Adjust Spread (between objects)

If you want to increase or reduce the distance between objects.


Usage
  • select several objects
  • run script
  • adjust slider amount
    • values greater than 0 increase spread
    • values less than 0 reduce spread (bunching objects)
  • close dialogue
Limitations
  • Does not take kindly to you changing the selection while the dialogue is still open
  • Does not count as an "undo step" (but setting adjust to 0 puts them back where you started)
Updates
  • introduced axis choice (X, Y, Z, X and Y or All)
  • added an undo point on running the script
  • introduced selection lock and other measures to reduce chance of "user error"
