After using proxy to reduce the file size, is that possible for us to turn the bounaing box back to actual models?
For some competitions they require skp model. I think it is a bit problematic if we submit a model with only bounding boxes inside...
Thanks for any suggestion.
You can do this already.
Select the component in SketchUp's 'Components' tray and go to the 'Edit' tab. Under the 'Loaded From' section click on the icon to re-load the .skp proxy that you would've created with Enscape. To convert back to a proxy you can just Enscape to overwrite the existing file.
