0301 Blender Using Boolean Setup Video Lecture | Learn 3D Modelling: The Ultimate Blender Guide - Software Development

all right in today's lesson we're going
to be looking at the boolean and how to
use it okay so to get started let's add
a mesh cylinder and let's say we decide
upon a size for the cylinder show me
let's see it and then the keyboard and
then we'll make this maybe 20 by 20 by 5
no let's go 3 ok
let's duplicate this it shift B on the
keyboard and let's make this one two
point five by two point five and by
let's say twenty perfect so we got this
thing right here let's jump in the top
it's seven in the keyboard Z let's just
make sure that this thing is in the
middle of the world so I'm lining it up
with the crosshairs the green and the
red and then I'm roughly gonna put this
one right about here
generally ruff I'm gonna pull in here
and here and here so I shift d and then
move it around all right well that looks
like a button hmm weird right let's make
a little bit of an impact on the button
so you know just like make it
interesting teach you a little bit more
so click on the button tab
face hold alt and shift at the same time
and you get in that ring just like
learned before
hit ctrl e right click that kind of
cancels the operation move when you
right click so it leaves it in a state
like this you never want to leave it all
the way like this because see these
faces right here those hidden faces can
lead to potential problems later on so
if you go like this you can now look at
shrink and flatten push and pull okay if
I push and pull I click on it and I
start moving the mouse down you can see
that what happens is yet it pulls it out
but it also gives it a little bit of an
R
there you see it so now it's kind of a
concave plate
so right click click shrink and flatten
now mouths down this one allows you to
pull it out and keep the inside non
concave so that's the difference between
push and pull shrink it flat okay let's
shrink and flatten it to about right
here
let's also hold shift and alt ctrl E and
let's move this up a little bit so we're
making this little Ridge let's do that
again shift and alt ctrl e shrink and
flatten
cool so now it's got this little Ridge
that we put in there that's interesting
enough to you know kind of do something
how about ctrl R click and then we'll
push this down just a little bit we'll
do the same with this one ctrl R push
that down so now we have this alright
now how abou lien works is we're gonna
take these and we're gonna kind of like
cut away at the surface using these now
this is not very good for geometry for a
game okay you would only probably use
this for you know things that are non
textured items so if you went to try to
texturize this button with a boolean
that have got it's really hard to align
the faces so anything that's a non
textured 3d model boolean's are great
for that in my humble opinion alright so
go to the next video I'll show you how
to use boolean
