Part VII: Working with Specialized Functionality
Parting Lines
The Parting Lines feature identifies (automatically or manually) the edges that separate the cavity
faces from the core faces. Figure 32.22 shows the PropertyManager as well as the preview for this
feature. The edge selections for this feature were mostly manual. SolidWorks intends for you to use
the red arrow shown after you select an edge to propagate the selection around the part by press-
ing Y for yes if the red arrow indicates the correct next edge of the Parting Line or N for no if it
does not.
FIGURE 32.22The Parting Lines interface
In the example shown here SolidWorks gives me a message that says that the parting line is a com-
plete loop around the part, but the part has some through holes, so it requires shut-off surfaces to
close the holes.The Parting Lines feature can also split faces if need be. You might need to split a face that strad-
dles the parting line. For example, a filleted face might bridge across the parting line and need to
be split.
