This bend side is further identified by the presence of a straight arrow anchored on the open profile and pointing toward the bend side. Also, the direction of the bend is indicated by a curved arrow. Options in the dialog box allow you to flip these directions independently. If this is the case, right-click in one of the edit boxes for entering bend parameters. A shortcut menu will appear, and you can select Pan, Zoom or 3D Orbit from this menu to change your viewpoint and zoom level for a better look at your part.
Bends always start at the bend profile-the profile becomes one of the bend's two tangent lines.
The inside bend radius of 90-degree bends must be equal or larger than the maximum thickness of the part's cross section. The plane of the bend profile can be on the top surface, the bottom surface or within the part you want to bend. You must, however, set the bend radius to a value that matches the part's thickness and the plane of the profile. If the bend profile is in the middle of the part, the minimum bend radius for 90-degree bends will be 9mm for either direction. To precisely position flanges and holes on bend features, you must adjust the location of the bend profile to account for the curved length of the part's surface through the bend.
