Sigasi Studio XPRT advanced features

Stop wasting time on outdated documentation! With the XPRT edition of Sigasi Studio all it takes is one push of a button and you will generate complete state machine diagrams and block diagrams. Something that normally can take up to 4 hours per drawing.

But there is more! Our premium Documentation Generator creates a HTML or PDF document with all the relevant information from your project. Information will not be duplicated, it is always consistent. Documentation is kept up-to-date automatically. Text for documentation can also be written as inline comments in the code.
