1. Create a 2D line where you want the bend to be. (Position a workplane on the sheet's face, and use the options on the Modeling tab, in the Draw group to do this.)
2. Activate the Basic Sheets module:
a. Click File > Modules. The Modules dialog box opens.
b. Click Modules.
c. Click Basic Sheets under Free.
3. Click Sheets and then, in the Modify Sheet group, click the arrow next to Bend.
4. Click Create. The Create Bend dialog box opens.
5. Click the Face where the bend is to be placed.
6. Click the Lines along which the bend is to be formed.
7. Specify the part of the sheet (the Anchor Pt) that is to be held while the other part of the sheet is folded. (What you are doing here is defining a 3D point that does not change when using the Next command.)
8. Depending on where you want the bend to start, click Centered on or off. (See the figure below.) The default is not centered.
9. Specify the bend attributes under Bend Attributes:
◦ Angle: The angle of the bend relative to the defining face.
◦ Inner Rad: The inner bend radius.
◦ K Factor: The K factor for the part.
10. If necessary, click Reverse to reverse the bend direction.
11. Click Next to retain the bend attribute settings in the menu and continue bending parts.
12. Click Preview to preview the bend, or click to complete the operation.
When creating bends, note the following points:
The Centered command specifies whether or not the bend is done either side of the bend line (picture 2) or from the bend line (picture 3):
Bending along infinite construction geometry:
Bending is done at all points on the face along the construction geometry even if the construction geometry appears to be of finite length.
Bending along real geometry:
Use the Select command to select several bend lines. Note that the 2D geometry does not need to completely traverse the face. It needs only to lie on part of the face.
Multiple bend lines must belong to the same infinite line:
Bending together in figure 1 is possible. In figure 2, it is not.
For bend angles less than 90 degree, the projection line passes through point P. For bend angles greater than 90 degree the point of curvature passes through the vertical projection of P.
