Hello everyone, welcome back to PJ's CAD class. What we did last week was making
the prong and the basic shape of the ring, so let me turn on what we had last
time, and let me turn this off. Alright, so this is what we have left from last
time. Let's go to the ghost view.Today what we like to do is continue to build
the bead setting all the way around this ring shank. Let's get started.
For this engagement ring model part II, we would like to have the small stone for 1.2mm
How to make this stone you can look at my previous video
a right top corner with the info icon over there now you can find that video
or go to my channel, you will find the video for how to make a diamond. Alright
for easier for us to snap on a lot of things because this is a mesh.
and it's hard to snap on a lot of things, so I usually will do the command
it's called "mesh online" and for mesh online you click on any of the mesh and
hit ENTER, and it will give you the outline for exactly what you are looking from
the view. In this case, it's the top view. so I kind of give it some sort of around
its shape it's easier for us to snap on things
Next we are going to make those little beads what you can do is using the "pipe"
creating the curve and using the pipe on it. or you can use the cylinder in
fillet the edges. This time I am going to snapping into the end point
this is 1.2 mm so I'm going to use the radius for 0.25
which is diameter 0.5
and how long do you need it you definitely need it
you can have the bead long enough to get it into the ring shank, but not over the
ring shank. Alright, so we wanted this bead a little bit higher so your
jeweler were able to set it. You also don't want it to be too cutting into too
much. Alright, so let's go ahead to fillet edges on
this one. I'm going to use the "fillet edges". It's living right here, and then
let's choose 0.24 (mm). It's a little bit smaller than our diameter so it will
have a nice surface, and then let's image that we're going to have this
stone roughly about here. The best distance is you will have it about
0.1-0.15 mm. Okay, and then so what we are going to have
let's say if we have a stone right here, and our prong which is going to share
this it's going roughly about right there alright so that look nice to me.
What I'm going to do now is, if the prong look nice where whatever the position is
you're going to use that to mirror to the other side, and use that to mirror
to the bottom. Alright so the goal is.... we are going to do is having those
prongs.... let me group them temporary, and then we are going to almost setting more
like this way. and they will continue follow the ring shank so that's
the ideal we are going to do. So let's go
ahead then turn on the ring shank and let me move our stone to the side so
it's easier to see. Okay take a look on the perspective view. Alright so the
goal is... we need to have a stone place over there for the first one, and flow
along the curve, right? but we need to find the curve first, so we need to find
the center of this... the curve on the center of this surface,. The command
you're going to use under the "curve" you have "curve from the object" and you also
have the the one for "extract isocurve". Alright, it will pick up the surface
Right now you see this a line moving while my mouse is moving.
I want to snapping into the quadrant. if yours happen go in this direction, all
you need to do is go to the command bar right here, "toggle" you can toggle it
back to different direction , so I want to snap into the quadrant where
it's right in the middle. And the reason it doesn't go all the way to..... it doesn't
go all the way to the other sides because last week we split this ring
shank in half in order to get rid of the surface right there on the mide
part of the ring shank, so now we have the half of it. And all we need to do is
kind of mirror it to the other side. I gonna type in "0" and mirror there.
so once this mirror, I'm just going to join them.
let me turn them in to the other color so it is easier to see. So now that red
color curve is right there, so our goal is going to be....I no longer need that line.
Our goal is going to be a arrange this guy. we have to look at all three different
views. I'm holding the SHIFT (key) so they will turn in 90 degree and I'm gonna send
them right there. We kind of need to follow the curve so I'm going to make
them sit a little bit lower there. Alright, and then to do the flow
Alright one thing I haven't do is we need to make the cutter, but I just want
you to see how it goes before we actually go ahead and make the cutter
We need to make sure that is closed to the center. Alright so let's give a
try before we actually making the cutter
For easier modeling I usually in this in the scenario I will turn
on the "record history" and then we'll go into the "transform" and then we'll go
to "array" and you have "along the curve". Okay so the object you're going
to array is whole set Enter and then you hit this curve it will ask you how many
you want and I was trying for 23. Let's try it one more time.
So you have the stone flow all the way around and they kind of not line up
that's why you need to turn on the history because what you can do is you
can kind of move this up a little bit and then so let's take on the right view
so make sure they will aligned. so right after you get that you probably
don't need the very bottom one, so you can do is it's to delete that one.
