      <p class="para_topic">Solid Patch is an alternative to modeling surfaces for shut-offs. Solid Patch is most useful when it's easier to form a solid to fill an opening than to model sheets. An example of a feature that lends itself to using Solid Patch instead of surface patch is most hook latches.</p>
      <p class="para_topic">The procedure to use solid patch is to first model a solid that fits the opening on the parting part and also has the faces with correct angles for shut-offs. Use the Solid Patch function to unite the shut-off patch body to the parting part model. </p>
      <p class="para_topic">The Solid Patch function creates a copy of the solid patch body in the cavity and core models on layer 25. Where appropriate, you can unite the solid patch body to the core or cavity body. In some cases, it's preferable to use the patch body as an insert rather than unite it to the cavity or core insert.</p>
