All language subtitles for [English (auto-generated)] Rope Chain 3D Modeling with Rhino 3D Jewelry CAD Design Tutorial #364 [DownSub.com]

welcome back to PJ train Design This is

PJ today I would like to share with you

how to use the jump ring to make a

simple rope chain and that will serve a

better rendering for your jewelry

presentation are you ready let's get

started

[Applause]

before we started I wanted to make sure

that this type of the 3D model is

intending for rendering most of the

chain is machine made and for casting

purpose it's not really necessary so

this is intending for rendering purpose

as starting from a scratch so I want to

come into my top view and draw ellipse

and roughly about this size right here

you can make it thicker or you can make

it thinner it's up to you and after that

I'm going to draw a circle this circle

could be any size that you want I'm

going to snapping into the quadrant now

you do not want it to have it way too

thick because it may not flow in nicely

so we wanted to have something is

reasonable so we're gonna stay with

something about 0.8 millimeter roughly

like there all right let's give it a try

by making the sweep one rail and I also

wanted to record a history just in case

this is too big to too small as

selecting the rail here and also

selecting the cross section so then we

will get our first link all right once

you have first link we kind of need to

know that if this is going to fitting

all of them so let's do a test right

here let me go ahead to hiding the curve

so we are going to moving this one to

this one and of course this one going to

end up with 90 degrees so I'm just go

ahead to rotate it right and the way the

Rope change to work is you have another

chain in between and this the link is

actually

rotate it into 45 degrees so I'm just

going to type it 45 right here right so

each of the link is linking into two

link right so let me change this one

into the green one and change this one

into the red one so it's easier for us

to see how things work all right so the

next set if this is happening correctly

let's take a look on the top view we

want a green one next to the green one

and so we'll get something like this

right but we want to make sure everybody

else is not touching notice that this 2

is actually jamming into the red one so

I actually need to moving this two back

a little bit somewhere like this so it's

not jamming into the red one right so

nobody is jamming into each other so

let's go ahead to delete those that's

just for the reference now we know those

three set is working so we're gonna

using the command for linear array and

we're going to say just do a testing for

five and we are going to snapping

holding our shift green one next to the

green one so we'll get something like

this right so this will be the link

structure now let's take a look on the

render View and see if you like it right

if you feel like this is like not enough

you actually wanted to have additional

so it doesn't look so loose in between

we're gonna come back here again let's

come back to the original Three and we

want to make additional one so let's go

ahead to making a copy Ctrl C Ctrl V and

I want to rotate this one for 90 degree

right there all right so you can see now

we have this new one is actually

overlapping with this one so we're gonna

moving this one coming over here all

right so every link that we have they

all need to linking with the two link so

that's the key of it right so that's

giving a try and we want a green one

to set it right here

and then so they will be linking

together I mean you can adjust a little

bit look like the red one need to be

going to the left a little bit small

even so it's not jamming into each other

this one and this one might need to move

into the left a little bit and then so

we'll get something like this all right

double make sure on the render view they

look nice they are not like jamming into

each other and if that were for you then

we are going to go ahead to delete those

and then we just want a grouping all of

those all right so let's give it a try

we want to use the linear array and

we're gonna pick up all of this and

let's say we're gonna do five set and

then we're gonna move in somewhere about

here

and take a look on that if that worked

well for you okay so now if we want to

apply it to a curve let's say I have a

curve so I go like this way

we're gonna give you the first try for

array along the curve and then we're

gonna get this one right here and let's

see what happened coming into the

transform we're gonna use array a long

curve

and when you array along the curve and

the base point we're gonna pick up here

and depends on how many you're going to

have let's say I have 20 of them and

it's still like jamming into each other

so I may change into like 14 of them and

see how that works you kind of need to

guess in the distance you can do that as

well so maybe I need to have less like

20 like 12 of them all right so it look

much better and then we'll take a look

on all of them notice that they are kind

of a tilted in a really weird way and

that's because we have the orientation

for free foam let's try roll like and

see if this is any difference it doesn't

make any difference but you also don't

want to use no rotation because that

will be like that so the best bet that

we have is a free form okay so I'm going

to click it here and we are just going

to moving all of this to the other

places so let me move the a curve down

and move everybody up a little bit all

right this is array a long curve that we

have here but it gives us some misline

alignment right there one thing you can

also try is before you actually flow or

array anything you want to ungroup them

and see if that gonna go better so we're

gonna pick up all of them again we're

gonna come into the array a long curve

and the base point is going to be here

and notice that it's doing the same

thing right and you're changing the

either with the row like or you're

changing the orientation is the same

thing so this is actually not gonna work

for us because we have to use four of

them as a set right so I'm going to try

another way right here so I'm gonna

having this one and let's find out how

long is it so we're gonna try length at

76.365 so I'm gonna make a copy and make

a apply straight with the polyline and

I'm going to using exactly the same

length all right so now I'm going to

just pick up those bring right here

right in the middle so I do making a

copy and that can actually fitting all

of them so I kind of need maybe just two

more set

and bring out right there

all right maybe just one set that will

work all right so now we have this right

here instead of using array we want to

use a flow so let's go to the transform

you have flow along curve it's going to

ask you the object we're going to pick

up everybody right here beside this

curve right here okay and Richard right

here we want to click yes because we do

not want it to be deformed and we want

to click on this space and also click on

this target all right so you will see it

flow much better and without twisting or

deform our wire so the first method is

using array a long curve if you have a

single chain that's not complicated and

it's just a jump ring hooking each other

array a long curve usually work in this

case we need to make sure you flow

nicely without having this kind of

accident all the chains going to the

right direction then we will use flow

along curve if they are interesting in

more of the clasp design I do have a

course specific design for it I have 11

different kind of clasp for you to use

and to download to use I hope you

enjoyed this video please like and

comment and let me know what you think

about it thank you for watching and I

will see you next
