You can define the height of islands for 2.5 Axis features in two
directions.
In previous releases, SOLIDWORKS CAM
automatically specified island height from the topmost point of the island face to the
bottom of the feature. If the island face was a different height than the top face of
the feature, the resultant island was shorter compared to the feature height. You could
not increase the island height in the other direction to match the feature height.
In the 2.5 Axis
Feature: Island Entities PropertyManager, you can specify island height
under End condition - Direction 2. You can define
the height in Z+ and Z- directions. The direction associated with End
Condition - Direction 2 is opposite to the bottom profile of the island
feature.
