Is there a way to import a model from SW 2018 that is optimalized in topology study into SW 2017?

Our school gives the licence to SW 2017, but not SW 2018. I have made a part in the 2018 trial and optimalized it in topology study. Now I want save and import this to SW 2017. Is this possible and what is the best way to do this? Thank you.
