sweep and attach the sweep line to the base of the wall. Then offset the start profile to the low point and offset the Second profile to the high point.
I think that's your best option.
