Hello everyone welcome back to PJ Chen Design channel. This channel is about
sharing Rhino3D knowledge to students and professionals learning various
Rhino 3D techniques. Today I would like to talk about this heart-shaped ring. Heart
has been symbol using in jewelry design in many different ways. Are you ready. Let's
get started.
We are going to start with the front view. Let's build a diameter for
16, like most of my demonstration, and then we are going to find a heart on
internet. You'll be surprised, it's much easier to trace the internet (image) instead of
try to build your own. That's because we have some visual things to follow up, so
you can just look at the shape, and pick the one that you like the most.
I happen to like this clean one and we're gonna alter it anyway, but I would
like you to pick up one from Google and save into your hard drive, or anywhere
you can find. So once you have it, let's go back to the Rhino. Let's move on
to the top view and in Rhino6, you can just type it "picture". In Rhino5, you
might need to type "picture frame" instead. So we have this heart, and I'm
going to put it somewhere over here. It doesn't matter the size at this point, we
just need to now easier to trace it, and we're gonna move it back. so I'm just
gonna put approximately the size and I'm gonna trace the outline. so to trace it
I'm just gonna use the red color, it's easier to see, because I am in the black
background, so let's move to the red color, and when you try to trace. It's
okay if they are not 100 percent follow the shape, because we can always
turn on the control point and try to edit it.
Okay so now I have this one here, and I'm gonna turn on a control point, and try to
move it as close to the design as possible. So we try to move all those
points in and out a little bit, so that way they will follow the shape. You can
also free-hand to draw this heart, if you want to. But I find out it's much easier
to do this way. Now we no longer need this one. The key things for this heart
is you need to have the first point and the very last point lining up. They are
two ways to do it. I'm going to show you both ways. The first way is I'm going to
pick up the end point on this point, and make sure on this point and make sure my
Smart Track is on. So I'm going to use the Move tool, and make sure that it's
aligned with the first end point, so that way they will be aligned for sure.
the the reason we do that is because we want to mirror it. Okay so now
they are aligned. I can move it back there. The second way to do it is
using the set point, so you type it "Setpt" on your command bar, and you want
to pick up the point you want to set. which is those two point it. Hit ENTER.
and we want to align to x axis at this situation. Then we click OK. now you can
move them to anywhere for those two points and they will be align. I'm
going to just snap it back to the first point there, so now if I do Mirror, they
will be exactly right in the middle okay so this is my first heart, you can take a
look on it, if you want to keep editing, you can do it at this point.
so that's join it, and move it to the top of our ring, using the Gumball, holding the
SHIFT key, and scale it down. Alright I also want to make sure this
ring is align... the points are aligned with y-axis, so I'm going to use the align
tool, and align to the center, and I actually like to type in 0, so that way
this one will be aligned to the center. I'm just gonna move it down a little bit
so that is where the ring shank is going to touch both side of the heart. okay,
The heart you can be creative. The way I'm going to do is going to scale down a
little bit. Use the gumball, holding the SHIFT key and hit ALT key
right here, you see the "+" sign, and you can release your mouse. Okay now if I
have the heart like this way, it's okay on the design, but I do like it more be
more interesting, so I'm just gonna edit those control point, kind of bringing a
little bit like this side, and kind of bring this one up a little bit too. You
can be really creative to to see you know how you like the heart as
offset, so that way you won't end up with the same thickness. So I'm just gonna
tweak a little bit here and there, and to find the best proportion for my design.
I'm going to fast forward a little bit here so you won't feel bored watching me
doing this.
now we have this. This is well be the two rails for us to sweep, we need to create
in the profile so I'm gonna coming over here, and let's go ahead to use the
square, and you want the round corner, and I do like a conic corner so
let's go ahead to use the "three-point" I'm gonna snap in here, and here for our
first two points, and let's go to the right view to see how high you want it to be.
