      Hi,

      I'm working a project where I would like to get ruby drawing info using the Sketchup API and then translate that into a more reasonable data format (basically ADTs). So I would ideally have info about each major object (vaguely defined) such as a wall, a window, a ceiling, etc and where each component belongs and what is adjacent to each component. Then I would like to export this data to Java and optimize the amount of daylight in the room by moving the windows around. Then write the results back to sketchup to make a new drawing.

      Has anyone done anything like this before? It seems like a lot of work to build the data structures, but I can do something like

      for ent in Sketchup.active_model.active_entities and then check
      ent.is_a? Face (then check if it's opaque or not to see if it's a window)

      to build the data structures and the relationships between them.

      How should I go about exporting the data I gather? I could write it to a text file and then read the text file into Java. Or I could put it into a database. I haven't done any database programming, but ruby has a lot of database libraries.

      Any suggestions?

      Thanks.

        This is for a research project that I'm doing for school for the summer.

          We've had a hard time with scene parsing too. It seems that SU just doesn't know what it has in the scene very well. We've contacted Google and are still waiting for some sort of a response. I'm not all that familiar with the exact details behind our scene parsing process. Some of it is done in C++, the rest in Ruby. If you download the demo of V-Ray for SketchUp, there should be a file that it installs named "VRayForSketchUp.rb" that at least appears to have a good bit of scene parsing stuff in there. I hope it helps.

          Below is our cry for help to Google ::weeps:: no love.
