Welcome back to PJ Chen Design. today we are going to look into this
intertwined style of pendant. Are you ready? let's get started!

people to learn jewelry design and providing free video here for you. I'm
going to starting at the front view bringing in the stone for about five
millimeters, and we are planning to do a prong set. so I'm going to draw a line
roughly about this, you do want to have your prong longer than the table. it
really depends on if you are using for the rendering or you are using for the 3d
printing. for the 3d printing you definitely want to have this a little
bit longer, so in my demonstration here I'm using for the rendering, so I want to
make it a little bit shorter most like when they finished. first things we
wanted to do is we want to pipe this guy. I want to make sure that the pipe that I
have. after piping I'm moving my prong in a little bit you don't want to cut more
than 25% of the prong thickness. you can make it bigger if you feel like this is
too thin there, but just make sure that it's not cutting more than 25%. after
that deciding how many prongs that you need to have. you can have polar array
and starting from the center as a zero, number of the piece you want a copy is
4, and we want to do 360 degree, so we get something like that.
that would be your prong, and then the second thing we wanted to do is we need
to create a bezel underneath it. so let me draw a curve a square almost like
this one, and I'm going to change to this color in blue, so I'm going to
tilt it a little bit. you do not want to this Square to be
over the stone size from the front view. you won't see the metal behind it.
let's go ahead to using the surface tool.
we want to use a revolve and set it as a
center zero, and we wanted to do 360 degree, and that's how we get the cup
underneath it. I might want to move it down a little bit more for look like
when it's done by the rendering. Let's go-ahead to
boolean union those four pieces, and let's go ahead and draw another box right
there, and roughly we want to move it to where pass the culet, and then we can do
boolean difference this one out of this one. so that's how we get the middle
piece now. let's go-ahead to do the intertwine pattern behind it, so we have
this stone. it's about five millimeters with the prong set I'm going to starting
with the circle at the front view, and you want to get it as close as possible
it really depends on the thickness in the back of that design, and we simply
wanted to use that and as the reference then we are coming into the curve tool
you have this one it's called helix, and for the helix if you are just not using
anything in the option. All you get is this spring looking things, but we want
to actually do additional things with this helix option. so let's go to the
helix and then we choose around the curve. it's going to ask you which curve you want to
pick, and I want to pick up this one now in my design I have them going around
for six turn, you can set it for three, four, five, six whatever that your design
is going to look like. I'm going to stick with six, so let me turn this curve into
the red color. once you see this, we're going to see this curve on the red color
is actually wrapping around to the purple color, and that's what we exactly
looking for. let's do a test. we are going to pick
up this red color, and we're going to use the pipe command. and simply just giving
roughly about diameter in one millimeter and take a look at how it looks.
and it's cutting the prong a little bit that's alright because we are going to
move it down later on and just take a look if that is the size you wanted to
to have. if not, you may want to make it bigger or make a smaller size on your
pipe. the next step what we wanted to do is we need to make a copy. so let me just
using control-c and control-v to paste in there. so now we have to shapes in there
all the peak right here in between the peak is about sixty degrees. what I did is
360 divided divided by six, so I got sixty degree there. so in between that
will be 30 degrees. so what I wanted to do is pick up the surface and using the
gumball to turning 30 degree, and you will get this intertwine design over
there. let's move it down a little bit, and make sure that they are touching. if
they are not, you might want to scale it down. because if they are not
touching, or they just barely touch, you might not have a good casting. you can do
1d scale to make it up a little bit like this. so that will fit it better and
after that all you need to have is to creating a jump ring, and that can hook
on the bail that you are designed for. if you are interesting in stone setting 3d
model don't forget to check out the playlist for a bunch of a video on the
stone setting and my course for stone setting with Rhino. I hope you enjoyed
