This function enables the user to define a point as the origin of the tipping coordinate system. All the tipping operations will be performed in this coordinate system, as illustrated in Figure 6.1.44. The default tipping center is the center of mass of the selected part.

The Define button enables the user to define a new tipping center. Click this button to display a dialog box illustrated in Figure 6.1.45. Refer to Section 5.1.1 for detailed description about defining point/node. The user may click nodes using mouse cursor or input values to specify the tipping center and click OK to confirm.

·                GENERAL TIPPING

For general parts, there is only one tipping center to be used as the origin of the tipping coordinate system.

·                DOUBLE-ATTACHED HALF/FULL INPUT

For symmetric double-attached geometry, the master and slave parts have their own tipping centers, which are symmetric about the symmetry plane. After the tipping center of the master is defined, the program will automatically obtain the tipping center of the slave according to the symmetry plane.

·                TWO PARTS

For asymmetric double-attached geometry, the left part and right part have their own tipping centers, which have no connection. The tipping centers for the left part and right part need to be defined respectively.
