Blacksmith3D-Standard and Blacksmith3D-Pro This package contains the convertible demo for "Blacksmith3D". When unregistered, it contains all of the features of the full suite, with file saving/exporting disabled. When you register a sub-product such as Blacksmith3D-Standard or Blacksmith3D-Pro, the demo will convert to that product, allowing you to use it's features and save/export your work, while hiding the unregistered features. Thank you for previewing our software and we hope that you find it a powerful addition to your toolset! Dave
