welcome to lesson three of the blender

jewelry design course again we're

working with blender 4.2 long-term

service or LTS version and today I'm

going to cover in lesson three is

learning how to work in three dimensions

and I have to admit this is going to be

one of the most difficult things for you

to understand some of you are going to

get it right away some of you are going

to take a much more longer time to

getting used to working in three

dimensions if you're not used to working

in CAD and working in a

three-dimensional environment you may

have a very difficult time understanding

um when you move objects from one

location to another where they end up in

the 3D space or the 3D World so I'm

going to get you started here and then I

want you to go play as much as you can

it took me um probably about an hour to

get used to working in three dimensions

so I don't expect the fact that you know

everybody's different everybody learns

differently so you know there's 8

billion people in this world and there's

probably four billion ways to teach

somebody something go ahead get started

follow along and then go play like I T

like I'm going to teach you in this

lesson to add some objects and move them

around get used to where they go and how

they kind of fit into the 3D

viewports let's get

started okay so one of the hardest

things to learn when you're starting to

use blender is learning how to work in

three dimensions three dimensions can be

quite confusing to people now if you

remember correctly in lesson one I

talked about this small little red and

white circle in it's in the middle of

the screen and that is directly in I'm

going to hide the cube here and you can

see that's directly in the intersections

of the X and Y axises denoted by the

green and red line so no matter how I

move here you can see that little Center

is in the center of the intersections of

the X and Y axises and that is the

center of your view space let's get that

Cube back

okay so now with that

selected you have to understand about

Origins now if I take this Cube and we

look at this Cube and I rotate around if

you remember correctly I told you in

lesson one using the middle Mouse button

we can rotate around a selected object

if you look very closely in the center

of this object you'll see a yellow

dot that yellow dot represents the

origin or center point of this Cube

that dot right now is on the origin of

our 3D view space which is denoted by

the red and white line or red and white

circle if I move this over with the

arrow key here and if you remember we

activated that by going to the gizmos

Tab and activating the move function

putting a check mark there we can now

move our object left and right forward

and back or up and down okay and if you

ever want to put that back hit shift s

and then we can go shift s and select

selection to cursor and that'll bring it

back to the

middle what I'm trying to get to is that

working in three dimensions is kind of

tricky in blender because we can use the

arrow keys to move them along the

accesses and if we want to go backwards

to control Z or command Z depending on

your keyboard and it'll undo that

previous move or you can press the G key

to move things around now let's take a

look at what I meant if I I'm going to

duplicate this object by pressing shift

d and pressing enter and now I have two

cubes so here's our first Cube here's

our second Cube now they're over each

other so really you really can't tell

which one I have selected I'll come to

my outliner here and I'll select Cube

001 which is the cube I just duplicated

and I'm going to move that over with the

yellow arrow so I'm basically moving it

along the y axis all the way over

over or behind this particular cube in a

straight line and by doing that I've

basically kept its origin along the

plane this grid is our plane and I I've

just moved it over and it's still lined

up in jewelry design we have to keep

things lined up you can take a cube and

let's just put this one

back you can take a cube and let's say

I'm looking looking at it from this

perspective and if I hit G and I move it

if I just move it over here you can see

now that it's

not it's not in line with the original

Cube this is this being the original

Cube this being the duplicate it's off

the plane it's raised up because I moved

it just freely and using the G key you

can freely move an object anywhere you

want but it pulls it out of alignment so

just keep that in mind you might run

into situations where you grab an object

using the G key to move it and move it

somewhere and now it's way off to the

side and you can't figure out how to put

it back well don't fret because we can

always put it back to the center and get

things

reoriented when working in CAD in

general you're always going to be

working with perspective views we're

going to look from uh on the keypad

we'll be pressing the one button okay

and if I put my mouse here and press one

on the keypad this is the front view the

Seven View is a top down View and three

is the side

view now that may seem kind of funky to

you right now but don't worry don't fret

too much for instance I can press

negative Y and it's a front view of my

scene just like pressing one on the

keypad if I want to look at this from

the opposite side I can press the nine

and that'll flip me 180 Dees along that

view if I don't make sense really what I

want you to do is go ahead and play so

