hey everybody Welcome to lesson four of

the jewelry design course for blender in

today's lesson we're going to talk a

little bit about curves and meshes and

just a brief overview of their

differences I just want you to get

familiar with them because those those

are the two things that I use during

this course to Design

jewelry keep in mind as you follow along

with this lesson that to switch Which

models that you want to work with you

have to be in object mode select the

model that you want and then press the

Tab Key to go into edit mode or use the

drop down but box in the upper right or

upper left corner to select which mode

you want to work in let's get

started okay so in this part of the

course in this lesson we're going to

start working with meshes and curves and

I want to teach you a little bit about

the differences between those two and

how to distinguish them within the

outliner here in our window setup so

let's talk about that but before first

before we do that first I want to uh

make a change to our user interface

so if you haven't already done it go to

file new general and you should end up

don't save we should end up with a

screen that looks similar to this and

this is the default settings that we've

already incorporated into blender 4.2

and what I want to do is make sure that

you're on this little circle here which

is called the viewport shading area and

we're in solid viewport uh mode with

that selected hit this little drop down

Box come over to random you're you're

going to click on that little random

button and what that does is it changes

every object that's added to your 3D

viewport in a different color or a

slightly different colors so you can

distinguish the difference between which

objects are which in addition to that

come back to this little drop down arrow

and just to make it a little easier

we're going to turn on cavity cavity

allows for this if you look closely at

this Cube here now with cavity turned on

we have this lighter color outline

around the edges of our Cube and that

just makes uh distinguishing model just

a little bit more easy with that done I

am going to go to file menu to come down

to defaults save setup and I am going to

overwrite so every time I open up

blender now I am going to get this

different color models when I add new

models or new meshes to my 3D viewport

along with this little outline here just

to help you distinguish between Which

object you're working with with that

done let's start talking about meshes

and curves so we already have a mesh

here we've got the cube

you can use the add menu to add items

and we have meshes here these are all

meshes and if you followed along in

lesson one and two we activated some

extra stuff extra stuff would be like

the rock generator uh the diamonds extra

beams Factory wall factory things like

that we will use some of these in the

future that's why I wanted you to turn

them on but under the meshes option the

submenu from add these are meshes curves

curves are the second option here and if

we go to Curves and we hold our Mouse

over that you can see we get all these

different curves there are a couple

different types of Curves used in

blender but for the most part we're

going to

use pretty much for everything we're

going to use either a path or a circle

so let's just understand that those are

the two that we'll be using for the

jewelry course it's very rare that we

use anything else but if we do I will go

with that into that in more

detail okay so here's our here's our our

mesh object and it is a cube I'm going

to move it over here just to get it out

of the way and I'm using the Green Arrow

just to move it along the Y

AIS I'm going to hit uh I'm going to

come over to the add menu again you can

come down to add or you can hit shift a

with your cursor in the 3D viewport and

we can select those same objects here so

I'm going to come down to curve and I'm

going to choose

Circle okay so here's our mesh let's

just move it a little bit closer to the

circle and here is our curve Circle

Circle and you can look closely at your

outliner here and in the outliner you

will see you have your Cube and your

bezier circle now if you look closely to

the little green marks next to those

those little icons you'll see this

little triangle which has

a set of three

lines connected to a set of three little

points or little squares that means that

this model is denoted by that little

icon to be a mesh so when we work with

that object we know that it's a mesh if

we click and highlight our Circle we

come over to the circle or the bzier

circle list in our outliner you can see

that we have two little dots with a

single line between them and that is the

denotation icon for an object being a

curve

object in addition to that we get some

we get several different option changes

here but for the most part this object

here which is the curve d data changes

when we click on our Cube then we get

the cube Mark here and that's the data

for our Cube we are going to get into

too much detail into this but I just

wanted you to understand that when you

have a mesh selected you will see a

triangle here when you have a circle

selected or curve you'll see the little

curve icon here and in addition to the

outliner you'll see both of those listed

there with that said we can go into edit

mode now there's two ways to go into

edit mode for some of you the tab key is

the switch between edit and object mode

object mode is the mode we're in right

now and it's denoted by this little line

here you can see it says object mode if

we select our mesh and we press the Tab

Key you notice we go into edit mode

noted by this little edit mode box here

ifot if you press the tab key it'll

switch back and forth when you do that

you're in edit mode you get little

options here on the T Bar if you don't

have that turned on press the T key and

it turns that on and

off and you can see that we have our

mesh object now highlighted in yellow

and that means that we've got the object

selected in edit mode now there are

three sub modes in mesh mode first we

have the vertices mode where we have

vertices selected when you have the

vertices selected here you'll see little

