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.

SigScribe4 comes with full documentation which includes both a simple and an advanced Tutorial to guide you through the design process. Any questions or difficulties can be posted on the 'Guest Lounge' forum for resolution. Email support is also available. If you are struggling with a design that you would like to turn into a working Lever Frame, please send us your SigScribe4 file (???.ss4) attached to an email and we will be happy to suggest a solution for you. Give as much detail as possible in your email about what you wish to achieve in your design.

You Need Java

SigScribe4 runs under Java and is packaged for both Windows and Mac. Many computers come with Java already installed. (Java is not the same as JavaScript used in web browsers.) Java is sometimes referred to as the Java Runtime Environment (JRE), and at other times as the Java Virtual Machine (JVM). All Mac OS-X machines have Java installed by default, as do many of the later Windows computers. You need to have at least Java 1.4 (e.g. 1.4.2) to support SigScribe4. If necessary, download Java from this website: www.java.com.

For Other Operating Systems

Please ask - we can almost certainly help.

REWARD

We like to give surprises! In January 2006, Chris of Coonabarabran, NSW, Australia, became the 500th person currently registered as a SigScribe4 user. We decided to reward him with a special Discount Voucher to use in the MODRATEC Shop.

And we did the same for Ali from Scotland when he became the 1000th registered SigScribe4 user in March 2007.

The surprises continue: SigScribe4 user 2000 - Damien of Taree, New South Wales, September 2009.
