I have just tried to do the "separate by loose parts" option and I think there might be too many objects to separate so blender just crashes. Is there anyway I can do this without it crashing?

Thanks, Dan

These are the blocks here ^ ^ ^ ^

  • $\begingroup$ no, they are literally just blocks and there are about 50-100 of them they had arrays, that's why there are so many. im trying to separate the arrays $\endgroup$ – Dan99Dan Apr 19 '14 at 22:26

    $\begingroup$ I just tried it on 1000 cubes, generated from 3 arrays. Applied the arrays then separate by loose parts it took a while but it did work. $\endgroup$ – David Apr 19 '14 at 22:35

If you are having troubles with doing this in one operation you may have better luck by breaking it into smaller pieces.

  1. In edit mode goto side view and Box select one or two levels. Press B to start box select mode.
  2. Press CtrlL to select vertices linked to what is selected, this ensures you keep each piece together.
  3. Press P and choose Selection to separate the selected portion into a new object.
  4. Repeat until you have separated the whole tower into smaller parts.

  5. Select one of these smaller objects and go into edit mode.

  6. Press P and choose by Loose Parts
  7. Repeat for each part created above.
