What if I want to build a custom exporter, just like skp2xml but to export to my own custom format? There is out there any sort of tutorial? I have to use the SDK or (since I have a C dll library that is already able to create my structure, only needs the input model) I can use the Ruby API with

require; "custom.dll"

or something like that? Sorry if this reply is OT but I found no other way to contact Bugra.
