Hide/Unhide

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.

Delete

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.

Generate

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.

Subdivision Type

Determines how you specify the number of subdivisions in the result.

• Per Span uses the “natural” subdivisions as determined by the shapes of the inputs. You can subdivide each segment further using the U and V span sliders.

In this case, discontinuities resulting from multiknots in the inputs are preserved in the generated objects.

• Absolute allows you to set the total number of subdivisions using the U and V abs sliders.

U, V span

The number of subdivisions corresponding to each segment of the inputs, when Subdivision Type is Per Span.

U, V abs

The total number of subdivisions, when Subdivision Type is Absolute.

Start Position, Length

The start and end positions of the extruded surface in SOFTIMAGE units. Note that Start is available only if Snap to Profile is off.

From Center

Controls how the profile is aligned with the global center. At 0, the profile’s center is aligned on the guide, and at 100 the minimum U boundary is aligned. Values in-between align a point between the center and the minimum U boundary; values below 0 and above 100 extrapolate beyond these points. This option is not available if Snap to Profile is on.

Snap to Profile

When on, the extruded surface is created at the position of the profile curve. If it is off, it is created at the global center.

Local Axis

Controls whether the extrusion occurs along the object’s local axes (on) or the scene’s global axes (off).

Extrude Along X, Y, Z

These options specify an axis along which to perform the extrusion: X, Y, or Z. When any of these options are on, any guide curve you picked is ignored. When multiple options are on, the extrusion is performed around the corresponding unit vector. For example, if both Extrude Along X and Extrude Along Y are on, the extrusion is performed around the vector [1, 1, 0].
