Quote - Kerky don't seem to have any documentation about the file format, so I will have to analyze that anyway. The SketchUp script will help there, I suppose.

I'm sure if you ask on the kerky forum you'll get whatever info you need. The lack of documentation is most likely because of the small scale of the kerky operation, until recently it was just Giannis on his own (and in his free time) with a handful of testers. I remember Giannis saying once that if he had to write a manual he'd have to stop developing the code. Of course the users agreed that he should keep working on updates.

I believe that more recently other volunteers have joined him to develop particular aspects of the application and things like documentation.  I'm sure there are guys there who know enough about the file format to fill you in.
