Hello, This is my second post in about 5 minutes. Sorry. Anyway, it's about something entirely different in MAX. Now, I will say that I absolutely hate Boolean, especially for MAX, but I have to use it now. My problem is, everytime I try to do Boolean [in this case, Subtraction (A-B)], it makes it so that it doesn't quite make all of the bottom lines and side lines of the subtracted object. In other words, it just makes it show through instead of having a side of the subtracted model. Get it? If you need a picture, please PM me or something like that. Patrick

Can you post a picture?

Sure, here it is...

Thanks!

Its possible the normals of the inside faces are flipped. Try reversing them.

Actually the problem is just that boolean sucks and you are entirely justified in hating it ;)

Here's a few tips for dealing with it:

1) Each individual boolean subtraction operation changes the geometry of the object, and the more complex and screwed up the geometry gets the more likely your next boolean is going to screw up. To avoid this, combine every boolean operation you need to do into one single object, and then subtract them all at once.

2) If the shape you cut out was pretty simple, you can reconstruct the missing faces by switching the the polygon selection mode, and clicking "Create". This will let you click on the vertex to remake the faces. Yes, it is tedious.

3) A faster way to do #2, in cases like the picture you showed, would be to:
duplicate the object you substracted, in the same place you did the subtraction
invert it's normals (flip all the faces) and delete the front and back sides (so you can see through it as intended)
scale it so it fits into the gap
combine everything into one mesh, select all the vertexes and weld them together
