In my previous post I covered DPTPB Dynamic shape usage in manual mode. At the end of the previous post I described briefly how to add new disk sizes to existing front view shapes and promised to deliver more detailed and safer instructions for adding new disk sizes.
The method I described earlier is based on manually editing shapesheet variables in master shapesheet. While not awfully difficult, manually editing might sound scary to users unfamiliar with Visio shapesheets and variables. Additionally manual operations always carry more risks.
