Creating a Parting Surface Manually

You can create the parting surface manually in circumstances where the skirt surface does not provide the desired shape.
• You can use a combination of manual parting surface and skirt surface techniques.
• To manually create a parting surface:
– Start the Parting Surface tool.
– Create all surface features for a loop.
– Merge the surfaces together.

Sometimes the silhouette curve and skirt surface features do not provide you the desired parting surface shape. You can create the parting surface manually in these types of circumstances. You may also use a combination of a skirt surface and manual parting surface for a mold model. The skirt surface can be used for the parting surface in the locations where the proper geometry has been created, and a manual parting surface can be created in areas where the skirt surface does not provide the desired shape.
To create a parting surface manually, you can click Parting Surface the Parting Surface & Mold Volume group and then use the various basic
and advanced surface creation techniques. Each of the surfaces created belongs to the parting surface feature. You can also use the various editing and manipulation tools on the surfaces.
After all surfaces have been created for a given loop area in the mold model, you must use Merge the parting surface feature.
to merge the surfaces together before completing In Figure 2, a total of three surfaces were created to close the loop and create the parting surface. Two surfaces are fill surfaces, and the third surface is an extruded surface. Once all three surfaces were created they were merged
together. At this point the silhouette curve could be used to create the outer loop of the parting surface and to fill the hole shutoff in the boss.
