 * I tried to use a .stp/.step file. The upload of the file and the creation of 
   the shortcode works but when I access then the page the viewer returns the following
   error:
 * Failed to import model. (Failed to load occt-import-js.)
 * The console shows that the viewer is not able to find that file “occt-import-
   js-worker.js”
 * Somehow for example .stl .glb is working fine.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-while-using-stp-step-files%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

   it to another format.
