Surface Loft |
The Loft command fits a surface through selected profile curves that define the surface shape.
Adjust seam options |

Flip |
Reverses the curve direction. |
Automatic |
Attempts to align the seam points and directions without intervention. |
Natural |
Moves the seam points to the way they were at the beginning of the command. |
Command-line option |

Point |
Allows picking a location for the start or end of the loft at a point. This tapers the loft to the selected point. No point object is necessary, but it is a good idea to have some reference geometry in place to aid in picking the point location. Point steps

Loft Options
Determines the knot and control point structure of the surface.
When some, but not all, endpoints of loft shapes touch, the loft type is restricted to Straight sections to avoid self-intersecting loops in the resulting surfaces.
The surface control points are created at the same locations as the control points of the original. This is a good option if the control points will be edited later.
The surface has an average amount of stretching between the curves. This is a good choice when the curves are proceeding in a relatively straight path or there is a lot of space between the curves.
Creates a ruled surface. The sections between the curves are straight.
The surface closely follows the original. This is a good choice when the input curves are going around a corner.
Makes the object knot vectors uniform.
Creates a closed surface, continuing the surface past the last curve and around to the first curve. Available when you have selected three shape curves.
If the start curve is a surface edge, the lofted surface maintains tangency with the adjacent surface. You must use at least three curves to activate this option.
If the end curve is a surface edge, maintains tangency with the adjacent surface. You must use at least three curves to activate this option.
If checked, the loft creates a single surface.
If unchecked, the loft creates a polysurface when the input curves are joined tangent curves. Faces in the resulting polysurface correspond to the tangent sub-curves in the input curves.
Click the end of a shape curve to reverse the direction.
Curves will not be rebuilt.
Rebuilds the shape curves before lofting.
Refits the shape curves to the specified tolerance value.
