How to export skull (Only) as OBJ file

Hi, I downloaded the sample PreDentalSurgury CBCT file set and I need to export the skull as .OBJ file.

Please help me and mention what steps need to perform to do this task.

  • Go to the Segment Editor.
  • Click on “Add”.
  • Click on the “Threshold icon”, and adjust the values to encompass the bone (I used “700” as the low end)
  • Click Apply
  • Click on “Show 3D”
  • If the model that shows up looks good, Click on the tiny downward pointing triangle next to the green arrow icon and choose “Export to files”
