Currently I have the student version of solidworks at home and it is the 2015-16 version. At school however we have the 2012-13 version of solidworks. Just saving a 2015 file as a regular part file makes it unable to open up in the older version that we have at the school. I tried using an .stl file type to transfer it to the one at school and it opened up, except it doesn't have an as smooth of a texture and looks kind of blocky in a way. Is there another file type that I can use across both versions without losing some detail in a part?
