I am trying to generate a multi-section surface using 3 guides. It works with two of them no problem, but when I select the third guide it gives me the following error:

"Strack20204.WartBody \ Ordered Geometrical Set.2\Multi sections Surface.2 Geometric sweep or loft operator: The moving plane (perpendicular to the spine) and the guides do not always intersect.
This can be due to: 

too short guides with regards to the spine

guides parallel to the moving plane

a too large spine curvature."

Can anyone help me solve the Issue?
