Pendant Design in Rhino 6 (2018)-Jewelry CAD Design Tutorial #30

Posted by


Hello everyone welcome back to PJ Chen
Design channel. This channel is about sharing rhino3d knowledge to student and
3d model professionals learning various Rhino3d techniques. Today we would like to
talk about is making this pendant that has some design on the side. I would like
to talk about where you can get an idea for the design and also how to you build
this model. Are you ready let’s get started before we get starting our model. This is
a wonderful website I would like to share with you. It is called Stuller.com. It
is a wholesaler website that you have to have a wholesale license in order to
purchase from them. However, there are a lot of a good information on this website.
They are the largest wholesaler in the United States, so if you go into the
product they have all different product that you can take a look on it.
especially if you look at the ring. Let’s take a look on the ring. The good things
that I like is the image is really really big, and then they also….. most of
the image they will give you the top, front, side view. so if you go into anything
that you like, and you can click on any of them. and you can quickly to see they
have the 3/4 view, and the front view already. so that helped you to understand
what they look like in certain type of a design. especially when you have certain
type of a twist, sometimes it’s hard to know what the side view look like. so
this is a really good reference website for you. Even though you may not have a
license from them yet, but you will love the website. so what I’d like you to do
is go into the website and type it the 4 prongs pendant design, and you will
come up all those 4 prongs pendant design but the one I would like you to
take a look on it, is something like a little bit filigree style and
and a good thing is when you go in, you can kind of enlarge it, so if you want to
get a detail you can see all those really big image there, okay so there’s a
lot of the design you can kind of explore it with them, like this kind of
scroll type of a design and also give you a good idea what is the thickness
possible will look like. A lot of my subscribers, you guys are just starting
with a jewelry design and a lot of things about the casting, about a
thickness, about what is a end product should look like. This will be an
excellent website for you to explore okay so let’s go back to our Rhino,
and let’s take a look what we’re going to do today. I’m going to maybe make it
into the darker color so easier for you to see. Alright, so we are going to do a
four prong design. One thing that I would like to mention right here. This is the
prong on the twelve o’clock, six o’clock ,and three and nine ,and this is the arrangement
for pendant. A lot of time if you are doing a ring which is that the ring
shank is gonna go with the 9 o’clock to 3 o’clock. your prong probably need to
move it like 45 degree. What I mean is the prong won’t be oriented like this way
and it will most likely be oriented like 45 degrees almost like this way, okay. so
this is look nicer on the ring, because the prong is not gonna hit something
else and that’s very small detail but if you are in the jewelry design you
probably need to know this. So let’s go back to our topic today to make this
pendant. Alright so for this pendant we are not gonna making the chain you can
take a look on my other video, that actually show you how to make chain and
how to, you know, make chain for the rendering. So I’m going to delete this
guy right here and we’ll make this later so I’m going to hide this one as well
that’s just take a look on this. If you look at
this, before you actually start building all the parts, we have to look at
overall. You can see that this is if there’s no pattern at all it could be a
cup of looking things. so what we like to do is we will build the cup just the
shape of it, and we will actually make a UV curve and from there we’ll do the
design from there. Let’s start with a stone for any of the desired size you
want it so let’s go to the top view at the top view I’m going to draw a circle.
