Hello,

I've gone through this boolean tutorial a dozen times with limited success. Sometimes, I can boolean an object (cutter) from another and sometimes it doesn't do anything. I am sure this is something simple but the totorial always leaves out a couple keystrokes.

So, say I make a ball, run a cylinder through it and want to use the cylinder as a cutter. In normal boolean, I leave ball in foreground, cutter in background, hit boolean and ...well...nothing. :)

Also, the tutorial always uses some keystroke for like what I would normally use CTRL A for "select all" in windows. In the same tutorial, the guy always does some quick click action to select all on the cutter object.

Thanks,

Eric

Box layer 1
Sphere layer 2 [cutter]
move sphere half way threw box.
box in fg [foreground], sphere in bg [background]
shift + b [for Boolean - subtract ]
then, shift + " , For select all, I always use point mode, then, m, for merge all points

then you are done..
there are few tricks here and there..

Jeffry,

Thanks. I have these. The boolean one is the one I've watched so many times but for some reason, it would only work once in a while. I think I have it figured out now.

Although, still trying to figure out how to make a hole with the object appearing solid. In other words, I take my ball and using a cylinder, I cut a hole right dead through the center. Instead of it appearing like a tunnel, it appears as two holes, one on either side. So essentially, I can peer inside the ball. Is there a way to just cut a hole so the it has walls going through as well?

Thanks,
Eric

Sure there is! Part of the trick is how you subtract the disk from your ball. And whenever you do boolean operations, don't assume that a simple "merge points" afterwards is enough. You should probably check to make sure that points that were supposed to be merged actually did so.

BTW, I cleaned up the edges of this hole with Rounder.

Hey Thanks!

That is nice looking. I haven't gotten too familiar yet with rounder. I need to do that. I toyed with it the other day, now I can't even remember where it IS. :)

If you do a Boolean subtract that is what should happen. Meaning that you should get a sphere with a 'tunnel' though it.

create a sphere in layer 1 and cylinder in layer 2 (in background)
67908

run Boolean subtract
67910

merge points (if you want)
67911

If you are still having problems you should post some pictures for us to see.
