Using *.iges or *.x_t or *.step should work fine. It'll be saved as a dumb solid, but your version at school should have feature recognition and be able to (mostly) repopulate your feature tree.
Just to be a little more precise, any time you are going from one version of SOLIDWORKS to a previous one, you should ALWAYS use Parasolid format (x_t or x_b; the only difference is the first is a text format, the second is binary so the file will usually be smaller). The different versions of SOLIDWORKS use different versions of Parasolid so you may have to choose an earlier version than the latest listed in the export options dialog when exporting. Here is the help topic about Parasolid and how to get to the options:
The reasons to choose Parasolid over other formats are:
- It is the native format of SOLIDWORKS so the solids go directly out and back in without "translation" to and from another format which by its nature changes the data and then changes it back and therefore can introduce inaccuracies through the translation process.
- Parasolid will be faster because it does not have to translate into a different format and then back when importing. It also doesn't have to go through the process of "knitting" all of the faces together back into a solid. Parasolid translates the solids natively while the other formats translates them into surfaces and then back.
- Parasolid has better support for colors, assembly structure, and component names than many of the other formats.
I just wanted to add this detail to help you as well as anyone else encountering the thread in the future.
Thanks. I'll try it out next time I need to export something.
Tried out the .x_t file type and it looks a lot better than just a standard .stl. Thanks for the help
