Morph Tool for a curved and sloping wall

[TomFalck]

When adding a wall as hand rail to a circular stair, and morphing is applied to the wall to create a sloping wall, the wall ends stay perpendicular but the centre part of the wall leans out at about 4 degrees. . This is very prominent in the 3D window and looks bad. How do I rectify this?

I don't know why this happens (I assume it happens when the Wall is converted to a Morph).
To work around this issue, try to create a Morph cutting body at the top, and use SEO to cut this Morph from the Wall to achieve the sloped top surface for the Wall. That may give you the solution you need.
