Welcome back to PJ Chen Design. Today I'm going to answer a question from
Ren Greenspan if I pronounced correct your name. It's interesting to looking at this
construction for this six-prong setting. so what we're gonna do today is kind of
discussed two ways to make this type of setting. Are you ready let's get started!
so I'm going to walk through my thinking process on this one with you when we get
this six-prong here one thing we can thinking about is to make each of the
u-shape and then we polar array, and then we'll call it done. the other way
that we're thinking about is we have a whole block and we kind of create
certain of a cutting tool, and to cut out the shape like this.
so I gonna show you both ways, and see whichever way that you will like it.
First of all, we will bring in the stone, and if you wanted to know how to make the
stone you can look at this video right here. I show you step-by-step making the
stone with all the cuts there so if you're interested in check out this
video. once you have the stone, I bring the stone in whatever the size that you
want it to be. Mine happen to be roughly about 8 millimeters something a big
diamond there, and then I'm going to making the surface that go around it so
I'm going to use this command, and then we are going to set it up to the zero.
depends on how high you want it. I usually will like to have my prong
longer than the table, so that way I will have the prong enough to bend over
so I want to have something like this, and if this is like too tall to you, not
like the picture there, maybe the girdle is way too high. We may want to scale one
detail and still moving up a little bit. okay so that will be the position that
we have. Thinking about you're going to offset inside or outside, you want to make
sure your prong is not cutting more than 20% of the prong thickness
by the stone, so that's what we wanted to look into it. Now we got that.
The second things we wanted to do is we need to make sure that it's evenly
spread it out for the six prong. so let's do the command going to be divided and
we're gonna divide this other edge for about six of them, so we want to make
sure the segment is six, and then we click okay. then we get those start there.
once we get those done, if you take a picture, if you take a detailed look on
this. those dots is representing the location on the top six-prong, and they
are coming down to the bottom, and the bottom is halfway of the six prong so
what we wanted to do is we're gonna pick up those top six point ctrl-c and ctrl-v
make duplication and scale them down like that small, I also notice they are
not completely aligned with the bigger circumference point there so what we
wanted to do is rotate it about thirty degrees, so that will be right in the
middle. I also wanted to move those down roughly somewhere like this okay
so now let me hide the stone, and let's just take the look on this, and I'm gonna
hide this one as well. As you can see we have those stuff on the outside those
stuff from inside and we need to draw a line that is definitely past those points.
So let's go ahead to use the curve tool. You got to curve tool right here
control point curve, and interpolate point. At this scenario, we want to make
sure we use interpolate point, and that will go through the point exactly
okay now let's take a look at the perspective. if I turn on my surface,
I could use that to pull back to the surface
but then when I need to have a thickness that won't be
accurate enough, so what I do to make it super accurate. I'm going to select this
one and project to the Cplane, and I want to delete the input so now they are
completely flat to the bottom. Next things I wanted to do is I want to
extended this curve, so let's going to the extended curve by line, and I'm just
needed to go straight, because I just needed to be over the edge there, and then
so we're gonna do the same thing on the other side. We want to extend it this one
and turn on the smart track, so we'll make sure that they come up the same
height. Now we have this. Let's go-ahead to rebuild it, so it will be more even. Let's
go-ahead to use seven point look nice let's click OK
We are going to make a copy of this to other layer, and then we might need to
use them later on. Let's just go ahead and hide that layer so one thing I
would like to do is I would like to offset this one, so first things is
offset your curve. I'm going to make my prong. it's about one millimeter so
offset on both side and for 0.5 millimeter each so
this is the new curve that I get. I always like to rebuild the curve and
make sure they are nice and smooth. alright so now we have this, we can pick
up those two, and use those two curves to trim the surface over there. so now you
can see we will have this surface over there. Let's turn on the stone and see
how that fit in there. okay so if that look all right to you, let's make into
the solid by offset the surface and we want them to coming outside and then we
want to make sure it is solid. so make sure that's not cutting too much of
a stone, and then roughly about 20%, so double check if they look
alright then we can have that using the polar array and we want to create in six
of them, for 360 degrees, and we can get something like this. If you like this one
that will be great. we'll just use this one, but I kind of noticed the top is
fitted perfectly because the curvature right here, you can see you have this
overlap in there. So they may not be super good this little things over
here is not a problem we can just make a cutter to cut it out later on in the
middle. That will not be the issue however that kind of overlapping there
is now what exactly I'm looking for. We can also take a look at the render view
right so the render view it actually looks fine, and if your jeweler can kind of
polish of that. That might be okay, but I just don't like that a little bit
overlapping over there. so I'm going to change another way to do it
the second way we are going to do is first I need to offset that piece coming
in for 0.5 millimeters. After that I'm going to rebuild this guy to make it
nice and rounded, and then I'm going to extend it to the curve by line. Make this
one just a little bit longer and we're gonna do the same thing on the other
side make sure you're smart track is on, and then you want to snapping here so
that will be the same height, and we want to close with the line let's go-ahead to
join all of them. so now this will be our cutter, before we make the cutter, we
want to offset this surface. let's go ahead to offset outside and solid equal YES
for one millimeter, and we are going to come in here extrude a planar curve- straight
So let's get something like this.
Let's do a simple test, we are going to pick up the extrusion, and we are going
to do polar array, six of them, Center is zero, type it six of them and see if that
is the shape that we want. so let's do the boolean and pick up this other shape
and also all the cutter so then you will have this cut it really nicely. Looking
at this surface right here if the surface is not what you want you might
need to alter the cutter a little bit so let's go-ahead to pick up the cutter and
just tilt it a little bit, and see if that comes out better. We can again
polar array, Center is zero, number for 360 for 6 of them and
that's what we get. Let's do boolean difference one more time, and let's see
if it is better. so you kind of see the angle right there
see if that is the curve you want you have a little bit extra there we can
just go ahead and delete those little pieces there. Once you get that
so once you get that we also need to cut the bottom design open there, so let's
go ahead to duplicate the edges, and it's happened to be the seam that we are
picking up, and then so we gotta make a cutter follow this, but we don't want to
cut it all the way to the top. it is somehow cut it somewhere in the middle of it.
Or just a little bit above the middle so let's go-ahead to split with the
the point on this one somewhere about right here, and that's they did this one okay
so now we have this curve
I wanted to pipe it over there if we pipe it just stop it right here, you're
going to see something like a rounded finish there, if that's what you want
that's fine, if not, let's go-ahead to use extended curve by line, and we want to
pick up this curve and want to go all the way up so it's continuing of it over
like that long. Next step we can use the the piping tool, we're gonna pipe it
something pretty big over here, and then we're gonna have something really small
over here, and that's hit enter, and see what we come up with. Now we have that
one that's through a test cut. Maybe I make the line way too long but
Boolean difference this one out of this one. and yes I kind of a cut it way too high
maybe I need to go back to make it shorter, but I'm just gonna, for this
the demonstration I'm going to using that one, so again we want to polar array six
of them 360 degrees, so all we need to do is boolean difference, and you can take a
look on the render view. As I say earlier I might cut it like too tall
you may not want to cut it that long, and this is for the printing file. That's why
I make the top it's like square, and things like that you need to leave
enough room for your jeweler to set the stone for you. I hope you enjoy the video
and I hope Ren, answer your question thank you everybody for watching check
