• By Offset—Adjusts the selected trimming chain of a ply or a core by a specified offset distance. When a laminate object contains an outer and an inner loop, the laminate object can be trimmed by making the outer loop smaller or inner loop bigger. To learn how to trim a ply boundary by specifying an offset value, see Trim ply boundary by offset.

• By Reference—Specifies the area to keep and the area to trim using a reference, such as connected edges, chains, chain segments, or a plane. You can use this method to trim the boundary of only plies. You can trim more than one ply at a time. To learn how to trim a ply boundary by specifying a reference, see Trim ply boundary by reference.

• By Contour—Eliminates the area of the ply intersected by a closed loop contour. You can use this method to trim the boundary of only plies. You can use an existing loop or create and use curves. The new ply boundary is the outline of the remaining ply area. To learn how to trim a ply boundary by removing the area intersected by closed-loop contours, see Trim ply boundary by contour.
