Hi Michael,

There are two issues: a faster workflow and having the rail follow and stick to the form's (cushion) edge.

You can see the rail separates from or overlaps the cushion edge. Adjusting the points in 3D and is about 75% successful and very time consuming. This can result in gaps or the piping cutting into the cushion which will not be seen except in a close up.

Moi3D makes this amazingly simple except for this one part which sounds like I am, again, missing a setting.

Thanks,

Leonard
