Heart Ring Modeling in Rhino 6 (2018)- Jewelry CAD Design Tutorial #35


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

  2. I ve just started to learn designing jewelry few weeks ago.. Your channel is the first one helping me about modeling in Rhino.. Thank a lot PJ. Hope to see more videos of you..

  3. Buongiorno, grazie per tutti i bei video che ci proponi… posso chiederti un aiuto? in occasione del battesimo cattolico (quando nasce un bambino qui in Italia, vengono battezzati) si regalano sovente oggetti con un piedino (little foot) di un bambino… ma come si disegna un piedino? potresti darmi qualche suggerimento per il disegno di un "little foot"? grazie

  4. I just start to learn rhino but not easy for me to starting,can PJ let me know which is the simple step i need to start
