larchitect No need to prepare it. I don't need textures etc. RN data is inside 3dm file, so i should be able to recreate it without issues. If 3dm won't be enough after first investigation I'll let you know what else do I need. Besides that if you ask me where to drop it I think wetransfer is best option, short period being online, big files allowed, direct link, no troubles easy peasy for any user to use.