orange dots on the corners of our mesh

or at any any intersecting point between

lines

in addition to that we can switch modes

to the edge mode select and if we do

that you'll see that the lines are now

highlighted and we lose our little dots

in between but we can select a line just

like we could select an edge I'll come

over here and I'll show you in Edge mode

we can select just one Edge click on it

you can hold the shift key down and

select multiple vertices I apologize

those are vertices and if we switch to

Edge mode we can select multiple

edges okay

so the last mode and this is the one

we'll probably work in uh we'll probably

work in Edge mode select and face mode

select a lot when we're in edit mode if

we select this icon here which is face

mode in edit mode now we can select

faces just by clicking on them in

addition you can press a to select all

of them and if you press a

twice they'll go

away okay so

now if we grab our Cube and we want to

move it again we can move it with the

arrow keys we could freefor move it by

pressing and releasing the G key and

then moving our Mouse right click to

cancel that last step and you can left

click to apply that last step now that's

how we can denote I'm going to press all

to select all faces and again we're

going to go into vertex mode and you can

see we've got all these little dots

selected and that's the vertices of our

Cube so you can see they're all selected

now that's a mesh and we can make

changes to this mesh and I'm going to

encourage you to go and try this and

play with it I can go into edit mode

select the face mode icon click on this

face and now you can see with the arrows

I can adjust it any way I want so I can

move it around up and down think of mesh

mode as a bunch of pieces of paper or

cardboard that are stuck together at

the at the edges of them so for instance

if I let's just add in another object

and maybe this will help we're going to

go and add in a cylinder mesh cylinder

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

move this over this way and if we go

into edit mode and we see we go into

vertex mode you can see all the little

dots at all the intersecting points of

the lines we go into Edge mode now we

can select the

lines and if we go into face mode you

can see by selecting a face that like I

said it's like a piece of cardboard

that's cut and then stuck together with

objects next to it or other pieces of

cardboard to make an object

solid okay that's how meshes are

made and then we can go and make changes

to these we can go ahead and make our

own meshes which we'll get into in the

future let's take a look at the curves

so we'll go back to object mode so make

sure you're in object mode you can

either down or you could either drop

this down and select object mode or you

can press the Tab Key and make sure that

you go into object mode again look over

here I press the Tab Key we go into edit

mode press the Tab Key we go back into

object mode so that's your

toggle okay so let's select our bezier

curve now bezier curves are different in

that I want you to think of this

as um an object that is like a garden

hose where you have multiple points

along that garden hose that you can drag

rotate size up and down make changes to

so let's go into edit mode with that

selected and you'll see that we

have these little lines and dots that

correspond to

our curve now I'm going to look at this

from the top down so I'm going to press

seven and I'm going to grab this little

Point here and if I hit if I just move

this around you can see what it's doing

is it's applying changes to the curve to

conform and keep kind of a an

orientation of

not not a sharp orientation around this

curve object right it's it's allowing me

I can grab any one of these dots I can

keep and bend and it just kind of keeps

somewhat of a curvy form not a sharp

edge contrary to that if we go back into

object mode and select our cube right if

I select the cube I come into edit mode

and I'll grab the edge we're going to

grab this edge here if I go into seven

here look at it from the top down you

can see it it's it's basically bending

or or extending those sides those pieces

of cardboard to accommodate the

differences in that model okay so let's

just grab our beier curve again look at

it from the top and I can come over here

I can grab this whole thing here and I

can hit s and size this and you can see

what it does it I'm changing the

rotation and or this the adjust

adjusting the size and it's making

changes to the curve always keeping a

slight curvy form to the curve

object in addition to that I can go down

to my curve properties and I can make

changes here where I can for instance

let's come up to GE geometry here and if

I scroll down a little bit to where it

says bevel I can give this some depth

and make this look a little bit more

solid and that may help you understand

what a curve does so here's our ring

right let's say it's let's say it's a a

car key ring right and I can come into

edit mode and I can make changes here by

just adjusting the size I can rotate it

and make changes like this curves are

non-destructible objects that you can

turn into meshes when you're happy with

the outcome and then we can model with

those to make a 3D printed object in

this case we'll be making

jewelry so I want you to go ahead and

play with that and find the difference

between meshes and curve objects just go

ahead and play don't worry about

destroying anything or you can always

restart blender or go to file new and

create a new general project and add all

the objects again but get familiar with

those I'm not going to go into much more

detail in this particular lesson I just

wanted to get you started with the

differences here and we'll cover those

more in detail as we start modeling

objects thanks for watching I hope you

enjoyed this video if you did please

give it a thumbs up and of course this

is going to be part of a paid course so

while the first five videos of this

course are going to be free as we get

into more detail it is of course going

to be a paid uh course and bunch of

lessons I intend to have between 50 and

70 lessons here so let's keep moving
