Example: Create a guided loft with orientation options
In Guided Loft, a local coordinate system moves along the spine in order to reference how profiles are turned when swept along a spine. Use an orientation option to influence how a profile is turned along a spine.
The Orientation Options work the same way as the options By Spine, By Constant Birail, and By Face in the Advanced Sweep command.
The Orientation Options include:
By Spine - The default orientation that minimizes the twisting of the profiles around the spine. If the spine is planar, the U direction is constant and the profile does not turn around the spine.
Orientation option: by Spine
Orientation option: by Spine with planar curve
By Guide Curve - Use a second curve to define the twisting of the profile along the spine. The U direction is calculated by intersecting the plane of the spine with the guide curve. The guide curve must be as long or longer than the spine.
Orientation Option: by Guide Curve
By Face - Use this option to connect a guided loft surface tangentially to an existing face. The U direction is calculated by using all the tangents of the face along the spine. If the profile is not tangent to the face where it touches the spine, the angle between the profile and the tangent is kept along the spine. In the example below, the angle is 0 and is kept along the spine. A smooth transition between the guided loft surface and the face is generated.
When there are two faces attached to the spine, click Side to switch between faces.
Orientation Option: by Face
