How to export components of each definition file (for import Lumion as nodes)?

[DanRathbun]

This coding problem usually requires that the model hierarchy be walked.

Ruby scene serialization

What tells you that there is something wrong? At the moment this code has little to do with serialization but rather with tree traversal. Do you have a specific question about traversing the SketchUp scene graph? What is your use case, do you want to export all types of entities or just specific ones (here you only consider groups)? So far I can only give some remarks: Put triple backticks ``` on the empty lines before and after your code in this forum to make the forum format it properly…

Retrieve position of face vertex in global frame of reference

Positions obtained from vertices are always locale to their parent - not global. In order to work out the global position you need the combined transformation for all the parent instances. How you do that depend on context of how your extension work. For instance, if your extension works on the active_entities at all time, then you can obtain the transformation via model.edit_transform. But if you are traversing the whole model, say if you do a model export, then you need to keep track of the…
