Loft creates a surface or polygon mesh that spans a series of cross-sectional profile curves.
To apply: See Lofting Curves [Data Exchange].
To redisplay: Select the lofted object then choose and click the tab.
Inputs
|
Hides all the inputs for the generated object to simplify the display of your scene in the 3D views, or unhides the inputs
when you need to modify them.
|
|
Freezes the generator and deletes the inputs. This simplifies the scene once you are satisfied that you won't need to modify
the inputs again.
|
Automatic Uvs
|
Automatically generates explicit texture UV coordinates. The UVs created in this way are evenly spaced according to the number
of segments (edges or knot curves) in each direction.
The UV generation is "live". If you change the number of subdivisions set in the generator operator, the UV coordinates are
automatically updated. If you change the number of subdivisions after you have manually edited the UVs, you probably won't
get desirable results because the UV indices have changed. If you freeze the UV coordinates, the generator operator is frozen as well.
Clicking this button multiple times does not generate multiple UV projections.

Subdivisions
|
Determines how you specify the number of subdivisions in the result.
-
uses the "natural" subdivisions as determined by the shapes of the inputs. You can subdivide each segment further using the
and sliders.
In this case, discontinuities resulting from multiknots in the inputs are preserved in the generated objects.
-
allows you to set the total number of subdivisions using the and sliders.

The number of subdivisions corresponding to each segment of the inputs, when is .

|
The total number of subdivisions, when is .

Start, End Surface
These parameters apply only when the first or last curve in the loft operation is a curve on a surface; e.g. a boundary or
isoline.
|
The continuity between the lofted surface and the original input surface.
-
() The lofted surface begins or ends at the position of the surface curve but does not take into account the tangent or curvature
of the surface. The result can be a sharp edge between the lofted surface and the input surface.
-
() The tangent of the lofted surface is aligned with the tangent of the input surface at the boundary. The result is a smooth
transition from the lofted surface to the original surface.
-
() The normal of the lofted surface is aligned with the normal of the input surface at the boundary. This results in an even
smoother transition between the surfaces.
|
|
Affects the extent of influence of the original input surface's shape on the lofted surface. This parameter does not apply
when is () .
|
|
Applies continuity between the lofted surface and the original input surface laterally (i.e., in V). Again, this parameter
does not apply when is () .

Open/Close
Specifies whether the lofted surface is open or closed in and . These option work only if the corresponding input curves are open. If the input curves are closed, the surface will always
be closed in the corresponding direction.