The first circle will be slightly smaller. This is where the bottom circle
will be, the second circle will be almost the same size of our stone. Okay and then
I’m looking at here my perspective (view) you see two circles. I’m going to move the
first circle down and we want to move it lower then the culet, which is the
tip of the stone on the bottom, because we want to make sure that any things
that we are working on after we set the stone the culet, which is this point
right here on my right view, it won’t stick it out so it won’t scratch any of
your skin. okay so I’m going to make this slightly smaller. and then I’m going to
creating a curve it’s going to snapping from this point to this point. To
creating the surface I’m going to go to the surface you have sweep2 and go to
rail1, rail2, and cross-section. You can make them puffier you’re almost
straight it’s really personal preference okay so with this we are going to create
a UV curve you can go to curve- curve from the object- and then you have create
UV curves. then let’s snapping on this surface and hit Enter. then you will come
up this box right here this box means that surface it’s completely flattened
out This is the area going to be. okay so I
need to have four prong and notice that the seam is on the 12 o’clock corner so
which means right here on the left side this is well be the seam so left to the
right those will be the same over there okay so I would like to do is to
breaking this full curve into 4 small curves, and then on the top and the
bottom I’m going to be typing “divide” and I want to divide it into four
sections, so that’s also tell me where the prong location will be. so easily I’m
going to put a curve from the point a point s,o that helped me to divided this
curve into four equal sections, and then so that’s where the prong is going to be
and then we want to design within this area. okay so let’s take a look what the
prong will look like. With this (stone) is about 7 millimeters I would like to set my
prong it’s about one point two millimeter so I’m going to my
rectangular and actually I like to use a conic corner, and I have explained this
in other video if you’re interesting why do I like it, you can check on those
video. so let’s go to the front view and then I’m going to type it 1.2
that’s for the length, and the other length is also going to be 1.2, and I’m just kind of moving with my mouse to see what is the shape
looked like. okay so this is where the area is going to have a prong, and I’m
going to just have this one and then copy another one up here, and the reason
I want to get it longer is because I need to have a prong longer so my
jeweler is able to set it, then I will have the command is called “loft” and I
go from here to there. Hit Entere so then you have the prong, and let’s go ahead
and cap it. so now it is solid. okay so we have one there. All we need to do now is
making a bunch of copies, and I wanna snapping into the end point. Let’s go
take a look on the perspective (view), and snapping to the end point of each of
them, so we know that we are designed within this area okay so now let’s go to
the top and let’s do our design. so our first design. it’s going to be some sort
of a shape…. I would like to actually put the point in the middle, so what I like to
do is I’m going to go to the perspective view, and then using the split command,
and pick up this one and then we want to split with this point, this point, and this
point. So we kind of split them into four equal sections. So that way we can
snapping into the middle. Okay let’s go back to the top view, and then we can do
our design right here. So the first one I can snapping into the middle, and I kind
of need to know how high they are going to be. The line right here on the
top, if you look back to our original one is almost just a little bit under the
girdle, right? So I don’t want my design over or reach the girdle. Actually I want
to be just a little bit lower than the girdle so I think that it’s a good
position right there. From there, I’m going to use my curve and snapping into
the endpoint, and kind of design some sort of leaf looking things, something
like this. Okay and I’m going to mirror that to the other side. Alright so
that’s my first leaf, and it’s really up to you. how you like them I actually like
them a little fat and so that will come up the better
casting quality. and I’m going to use my ellipse tool on the second one with the
diameter and I’m going snapping into the quadrant – quadrant, and you want to go into
the front view to do it. Kind of using the prong to give me a good idea of how
thick they should look like Alright so now this is my one of the
profile I’m going to make another profile with the same command going from
here to here, and again, we won’t go to the front view and we want to go
something it’s a little bit thin there to start with.
Okay so now what we can do sweep 2. You’re going to go to the surface and
you go to sweep2 rail. Rail1, rail2. You’re gonna go from here to here. Now
very important things as you need to go to this point by clicking the point on
the top. I’m going to show you what happened if you don’t do it. It will just
give you half of it, right? and then you probably need to do one more time here,
here, and go from here to the point, and it looked like this not much different,
because you can just join this one back but. In fact you got this is a two
surface joined together, now you have a polysurface. what is the disadvantage is
you can not turn on the control point on the polysurface, so I want to turn it on it
will say “cannot turn on the point for polysurface”. okay so I’m going to go
back one step. that’s do it one more time Sweep2, rail1,
rail2, going here to here and then make sure do you click to the point. okay
and now you look at this no seam right in the middle, and what it does is if we
need to do additional editing, and then we can turn on a control points. that way
we can turn it on so this is really important step. A lot of people, just you
know, don’t think this is not much different but it does make a
huge difference. okay so we want to cap it. so now we have that first one. okay
the the one on the side, I do like to do something more like this. Drawing a curve
roughly here, and I want to coming up a little bit and do a little bit more
curve, or something like this, alright. and then you can simply pipe it or you
can use any of the profile that you wanted to do. I’m going to creating the
profile and again use the (rectangular) conic corner and with the center (option), so let’s take a look
snapping into the end point of this curve and then we want to go to the
front view and to holding the SHIFT kind of eyeball like the size that you
like, and then click on it so you will have this curve right there and let’s go
ahead and sweep it, and see what does it look like. I’m going to use this sweep1 rail. I’m gonna click on this profile and then you have something like this.
