Toroidal Bend

    The Toroidal Bend command bends solids, surfaces or datum curves into shapes.This command is used to create tire-like structures,where you need to create operations on a flat surface and then bend it.

    The Command creates two blends.You can bend the section with a bend profile and then create a toroid.A coordinate system should be defined in bend profile to define the neutral plane. The following task explains how to create a toroidal bend.

To create Toroidal Bend:

1. Open the part file toroidalbend.prt.
2. Choose Insert > Advanced > Toroidal Bend… from the Main Menu.The Menu Manager appears displaying the options for toroidal bend.

-          Variable, 90,180,270 and 360: Specify the toroidal bend angle.

CrvBendContract: Datum curves are contracted radially while bending.

CrvBendExpand: Datum curves are not contracted while bending.

CrvFlatContract: Datum curves remain planar and are contracted with the neutral plane.

CrvBendExpand: Datum curves remain planar and are expanded within the neutral plane

3. Select 360 > CrvBendContract in the OPTIONS menu and click Done.
4. In the DEFINE BEND menu click ADD. Select the top surface of the modeland then click Done.
5. Now,Pro/E prompts you to set a sketching plane to draw the bend profile. Select the sketching plane and accept the default normal direction.
6. Select Default as the SKETVIEW. Add left and right edges as references in the References dialog box.
7. Construct the sketch with the coordinate system.
8. Exit the Sketcher Window.
9. Select the two ends of the model to define the references for the toroidal bend.
10. Hence the Toroidal Bend is created.
