I have a machine built on a model and i want to take to a new model when i copy and then paste it to the new model a lot of parts are missing , how i can save built machines and then use it in new model? also if i want to size up or down a machine with many components how can i do it in one time without having to deal with each components a lone? also, there are some bin items that were build in an old model like pill bottle without a cap when i open a model it does not show it also when i copy its 3D code it just create a box so how can i also import these without the need of building them from scratch?