Alright so I get the first shape there. The second shape, I'm going to click on
my perspective view again with those three point, and then want to
make sure that they are not exact the same height to be more interesting on
the design, and I wanted to have them like something like this, okay, so we got
two conic square, conic corner square. Okay let's try a sweep and see how they
look. Going to the surface, we have "sweep 2 rail" so this is your rail1,
rail2, cross-section. okay and make sure they are aligned perfectly, which in
this way aligned to the bottom, and the arrows all face interior. Okay, so you got
this really crazy shape, but I don't want it to be so dramatic, so make sure you
click "maintain height", so they will be the same height, just change the
thickness. Okay we also want to "close the sweep" so they will do on the other side
okay now we click OK, then we will get this shape. okay so let's go ahead to
move this shape on top of our ring. Alright at this point, if you feel like
this is like too big, you don't like it, you want to scale it down, you could
do it at this point, alright so I'm gonna hide this curve, so it's not
gonna bother us. Alright so we have this heart
now with this heart, it doesn't follow the ring shank over there, so I do want
it to follow the ring shank. The most easy way that I found is the simple
command call "band", and I'm going to snap to the middle, and kind of bend it to
follow to the ring shank as close as possible. okay I'm gonna do one more time
to do on the other side. Alright now I have this, I can move it really close to
the bottom. Okay I'm gonna have it.... actually you're going to see it
like a little bit lower than the black line, so I can trim it later to be a
clean cut on the bottom, so I just kind of have it just a little bit lower. Okay
Now we have done the top, you can see we have very nice heart over there. What
we're going to do is to do the ring shank. The design that I have is you have
a ring shank kind of coming down, and go into the halfway, so
I'm gonna use the technique that I use a lot in many other model... is I am going to put
two little tags here. It's going to be right here, Alright I'm
going to move it a little bit. Alright so now you see I have two little straight
lines right there. Instead of drawing a line, I'm going to use the "blend" tool, we
are going to blend from here to here. okay so you get a really smooth blend
there, and I might need to move it just a little bit to make it more to the shape
that I want. Okay make sure you don't want to join it, because we are going to
delete those two straight lines that we just draw earlier. Okay so now we have
this, we just kind of simply using the "pipe" tool and I'm going to pipe
something really big there and something a little bit small over here.
okay and then maybe you want to move it a little bit. Move it down a little bit
it's really up to you how you like to do it, but I would like to take a look on
the perspective (view) and see how they look, and sometimes if it is hard to see you
can turn on the render view, and see how they actually look over there. okay so
you can tweak it into the way you like it. To save (tutorial) time I'm not gonna change
much at this point. Okay so now we need to create the rest of the ring shank. I'm
going to extract the surface only on this one, and delete that one, and to
mirror this guy to the other side. I'm going to use the "mirror", type "0", and
then I can mirror to the other side. The rest of it we can use the "Sweep1 Rail" and
we're gonna sweep from this surface edge to this surface edge, and make sure they are
aligned. okay so let's click OK. Now don't forget to
join them, so they will be solid. This will be our ring. I'm going to go ahead
to "boolean unit" those two first, and then we are going to go to the solid, and you
have "extrude planar curve- straight" and let's go ahead to "boolean union" those
two. Alright so then we will have this very nice ring. Inside of ring shank
is really clean, so now we finish this ring the rest of it is putting a stone in
there. I already pre- build this prong-set over there. The similar idea to make
this setting, you can go to my Youtube channel. One of the video that I have
,actually the very first video, is how to build a bezel-set pendant. It has a lot
of detail talking about the stones' (part) name and what is the proper
to build a prong and the bezel. So you can check on this video. It has a lot of
good information for you. To tell you how to actually build a setting for this
stone, so I'm not going to spend time to tell you the same thing just go ahead
and checking on that video, so once you have this, all you need to do is boolean
this setting into the ring. Make sure that your setting the bottom of the
culet is not stick it out. if your stone is bigger than what I have.
I hope you liked this video please like and comment and share this video that is
a great help for my channel and that's the only way I can keep making free
tutorial for you. Thank you for watching and I'll see you next Monday
