hello everyone welcome back to PJ's K class today we would like to build is this really
common hello ring for engagement ring and its really popular what we need to do is
quite simple we will need the following commands first we're going to use the revolve and it will
help to build a cup underneath the stone then we will use the pipe tool to make the prong and
once we make one set of the small stone we'll use polar array and I recommend you record a
history so you can change the prong position finally we'll use the sweep one command to
make the ring shank let's get started before we stop your model they are two video I would
like to argue to take a look on it it is on my youtube channel at PJ chain design on the
YouTube and you will see this video is showing you a lot of terminology how to how to set the
stone and telling tell you like what part is what's done what is the proper way to
hold a stone and the other video is to how to build a diamond in Rhino 5 and this has
two part on it it's a two video for how to build a diamond and once you build a diamond
you can stretch it make it into your oval shape if you like so let's go back to the right now
first of all we have a strong in our model and in my case my is above five point five
millimeters then we draw and we want to make a cup underneath it so let me open another layer
let's use this layer for the setting so I will draw a square and I want it to be longer than
the qulet I am going to move it here underneath the stone but tilted a little bit so I'll cup
well be tapered one thing to pay attention you don't want this in this position because you're
going to see a lot of metal and that will make you store smaller so we want to roughly get it
as close as possible and if it is too long we can always you know trim you later so what I
do is I'm going to use the revolve come in and type is zero as my center point hold shift and
click on anywhere with that will be 90 degree and then I want to revolve 360 degree so I get the cup
there second we need to make a prompt and we need to know where is the prone position here so I'm
using this curve and my all snap as on as you can see snap on my end point I mean can light up from
you and I want to continue going up a little bit there alright so that would be my curve and I can
pipe this one and roughly about 0.8 millimeters so radius will be point four millimeter long if
it's really about a propulsion if you feel like this is a little bit too small you can make it
bigger but the key is you don't want to prom to be overwhelming because that will make the zone
smaller okay so now I need to move my prawn just a little bit lower in the right position okay all I
need to do now is to use the rotate and make sure copy equal YES on the command bar and snap to the
zero and I want to have four prong so one two three and four so I have four prawn there so we
are done for the first one and then we can rotate it by 45 degrees to be in the right position
okay let's make a copy of center stone ctrl-c and ctrl-v then we want to select everything
beside one of the stone and then we're going to hide it so now we only have this stone okay
let's go it down to I'm Italian scale it down to roughly about two millimeter and it really
depends on your design in my case is roughly two millimeter for this demonstration then
we're going to do exactly the same thing we just did so on the right view I'm going
to throw a rectangular and you need to be longer to cut in cut into inside of the Ring
and then we're going to use revolve this guy and do 360 degree and then so we have that cup
going to do the same thing we are going to have we're going to draw Booker a straight line and I
wanted this line to extend by follow the angles or what I do is I move it back here and then I
see the tab key and then moving up you'll see a white line and that way you will have a really
straight line and let's go ahead and type it so 0.3 millimeter in radius that's 0.6 millimeter in
diameter so that's one of it and then we are going to using the rotate and then I'm gonna Center is a
zero and copy equal yes and first it's 120 and the second is 240 so I will have three-prong
evenly and I'm going to again rotate Paula I'm going to turn on I'm going to move this guy down
a little bit and turn now while we were hiding so in this case I need to have this guy with a
180 degree and we want to get it first close as possible and of course we want to tell to
the angle it look more graceful in this way and moving in a little bit okay it look really nice
all we need to do now is to polar array the whole things so I'm going to go to the tab
view and then go into a transform a raise polar going to set the center to the zero and guessing
roughly about self of them just need to make sure that the stone is not touching stone like this if
it does we might need to move the original one down a little bit so let's do it again we want
to move it out a little bit okay and this time let's record history go to transform a
reign polar array those object Center is 0 12 so let's take a look on that it's better and I just
notice that I have double prong here so in fact we just need two prong instead of three so I want
to show you this so we want to go back and did it one of them and we'll do the same thing like
polar away oh and then we want to make sure our history record a history and let's do the polar
array select the object and Center is a zero twelve of them and now I don't have a repeating
prong but if you take a look on the prong the prong is kind of cutting it very like on both
sides so actually I need to have this prong moving up a little bit so I'm gonna move this
because we have a record history so every prom will move along with it so now is it better so
we have all this ready so what we can do is we can select all of them and then we want to do
bullying unit it will tell you you will break the history but it's okay because we no longer unique
history there so we will have a whole things ready now it's time to make the ring King I
just need a simple ring think so what I'm going to do is to draw rectangular turn on my oh snap
and then again this depends on the design this tutorial once again is I Boyd so I want to move
the Gumbel and I want to use the Move tool to move to the midpoint to the court and let me explore
this guy and it puts explored and did it one side and I want to make this ability curve there
alright then let me join them together and give them a little bit radius I say coin three so
they all look a lil be rounded okay so I have one here and I'm going to me roll to the other side
all right and on the top why we need to make a song little bit lower okay on the top I need
to have this profile going here so I'm going to round this round you and then I'm going to rotate
it from the center and you want to actually get into the model so that way this you can pulling
them together but if you look at the perspective it's a little bit too wide and you can change it
to make it the form a small interest so I'm going to make it more narrow so you will look
paper the same form is going to me roll to the other side so so we'll get there so let me just
hide as temporary so you will see what I'm doing so you see the line here the curve here and the
curve there let me turning into the right color so we'll see better all right so what we need to do
now is we are going to use the sweep so it's sweep one it's the rail and this is the cross-section
all right and I like to keep them all in the inside of the rain check and make sure they face
the same direction all right and we don't need to close this week and now remember this is on these
surface we need to cap this there and you can type to come in so cap and pick up your surface
and now they are 10 ok turn number we were hiding all we need to do now is to find our curve folder
inside the ring shank we go into the solid extra planet curve straight and I want to make sure it's
solid equal yes both I equal yes all right then we need to do is bowling difference the setting
will be cut it out by the cube remember whatever you want to keep clicking first on the bowling
difference then we just need to bullying unit those but if you're going to have to tone for
example this is going to be the yellow goal and the other one is wykel and then you just keep
them separately okay full rendering prefers all right that's what we have for the hollow ring
today and I hope you enjoyed and I will see you in my other video thank you for watching
you
