      <p class="para_topic">Follow Part creates a cut pattern by forming an equal number of offsets (where possible) from all specified Part geometry. Unlike Follow Periphery which offsets only from the peripheral loop (defined by Part or Blank geometry), Follow Part creates the cut pattern by offsetting from all Part geometry whether it defines the peripheral loop, islands, or cavities. It therefore guarantees the tool will cut along all Part geometry and eliminates the need for an Island Cleanup Pass. Follow Part offsets from Blank geometry only when there is no defined Part geometry to offset from (as in the case of facing regions). Part geometry defining cavities and islands is offset as illustrated below to create a Follow Part cut pattern.</p>

For these areas, the processor will generate additional cleanup moves to remove the material.</p>

      <p class="para_topic">We recommend that you use Follow Part for cavity regions with islands. This will eliminate the need to use Follow Periphery with Island Cleanup. Follow Part will ensure that all Part geometry will be cut completely without setting any toggles.</p>
      <p class="para_topic">The system attempts to create an equal number of offsets from all Part geometry. Intersecting offsets do not cross, but trim to one another as illustrated below.</p>

      <div class="title_figure">Maintaining Climb Cuts</div>
      <p class="para_topic">Unlike Follow Periphery, Follow Part does not allow you to specify a Pocket Direction of Inward or Outward. Instead, the system determines the Pocket Direction (stepover direction) as always cutting toward the Part geometry. In other words, for each set of offsets, the offset closest to the Part geometry is the last cutting pass. For cavities, the stepover direction is outward (cutting passes get continually larger as they progress toward the Part), while for islands the stepover direction is inward (cutting passes get continually smaller as they progress toward the Part).</p>
      <div class="title_division">Facing Regions</div>
      <p class="para_division">For facing regions (regions where the peripheral loop is defined by Blank geometry and there is no Part geometry), the offsets follow the peripheral shape defined by the Blank geometry and the stepover direction is inward.</p>

      <div class="title_division">Open Sided Regions</div>
      <p class="para_division">For open sided regions (regions where Part geometry offsets do not create a closed peripheral shape due to the intersection of Part and Blank geometry), the stepover direction is outward toward the Part geometry defining the periphery, and inward toward the Part geometry defining the islands.</p>

      <p class="para_division">For Planar and Cavity Milling operations with multiple cut levels, Follow Part evaluates the type of cut region at each level and applies the appropriate offsets.
