I have had my work convert a solidworks model to STEP and I am not able to load it onto my 2020 11’’ Ipad Pro. The file is approximately 180 MB in size. Is the file simply too large, or is there something else I should try?

The app has a progress bar when attempting to load the file, but it appears not to be moving.

Hi, that’s quite big, but can you please try to import it using x\_t (Parasolid) fileformat? You should get much better results.
