Object Properties
Isoparm Subdivision
Denes the number of isoparms used to display the Sweep NURBS when the isoparm display mode is
active.
Scaling
Determines the size of the contour at the end of the path. The contour is 100% at the start of the path
and the size is interpolated in between.
Rotation
Denes the rotation about the Z-axis that the contour has passed through by the time it reaches the
end of the path.
Growth
Denes the size of the sweep. 100% means the contour spline is swept along the entire path. If the
path is closed, you can set caps (but not rounding) when the growth is less than 100%.
You can animate the growth by recording the Growth parameter. For example,
you can gradually write a word by using a circle spline (e.g. radius 4, XY plane)
as the contour and a spline in the shape of the handwriting as the path. Finally,
record two keyframes for Growth.
