Hi. I've over zealously purged a window family and deleted the Default Sill Height property, so am unable to set the default height for new instances.... I've tried recreating the parameter in the family editor, but it doesn't recreate the original behaviour for new windows... how do you recreate it...??

More importantly, why is it possible to delete it? surely is should be like the other 'type' properties height, width, rough height, and rough width and not possible to delete it!!?

Thanks. Brad
