Bend along a line

This command allows to bend a sheet along a line or an edge.

Creation stages / Use:

Click the icon or select Sheet Metal > Bend Along Line... from the drop-down menu.

Select the face(s) to bend.
Select a bending line type (extended line, line or edge).
Depending on the chosen selection mode, select :
- either a line then an edge on the fixed side of the sheet (this edge must not intersect the bending line).
- or an edge of the face to bend.
Enter the bend parameters (inner radius, angle, position).
Validate the creation of the bend with the button.

The bending line must be created beforehand in a sketch with only one segment.

Available Options:

You can select several faces to bend.

To allow this type of bend, these faces must be coplanar:

Selection of 2 coplanar faces enabling to bend this shape in this area

The bending line may be defined by a line (sketch) or an edge:

Extended line	Line	Edge
The bend line is extended on all the face to bend.	The bend is carried out along the length of the line (this must be at least equal to the length of the part to bend).	The bend is carried out on the selected edge. This edge must not be connected to a lateral face.

The bend line is represented in red

This section allow you to define the bend parameters for a bending line like Extended line or Line:

	Manual: Enter the inner bend radius.
	Thickness: The inner bend radius is the thickness.
	Unfolding rule: The inner bend radius is defined by an unfolding rule regarding the thickness and the material.

Rolled	The face of the bend starts at the bend line.
Thickness under the line	When we are placed between the fixed edge in green and the bend line in red, the thickness of the bended sheet is located under the line.
Thickness on the line	When we are placed between the fixed edge in green and the bend line in red, the thickness of the bended sheet is located on the line.
Centered	When the sheet is flat, the bend is centered on the bend line.

the shift allows to move the bend in parallel with the line, its value can be negative.

Whole face: The goal is to have a rolling of the face which matches with the length of this face (by taking into account the used unfolding rule).

	Given angle: Enter the angle. The radius is automatically calculated.
	Given radius: Enter the radius. The angle is automatically calculated.
	Given angle and radius: Enter the angle and the radius. In this cas, the unfolding rules aren't taken into account.

This Whole face option is rather destined to TopSolid'Strip.

This section allow you to define the bend parameters: it is not available if Whole face with Given angle is checked.

	Manual: Enter the inner bend radius.
	Thickness: The inner bend radius is the thickness.
	Unfolding rule: The inner bend radius is defined by an unfolding rule regarding the thickness and the material.

	Check this option to limit the face to bend by a profile (open). This profile must have two intersections with the bend line.
	Example: The bend line is in red, the trimming profile in green.

	Clearance can be indicated between the reference face of the sheet and the bent face, checking the Invert box positions this clearance inside or outside the trimming profile.

Check this option to create a dimpling.

Enter the dimpling height.

Select the dimension position .It can be between external faces, between internal faces or a global dimension.

A second bending radius can be entered. By default, it has the same radius than the face to bend.

Refer to the unfolding rules command for more details.

Hide tools: This option allows to hide or not the sketch of the selected line.
Allow surface result: If errors are found, a message is displayed and you can get a surface shape thanks to this option.
