TRIM

This function is used to trim a blank using a closed curve trim line(s). The trimming will be processed based on a defined vector/direction. The user can decide to keep the elements inside/outside of the trim line. These elements are included in a new part called TRIMOUT.

After a trim line is selected, the user has to define a vector (direction of projection) for the trim curve, that is, W-direction or global Z-axis, from the LSC dialog window (as described in Section 2.9). The user can then set the trimming tolerance from the dialog window as shown in Figure 9.7.3. The trimming tolerance ranges between 0 and 1. It limits the size of the small elements generated during the trimming operation. A larger tolerance produces large elements, and a smaller tolerance gives small elements and more detail in the trim line. The default value is set to 0.30.

Note: Prior to the trimming operation, the user must define the blank properties.
