• When using the “Copy to 3dsMax” function in SketchUp, it will “export” what you are selecting to a new temporary SKP file (version 8 to ensure compatibility with everything) at the path “C:\Temp\”. You can hide this folder in windows if it annoys you, the script will still work normally. If the Temp folder is not deleted, you can “paste” it at any time, even after rebooting. Big thanks to TIG for the “export” method.
  • When using the “Paste from SketchUp” function in 3dsMax, it will import 3dsmax_temp.skp silently into 3dsMax with the last skp import setting.


  • You must have the script installed in both 3dsMax and SketchUp for it to work. It doesn’t matter which one you install first.
  • In SketchUp: use Extension Manager to install RBZ file. The “Copy to 3dsMax” command will appear in the Extensions menu.
  • In 3dsMax: drag and drop ms file into the viewport. You can find it in categories D95 DESIGN > Paste from SketchUp.


  • In SketchUp: Windows > Preferences > Shorcut > Copy to 3dsMax (Ctrl + Shift + C recommend).
  • In 3dsMax: Customize User Interface > Keyboard > D95 DESIGN > Paste from SketchUp (Ctrl + Shift + V recommend).

  • Fix some random crashes when use “Copy to 3dsMax” function.

This script is very simple to use, but there are 2 extremely important notes as follows.

  • Never go inside a group / component to “Copy to 3dsMax”, it will definitely make your SketchUp crash!
  • “Copy to 3dsMax” will be extremely slow (and may even crash) if SketchUp file is very heavy, consider opening another temporary SketchUp instance, paste in it (with normal copy-paste function), and then use the “Copy to 3dsMax”.
