0503 Blender Boolean example Video Lecture | Learn 3D Modelling: The Ultimate Blender Guide - Software Development

alright now we're going to make a little
base for this and we're going to do it
something maybe a little bit fun so
let's grab a cylinder or actually now
let's grab ya cylinder would be catechol
right let's go to cylinder okay what we
need to do is rotate the cylinder and
we'll rotate it so it's like this so
over here you have to lock down that
dimension to be or that rotation to be
90 degrees so that's an object mode and
we're going to make this a little bit
bigger a little bit longer but not too
much to take over the fact that the
letters are there so it's 7z and we'll
make this whole way sort of like this
all right now what we're going to do is
flatten out one side of the cylinder so
it can sit flat on a desk so tab I'm
going to grab all the vertices in the
top view like this and then we're going
to hit our own keyboard too and then
scale so r and then scale it to be flat
like this so all I'm doing is scaling to
one degree and it'll flatten out those /
z just like that perfect right
okay now go into three on the keyboard
or wherever the side view is Z and let's
align this so that this nifty little
thing is about like this now I don't
know if we need this much thickness as
far as the the tall is concerned maybe
something more like this would work so
I'm just going to scale this so I'm not
using a bunch of unneeded plastic this
is perfect this is exactly what I need
so what I need now is a trench in order
for these to be a little area at which I
can maybe snug this into that little
trench so i can print them as two
separate pieces okay well shorten this
up just a little bit because I want that
track to go all the way to the end and
then I'm going to jump into seven and
finite this by hitting Z to go into edit
mode and I'm just going to move this
right to the end almost right to the end
you can see right here that is not
exactly near the end but exactly very
close to the end same over here so I'm
leaving a little bit of room outside
that perfect okay now save your work
because sometimes this could I don't
know crash on you
perfect so I saved that as a blender
file okay always save before you do a
boolean always so in this case this is
going to be my pattern um i'm going to
call this cut okay and this is the thing
i need cut so i'll call this base okay
now with the base selected go to the
wrench drop it to boolean and choose
difference and then choose cut hit Z on
the keyboard and you'll see that there's
a trench here now trust me I made that
look easy so what I'm going to do is
actually show you something that could
happen so just I'm going to X this out
and I want to show you something that
might happen just make sure that when
you hit tab and then L to highlight all
your geometry all your letters show the
normals okay you do that by clicking
this button down below and then sighs
them if they're all sticking out like
this everything will be perfect if some
of them are not sticking out you should
hit recalculate normals and if they are
all the way inside the mesh you should
hit flip direction so all the mesh all
the normal should be pointing out and
that's why it works so easy so that's
how you repair it if it doesn't work
okay let's go back to it again base
boolean difference cut and this time I'm
going to hit apply alright so now i have
my text I have this little base it has a
groove in it that matches this I just
need to lay everything out flat for the
print okay and that's how you this is
how you do that I'm going to rotate the
peace and I'm going to make sure that i
rotated a perfect degree 180 degrees so
it should have 90 s 180s to 70s but
nothing as far as like 45 or 30 here
okay now you have two pieces of geometry
and I'm going to treat it as such as far
as the export is concerned so grab the
first piece of geometry in object mode
and just go file export I'm going to
export this to a specific location you
can use a thumb drive doesn't really
matter
I call this one base and this one I'm
just going to export that file export
and we're going to call this initials
okay in the next video I want to show
you a product that you'll need and or
web service so you can use to clean up
the geometry to make sure it's printable
