About Splitting a Volume into One or More Volumes
Instead of creating a volume, you can use a parting surface or another volume to split a volume into one or more volumes. Before you split a volume, you must cut out a reference part from the workpiece to create the required reference part cutout feature. Ensure that the required features such as reference part cutouts, volumes, and parting surfaces are created before you start splitting a volume. Alternatively, you can create the reference part cutout feature while splitting the volume.
When you use a parting surface to split a volume, the original volume is split into one or more volumes. In a mold or cast assembly, you can use multiple parting surfaces to split the workpieces or die blocks into more components.
If you split a volume by another volume instead of a parting surface, one or more volumes are created in addition to the original volume. In such a case, one of the split volumes coincides with the volume that is used as a parting surface.
You can also use classified surfaces along with parting surfaces to split a volume. In such a case, you do not need to cut out the reference part, because the classified core, cavity, or undercut surfaces define the surfaces of volumes to be created after splitting.
The split creates assembly features without altering the workpiece or the die block geometry.
