[Question]change the location Model

After that, I can call the model from SD Card, then I have a question, is that:

  1. the Model run from the SD Card when the finger touches the screen, change the position to the Model that we have defined it?
  2. If the Model contains several sections, such as structures, buildings, etc. When called from an SD Card when you select menu, show room. It can give the room a split from Model.
