Thanks for your answer TIG. I tested with the model and if the conversion does take long though. The problem I commented in the previous post I came up with a model downloaded earlier. I attached so that you can try. In that case, does not convert google sketchup and reports with an error message. In ruby console the message (sketchup :: group deprecated method).
In my final year project of computer science,run google sketchup from a program created by me. With some models perform well the conversion (a. Obj), but appears white screen error.. To what can this be? I need to check whether the execution was successful and that message makes the result may not be correct because the conversion has been performed and the error message has gone.
Thank you so much!