you can see see what happens when you do

certain things if I look at this from

the side with the three key on my keypad

now I'm looking at from let's say a

negative an exposition or a negative

Exposition and I can flip it with these

buttons here if I don't have a keypad or

I can press three on my keypad to get

the side view and then the opposite side

would be pressing nine it basically just

rotates it along that same axis 180

degrees again with the Top If I look top

down so I'm looking this from the

positive Z looking down at something I

can press nine now and look at it from

the bottom eventually that will make

sense to you but it's it's going to take

a little

time when modeling a cad you don't ever

want to free form move your object

because freely moving an object puts it

in a weird spot and what happens if you

move it someplace and now you don't know

how to get it back there's a panic and

now I've got this thing that I can't

align right with with what I'm doing and

you'll notice this as you go further

plane that uh you can get things out of

whack so for instance if I look at this

now you can see this Cube even though it

looks very similar along the uh the red

mark or the x-axis it's below that its

Center Point now is below that that line

that red line so we can manually move it

up and do it that way and try to get it

lined up and sometimes that works and if

I go to three and then nine you can see

we're not lined up with the Z axis so I

can take the Y arrow and I can move it

over just like so and then go back to

one and now I have to move it over to

the center so that's the hard way of

doing

it

and that makes life really complicated

you're going to get frustrated so try

not to do that but if you do that if you

grab it with G and you just freely move

it now it's way off in the middle of

nowhere and it's not organized in the

way you think you want it to be select

that object and press shift s

and then the top selection which is

selection to cursor selection to cursor

means whatever object you have it's

origin point will be moved from here to

that red and white line or that red and

white circle so click that and boom it

puts it right back and now you can go

back and move it along any one of these

axises and try to keep it lined up

wherever you want

it there are times where you'll work

with free form or free moving but for

the most part I don't and and there's a

reason because most CAD programs um

you're either working with symmetrics or

you you need to have something that's

going to be moved right next to another

object so just get used to using these

red arrows to move things the Green

Arrow to move it along the Y and the

blue to move it along the z-axis just

keep that in

mind I'm just going to put that back for

now put it back in the center now we can

change the origin of an object for

instance let's get rid of this object

here so now we're back to our Cube and

it's the duplicate Cube but it doesn't

really matter and if I look at this from

the front view by pressing one on my

keypad now I'm looking at this also here

negative y so just keep that or positive

wise so just keep that in mind if I want

to look at it from the opposite view I

can just click that and flip back and

forth between views but I'm looking at

this from front view which is one on the

keypad and if I repeat myself I'm just

kind of beating it into you

with that done I can move my object up

just like so and I can say I want to

change the origin point of this object

and I want to put it at the 3D cursor

and that's kind of what you'll be doing

most in this jewry class well not mostly

but if we change the origin points

that's kind of what we do a lot and

you'll catch on as we move forward but I

can right click here come down to set

origin and 3D cursor and now you see

that little Green Dot is right in the

middle bottom of our Cube at the 3D

cursor which is that little red and

white circle for instance now if I come

over here and I just freely move this

thing and just put it way off in the

space where I don't want it if I press

shift s and I move the selection back to

the cursor we'll look at this from the

front view again now you see because we

changed the origin point of our Cube it

puts that object at its origin point in

the center position of the view 3D

viewport I hope that makes sense to you

working in three dimensions can ofly be

can be very difficult and for instance

I'm just going to give you a real quick

scenario of why I tend not to do that

let's say that I'm making um a name

plate and that name plate is going to

have diamonds on

it I'm going to take this Cube I'm going

to I'm going to shrink it down on the

z-axis and I'm going to expand it on the

Z or the x axis so SX and I'm going to

expand

it and now I've got this plate here now

I want to add diamonds to this plate and

to do that if we do it free form I can

come to jewelcraft and I'm going to go

into jewelcraft a lot more extensively

um in in one of the upcoming lessons I

believe it's going to be lesson six or

five but uh for now let's just go ahead

and add in a 1 mm diamond and you can

see that diamond gets added it always

gets added into the center point of our

3D viewport now I can take it by the

blue arrow and just kind of move it up

and put it right there and that's on

let's say this is our name plate it's

right on top of the name plate where a

diamond should sit well let's say I want

to move a diamond or I want to copy this

