do i have to search in registry?
Are you trying to change those parameters while creating the feature or just reset the defaults? If this is the first one I'm afraid the API function is missing. You can try to find these parameters in the registry (not quite sure that they are there) but even if you find them they will only take place after restarting of SolidWorks.
