Editing 3D Models with Meshmixer

This guide will teach basic editing of 3D models using Meshmixer.

Importing Files

Import an .stl or .obj file into Meshmixer.

  • Open Meshmixer
  • Click the Import box
  • Choose your file and click Open, or drag and drop your file into an open Meshmixer window


If you already have a file open in Meshmixer you can drag more files into the window. The program will ask if you want to Replace or Append. Choose Replace if you want to replace the old file with the new, or Append if you want to add the new file to the old.

You can also load multiple files into the program at a time by highlighting both.
