Orientation/Twist Type - Follow Path
Under sweep Options, when you
select Follow path as the Orientation/twist type, you can select
parameters to stabilize the profiles when small and uneven curvature fluctuations
along the path cause the profiles to misalign.
Profiles always maintain a normal to the
path. Profile fluctuations are due to uneven curvature fluctuations along
the path. Unless you correct the fluctuations by selecting one of the
options, the profiles follow the path and shift to adjust to the misaligned
path.
The parameters are:
|
|
With None selected, the profile
fluctuates, preventing a smooth sweep. |
Minimum
Twist (For 3D paths only). Prevents the profile from becoming self-intersecting
as it follows the path.
Direction Vector.
Select a plane, planar face, or line to define the vector. When you select
a plane or planar face, the normal of the plane or planar face is applied.
If you select a line, the line direction provides the direction vector.
The section plane (along which the sweep
is created), always includes the direction vector as its X-axis. The normal
of the plane, the Z-axis,
is the plane that contains the direction vector and the path tangent at
that point.

The Front plane (shown) is the Direction
Vector. The profiles do not fluctuate, remaining aligned along
the entire path, and creating a smooth sweep. |
The section plane (along which the sweep
is created), always includes the face normal as its Y-axis. The normal
of the plane, the Z-axis, is the tangent of the path at that point.

All Faces selected (as shown).
The profiles do not fluctuate, remaining aligned along the entire path,
and creating a smooth sweep. |
