SigScribe4 version 1.1 is free.

Because SigScribe4 is primarily a tool for designing MODRATEC Lever Frame Kits, MODRATEC has decided to offer it free of charge to all. We do, however, require you to register your ownership of the product so that we can advise you of updates to SigScribe4. Please refer to the License Agreement for information about support for SigScribe4 users.
