Profile Section collector—Collects an internal sketch or an external sketch that defines the profile section. The profile section must contain a rotatable geometry coordinate system to indicate the neutral plane. The neutral plane is coincident with the xz-plane of the coordinate system. For internal profile sections, you cannot exit Sketcher and continue creating the feature without creating a valid coordinate system.

For internal profile sections, you cannot exit Sketcher and continue creating the feature without creating a valid coordinate system.• Bending methods list—Specifies the method of defining the toroidal bend:
◦ Bend Radius—Sets the distance between the origin of the coordinate system and the bend axis.
▪ Bend radius box—Sets the value of the bend radius.
◦ Bend Axis—Lies on the profile section plane. It is parallel to the x-axis of the geometry coordinate system.
▪ Axis collector—Collects the axis to bend around.
◦ 360 degrees Bend—Sets a full bend (360°). The bend radius is the distance between the two planes divided by 2π.
▪ Bounding planes collectors—Collects two planes, one at each end of the geometry to bend.
Tabs

◦ Quilts and/or a solid body collector—Collects one body, any number of quilts, or a combination of one body and quilts to bend.
◦ Curves collector—Collects all the curves that belong to the bending geometry feature.
◦ Profile Section collector—Collects an internal or an external sketch for the profile section.
▪ Profile Section Edit—Edits the selected profile section sketch.
◦ Normals Reference Section check box—Activates the Normals Reference Section collector.
▪ Normals Reference Section collector—Collects an external sketch as the reference for the normal vector direction of the toroidal bend. When a normals reference section is applied, it references the profile section. Place it as close to the profile section as possible. Avoid the area where the profile section is not tangent or has high curvature. The normals reference section must be long enough for all points in the profile section to have a projection on it. Preferably the two sections either coincide where the curvature is low, or one is an offset of the other. There are two ways to create this dependency:
▪ Create both sections as external sketch features.
▪ Create the profile section as an external sketch feature and the normals reference section as an internal sketch of the toroidal bend feature.
To implement a feature containing multiple internal cross-referencing sketches, first create the profiles section and then the normals reference section. The Sketcher setup for the normals reference section is then automatically selected to be the same as the profile section and cannot be modified within the normals reference section sketch.
▪ Normals Reference Section Edit—Activates Sketcher to edit the normals reference section sketch.
• Options
◦ Curve Bend—Defines the algorithm that is used to bend curves.
▪ Standard—Bends the chains according to the standard algorithm for toroidal bends.
▪ Preserve length in angular direction—Bends curve chains so the distance from points on the curves to the plane of the profile section is maintained along the angular direction.
▪ Keep flat and contract—Keeps the curve chains flat and in the neutral plane. The distance from points on the curves to the plane of the profile section is shortened. If a second toroidal bend is created with the Preserve length in angular direction option, the result is equivalent to creating a single toroidal bend with the Standard option.
▪ Keep flat and expand—Keeps the curve chains flat and in the neutral plane. The distance from points on the curves to the plane of the profile section is increased. If a second toroidal bend is created with the Standard option, the result is equivalent to creating a single toroidal bend with the Preserve length in angular direction option.
 | You can apply the nonstandard options only if the curves to bend lie on the neutral plane. |