So we know 23 will work so that will work on one side however if you
send this one it really depends on the size of the stone if you set on this one
sometimes you may happen is the stone is really dark. So usually we want
to punch a hole behind a stone. so we kind of need to make a cutter. so I'm
going to redo redo all the way back to the center. Alright, okay so how are we
going to make the cutter. (there are)two reasons you want to make a cutter. First,
It is going to make your stone looks brighter. Second reason, it is easier for the
stone setting so if you already pre make a seat
Alright, so we have this right here. I'm going to move it higher than my girdle
and I gonna holding.... I'm going to drag it and holding the CTRL (key) then you are
creating a surface there. Alright this is not a very good surface I
should do this way
okay we need to starting from this point let me go to the top because the line
that I draw if you zooming is actually a lot of points, and we want to reduce the
point for having a better model. so I'm going to do is to draw a circle, and our
diameter was 1.2 mm okay so I have that curve I'm going to
use that curve and bring it up a little bit over the girdle.
let's go to the perspective view I'm going to move this down with the Gumball
the blue arrow and then hold my CTRL (key) and you can see a ghost line there and
what it does is you are creating a surface. okay so let me do again I'm
going to move it down an arrow to somewhere it's just a little bit
below the girdle, and hold my CTRL (key) then I creating that surface. okay and
I'm also going to put a dot right at the center, and with that dot I want to
move it close to the bottom of my stone. So we are going to use the surface tool.
You have one is from extruded "from the curve to the point" so the curve we
want to extrude is the edge of that surface we just made, and you will go to snapping
to the point. Alright so now we have this one
and also this one. We are going to join them and also "cap" them so they will be
solid. I'm going to turn it into the red color. alright so this is a cutting tool
that is follow the bottom of the ring shank, I'm sorry bottom of the stone
and we're also going to make a cylinder snapping to the point as well the
cylinder is going to cut through the metal that is sitting on the top of it
usually you want to do is about 50% so I'm kind of eyeball like how big is it
and I want to make it longer, so I will have definitely have enough to go through
the ring shank. Now I'm going to do is boolean those "boolean unit" those
two. Alright so now this is the whole set that we are going to flow. Let
me move this one. We no longer need the curve. I'm just gonna delete it. Alright
so I'm going to group them and move it to move it you know on the side and turn
on my ring shank. Alright so let's go back to what we were doing almost, I
think this is exactly the same. Alright so we're gonna go into the front view
move this one here, coming here, coming here, alright. And let's take a look.... my
isocurve is disappeared, so let's do.... go to the "curve"- "curve from the object" and you
have "extract isocurve". I'm going to extract that one to make sure snapping
to the quadrant. You can extract one more time snapping to the quadrant that will
work too. And then pick up both curve and then you wanted to join them.
so we are going to use this one that's move it to almost the middle and
bring in a little bit that's enlarge this one and you want to
make sure that they follow the surface okay and then we're gonna use the same
command, turn on a history "record history"
I will go to "transform" and then you have "array" and then you have a "array along curve"
so let's start.... we already picked the object, and let's pick the path, we
were using 23 so we're gonna use 23 again. Alright so that's what I mean
that all the red parts, which is your cutting tool, will be longer than the
shank. Alright so let's move.... make sure that we have even number not even number
even looking on the shank. I'm gonna move this one just go up a little bit and
make sure that they align. Alright now on the very bottom one "ungroup" them we
don't need this one, we don't need this one, and we still need the rest of it.
okay now you're looking really good and that's don't forget to "ungroup" them. what
we need to do now is we need to trim them or "boolean difference" them so what I like
to do is to mirror all of them to the other side
okay and then we want to use the "boolean difference". Let's
"boolean difference" from the ring to all the red parts
let's do half first. if your computer is not super strong and you have so many
different small parts, it may crash. so let's do the boolean difference on one
side. It will say the boolean difference will break the history because we have
history, which is fine. Alright so now we have that one and then we are going
to boolean difference again with this
okay
Alright so now we have the stone on it and you also need to boolean the little
prongs to the ring shank. Let's take a look on the head let me delete this one.
Alright, so this is how we arrange the stone on it, and sometimes if it is
getting too closed you might need to move before you boolean you may need to move
them in a little bit on the top individually. Alright this is the
engagement ring with a six prong head and bead setting on the ring shank. I hope
you'll like it. Please like and comment and share my video that really helped me
ranking. It's really hard to continue without your support. Thank you very much
I will see you next Monday
