## Parasolid Bridge and iOS

On iOS, HOOPS Exchange is provided as a static library. The same occurs for the Parasolid Bridge which is available under a library file called libhepb.a. If the Parasolid Bridge is not used on iOS, its functions are replaced with placeholders which now have to be disabled using a specific macro definition.
