An enhancement has been made to Pathfinder such that a warning message dialog will be displayed to the user if they enter a dimension of zero for an open hem feature in the graphical profile editor. Users might think that entering a dimension of zero will cause the feature to become a closed hem, but this is not the case. An open hem with a dimension of zero is not equivalent to a closed hem. The warning prompts the user to replace the open hem feature with a closed hem feature if they intend to create a fully smashed hem.
