Limit Passes of Stock Spiral

One way to reduce the air motion is by limiting the stock spiral motion only to layers with fewer than a specific numbers of lanes.
If the number of lanes is greater than this value, a spiral pocket strategy (inside-out or outside-in) will be used.

1. Rerun the procedure.

   1. Mark the Strategy: Outside In option.

   2. Mark the Limit Passes of Stock Spiral option.

   3. Change the number of passes to 10.

      • If the number of passes is more than 10, a spiral pocket will be used.

      • If the number of passes is less than 10, a stock spiral will be used.

   

2. Save and calculate.
   Note that because this lane contains more than 10 passes, a spiral pocket is used.

   

3. Rerun the procedure and change the Z-Bottom to -80.
   

4. Save and calculate.

5. Use the Navigator to view the last layer.
   Note that because there are less than 10 passes in this layer, the stock spiral strategy is used.