Okay, the one that we have and look like it is kind of inside of the shape and I
do like it to come up a little bit more. So I may wanted to have this one going a
little bit and maybe you want to increasing the thickness on this one
so that way you will come up a little bit more, and I do not like this showing like little piece showing on the right side of the sweep we just had,
so I may want to just make it a little bit skinnier. Okay and you can do any of
the editing at this point, before you do anything make sure you cap this one so
that way they look nicer it’s ready to Boolean, okay you can do
any editing on this one, for example giving more of the dimension what you
can do is to click on this one and I want to use the bend tool, and kind of
bending this one just come out a little bit like this, so it giving a little bit
more dimension on it. okay and so we have that one. Let me get a slightly thicker
and also you can take a render view to see how they look. Alright so you have
something like this you can keep tweaking until you know the one you like.
I’m just gonna save our time here to finish this design going to mirror. Make
sure you snapping into the midpoint now we have a lot of things to snap here and
then so I have that over there okay and then I’m going to pick up all the
surface, and let’s go ahead copy from the midpoint of the curve and then we
want to copy to all of my point right here, midpoint there, and midpoint there.
okay so now we have all the copies. One more things I would like to do is I’m
gonna pick up all my prong and then and make sure that they are tilted outside a
little bit, so that way, you know, it will spread it out instead of a go straight.
Going straight will cutting into my stone too much. before I actually flow it back
I will also like to make fillet edges all the things on the top so I’m going
to try 0.2 millimeter, okay so they come out really good. Alright so now
it’s the time to get a flow back to the top
we need to creating a surface snapping into this end point to the end point, and
that gives us a good reference for where they are okay and let’s go to the
perspective (view) before we flow it back we want to make
sure we click on Rhino history and then we want to go to the transform, and you
have the “flow along the surface”. You want to pick up everything there, and I’m
going to try one of the corner. Let’s say this corner, and I’m gonna come back here
and click on this corner alright. so one more things here I
usually don’t like the one on the seam because it may not be correct but this
one look alright. okay so we no longer need this surface, and I want to
call out my curve right there and then we just need to pipe it or you can make
another profile to fit the profile most of the profile you had. We just need to
have some sort of support underneath it. Next thing we need to do is the bail, the
bail is quite simple. I’m gonna creating an arc like this, and then close
to where the middle I just gonna put tab right there, okay so this tab is
going to help us to have better curve. It will flow better, and I’m going to use
the blend tool to blend from this point at that point. okay so we have really
smooth blend over there. And let me trim or split by the point where the
quadrant is, right. so let’s delete the one on the bottom. Okay so now if I am
going to move this out a little bit, so easier for you to see. what we’d like to
do is—- we want to creating the profile so in this case I have this profile that’s
going to be somewhere like this. A little bit thinner than the prong,
and then we are going to have another profile looking at the top view again,
starting from the center, and this one I’d like to be a little bit thicker.
I don’t want to overpowering my pendant so we’ll have something like this. okay
and let’s go ahead to do the radius (fillet) first, so let’s filler all the corners.
this one I wanted to have 0.5 millimeter. That’s too big. let’s say we wanted to do
0.3 millimeter and this one already is gonna be really small let’s try
0.1 and see how it works. Looks alright, okay so we’re gonna use
the sweep1 rail, going from here to here and then so we’ll take a look and
then…. oh…. that’s a very good example here the reason it has almost like a twisting
surface there is because i didn’t move the arrow. so sometimes you just
cannot get lazy. Thinking that will pass Rhino it’s really honest! okay so
let’s move all of them back to the midpoint at the same time, alright so now
you see is much nicer. Alright so we have that one all we need to do is to mirror
to the other side so let’s go ahead to mirror this one back to here. Alright
now if you go ahead want to boolean this because it has an intersection you might
encounter some problems, so my trick is going to be using the cap tool, CAP command,
and you’re gonna cap this one and cap this one individually so they both
become solid then you want to boolean unit them. okay so that way you won’t
creating the problem for the boolean, and then we want to move it in a little bit.
Make sure you have a good contact, that way you will have a good casting.
okay and also little things here this one I usually like to do and that’s
for jewelry design specific purpose. I always like to move this one at lease align with
the bottom of my setting. The reason is that way it will be hanged correctly. It
will lay flat to your customers chest. okay so those are the little trick about
the jewelry design. I hope you enjoy the video and please like, and comment, and
share my video. That’s really important for me because that’s the ONLY way I can
continue making free videos for you. Thank you for watching. I’ll see you next
Monday.