diamond and move it along that X line

right so if and this is why it's

important to use the arrows for X Y and

Z I'm going to take this and I'm going

to hit shift d to duplicate it press

enter and now I can just hit G to move

it and now I'm going to move it over

here and you can see what happens

because I'm I'm looking at this from a

weird angle it's putting

my my model in a weird position because

I may be moving this left and right but

left and right in the 3D world is

different when you're working

in a non-orthographic view

so let's get rid of this diamond because

we don't want it so what I typically do

is I'll hit seven to look at it from the

top and here's my

diamond

and I can hit shift duplicate and then

move it along the x axis so I'm going to

move it over here now we can't see it

unfortunately because it's buried but if

I use the arrow key you can see I'm

moving it along X and that's kind of

what I want you to get used to we're

going to duplicate that again and then

click and then I'm going to move it over

our new one just like so because if I

try to move it this way I don't know

where it's going to end up it could end

up anywhere like over here and now we

look at this from the front view you can

see the diamond's too high and we don't

want to waste time trying to get it all

oriented in in a

position that we waste time on so just

get familiar with that because it's

important to learn three dimensions and

what I suggest is

go ahead and play and I'm going to give

you a little lesson that I want you to

play with I'm going to go ahead and

delete

these um I use the X key to delete you

can also hit uh to add in a model we're

going to hit shift a we're going to come

over to mesh and I'm going to cover this

in a little more detail in one of the

upcoming lessons but we're going to go

ahead and add in a cube and there you

can see we go back to our items tab we

have another 2 mm dimensionally correct

Cube

and then I want you to add in another

object shift a we'll add in a oh let's

see about a UV

sphere and then what I want you to do is

play with these two just keeping them

lined up in a in a straight line like I

get like I said if we select the UV

sphere right here and I press G I'm

moving it all over the place right now

and it's freely moving in a free

location and it's not aligned in any

particular way of getting it

organized so I'm going to press contrl Z

and put that back and now let's take a

look if we move it from the front and I

hit

G I'm only moving it along the Z and the

x axis so it's still flat on our on our

plane if we look at it from I think it's

three you can see from the side view I

haven't moved off the blue line so

whatever

you're working on when you're working in

an orthographic mode you're you're going

to

see you have more control over where it

goes consider like

when if any of you ever took a drafting

class in school I when I was in high

school we had drafting classes you

always work with like a top view a side

view and a front view and you you always

made your objects conform to those three

views which is why it's important to use

a keypad with your computer when using

blender because I can go

front side and top and I can make sure

that I always Orient my

objects in the proper

way and I'm just going to put that back

over here and I'm doing this freely but

I'm I'm only working in two

Dimensions okay so now you see how that

works again go play because it's going

to be very important as we move through

and you're going to find that when I'm

teaching you how to make jewelry I'll be

showing you how to use the

arrows because it's going to be your

Lifeline to coordinating things in three

dimensions there's no real way to teach

you that other than to tell you to go

and play with this so be my guest after

you finish this lesson go Ahad and start

playing with three

dimensions now if you want to add more

objects to your screen remember shift a

you hold shift down and press the a key

brings up the add menu and if you don't

want to do that you can come over to the

add menu that's right here which is the

submenu in our 3D view Port I can come

down and I can add a mesh any one of

these things and I'll just go and add in

a cylinder and now if you see I'll just

move that over here and now you can see

we've got a cylinder we've got

a sphere and a cube and just play with

those get the feel for how to use the

arrows when you're selecting an object

for instance if I select the cylinder

now the cylinder has objects and I can

move it along y I can move it along Z

and if I rotate my screen a bit I can

move it along X you can do that with

every single object within your 3D

viewport so that's it for lesson three

again go get used to it spend about a

half an hour moving things around seeing

how they get messed up try using the

arrows to keep them located in a in a

much more organized and correct position

and then we're going to come back in

lesson in one of the lessons we start

making some jewelry designs with and

we're going to work more closely with

this that's it for lesson three I hope

you like this guys if you did please

give it a thumbs up if you have any

questions please put them in the

comments section below I'm going to try

to do a Q&A session so every time I get

a question in the comments I'm going to

make a small video to go through that

and cover the things within that lesson

itself thanks for watching have a great

day
