I need to make about 400 selections to Subtract from a box using ProBoolean. Unfortunately it seems you have to select each individual one. Is there an easier way to do this? Essentially, I have a box and need about 400 holes punched through. I am just trying to determine the easiest way. Right now I have to click on each cylinder one by one after I have arrayed them in order to subtract them. Does ProBoolean have an option to select multiple objects at once to subtract?

Try attaching all the cylinders together first (convert 1 to an Editable Poly then attach the others to it).

True enough - gotta pick them all whichever way :)

If the holes have a regular pattern, I would suggest: make one “tile” (one hole with surround, 4 holes with surround, whatever the repeating pattern is). Do not include the “exterior side” faces (do include the hole sides), because then you want to make an array of tiles, attach the object, then weld the vertices. This will no doubt be MUCH cleaner than trying to boolean 400 holes.

If the holes are random… (shudder) it could be ugly.

I agree with all replies… here is some screenshots showing the process from start-to-finish.
In the example I am using 600 cylinders.

what is the purpose of this, would it not be easier to create a cutout map to achieve the same result or is this the hero geometry in the scene?
