Hello everyone, welcome back to PJ Chen Design. I would like to show you today a
two different ways to make this ginkgo leaf type of earrings. Are you ready?
Let's get started!
We will need to have a leaf shape to trace over. So go to the google. Type
Ginkgo leaf here, and that way can help you to find all different kind of the leaves,
and the shape that you like. So pick one you like, and download it to import into
the Rhino. So we're gonna use the command called "Picture", and we can bring
in any of the leaf that we found that we like, and you can position into any angle
that you like. You don't need to have it exactly the same, but we just gonna
use as a guideline. For example, this is definitely off right there, so I'm going
to trace anyway for something really close, and I'll change it later. so I'm
gonna start here, holding my SHIFT and kind of go over with the shape. Try to
get as close, but you don't have to get into every tiny corner. In fact, you want
to avoid really sharp corner. We want something really nice and round for the
jewelry casting purpose. You can get it really tight, if you want to, but
after polish, if this is a really small, it probably not gonna see anyway. So we
just want to get an impression of the Ginkgo leaf. I'm trying to trace
something and come over here kind of imagine what that look like. You wanted
to end to be a line, so make sure the Smart Track is on, so you can snapping
here and holding the SHIFT so that will be the same high possible. I didn't trace
it correctly so I'm just gonna move it down a little bit. Now this is
the shape that we have. We no longer need this one, so let's go ahead to hide
the background. Now you're looking at this one, and go ahead to
adjust any of the curve, that it's going to look better on your design. Again, we
are using it for reference, not saying that we have to get it exactly the same.
as long as it looks like a ginkgo leaf. I'm going to move it more close
to what I think the center is, and try to modify those curve and to make it look
nicer, and a little bit more symmetrical. Again you can
adjust those leaf, and see which you may not want it comes in that
much like, that may be too much there. Anyway doing your own design and
they are two ways I wanted to show you. The first way, we are going to
adjust the control point. So I need to make some adjustment on those curve.
First of all, I'm going to use the split command with the point, and let's split
somewhere about right here, and right here.
Then I have it into three different curves. Second, I'm going to draw a
straight line somewhere about here. Go all the way pass the lowest
part, and then you can make it as long as you want. and the third one
we do need to have this extended longer, so let's go ahead to use the curve-
extend the curve, and we want to extend straight. So let's pick the line. Let's
go to do something like that. Do it one more time, we want to do end. And go to do
something like that. So you may wonder, why am I doing this, because I
need to creating the surface that is bigger than this area, so I can trim it later.
Now we have line 1, line 2, line 3. So we are going to use the "loft"
command, and then we're going to go from here to here to here.
Now you look at that this area, it has some extra surface there. the
reason is the curve that we have right here on the first one. It was extended so
that actually they are two curves there. so the way of the Rhino calculation
will make extra surface there. To solve that problem, we just need to pick up
those two, and we are going to use the commands called "Rebuild", and we want to
rebuild to 20 of them. I think it's good it's because it's
doesn't changing way too much okay so we're gonna do 20 of them, and let's do
the "Loft" command one more time. One, two, three, so now we have something like this.
in order to get that wavy kind of
surface, we need to have a lot more control points, so I gonna rebuild a surface and
let's rebuild it to 19 by 20 so that's definitely enough make sure the
degree is equal 3 on both U and V, and we click OK. Now we have
if we want to turn on a control point, and again you can make it a lot more, if
you want to. Let's take a look on this perspective view. They are flat
and we need to make them like skirt or like a ripple effect, so I'm going to
pick up any of the point that I think I want them to go up. It doesn't have to go
in the certain order. You can have every others, or whatever that you think that
will work better, and I kind of render and pick up some point, and I want to
select the point all the way to the top. So the way is going to this "selection
tool". You have selecting point and you want to select the either U or V, and
in this case wanna select to the V. Now they are selected. Let's go ahead to
deselect anything's over there, and let's take a look on other view.
Now we are at the right view. I'm simply just kind of use the
rotate tool, and I'm going to rotate it a little bit up like this. Now we have
something wavy like that, and see if that is what you want. What we can do also is
I'm going to use that to trim those extra there, and if you cannot trim it's
probably because we did a rebuild, so this point is not touching the line
anymore. So what you need to do is moving this line with the "near" is on. On the
Osnap, and snapping into the edge. let's check on the other side. It's the same.
It's not on the right place. So let's go ahead and snapping into the "near" point.
I may want to have this one go inside as well. You have
something like that. Now what we need to do is pick up this curve and
then we trim this one over here. Now we have this. If it is not high
enough, you can kind of make a bump here, If you want to. So this is the first way
to make this wavy type of organic looking ginkgo leaf. Let's take a look on
the second way. The second way that we want to creating is very
different from the first one. We are going to use the sweep, so we need to
create the cross section in some areas. The first things I would like to
do is creating a cross section with the "arc" tool. I'm gonna snapping into the end
point here, end point here. and I'm gonna come over to the left view, and click on
that, so you can see there's a half round there. I'm going to create another half
round somewhere around here, and then again, I want to come over here. So make
the depth there. Let's saying that a surface from this point to this point
it should be round instead of flat. A lot like the first one. The second things we
wanted to do is creating more shape in between. I'm gonna come over here, and
create some sort of shape right here for whatever that's going to look good to
you, and I'm gonna do one more time roughly about here. something like this.
the third one we're gonna use the
outline. Basically, all we need to do is using the split tool, and split
somewhere here to here. So this is will be the third one.
One thing we will need to do is to make sure that all of this has the same
point. It's easier for us to edit it. We're gonna select all of them,
and we're gonna use the "rebuild" and let's rebuilt to 20 look good to me
for all of them. Even though this is gonna be a little bit rounded, but that's
fine. We're gonna click on OK, and this will be our new shape.The way we
are going to do is we're gonna pick up those point individually, like whatever
is spontaneous or whatever it's gonna fit into your design, and I'm going to
gradually to bring it up. So I'm going to bring this up for 0.5 mm
You can see it's kind of giving some wavy structure or wavy line
there. This one too. I'm going to pick up.... you don't have to pick up exactly the
same point from the first one, because it's going to be organic, so just do a
few tests and see which one works for you.
This one I'm going to bring up instead of 0.5, I may want to bring up for 0.7. Okay so a
little bit higher. The one over here again I going to
I'm going to pick up the points. so let's go here, here, here, here. Okay so that
that's gonna make it really organic because the point that I picking up is
not align with the previous one. This one I want to go up to 0.9
Okay so it's kind of gradually changing, I would just want to make sure
that this is not too much of a bump, because we were having point five at the
first one, so I want to make sure it's less than point five on the high.
Now we have something like this.Let's do a test. The command we're going to use
is called "Sweep 2 Rail". This is going to be the rail one, this will be a rail two.
You we're gonna go from here, here, here, here, and here. Now we have this
option you can maintain the high. So it's not like having to too much bump
there, and then this is what we're going to get, and again you can make it higher
lower, more organic or something like that.
Be really careful I might have the surface folding here, so I might need
to do it again. Maybe need to move those points, okay so I fixed that
by redoing moving the point and redo again, so this will be our surface.
To turn it into the solid we just need to mirror that to the other side, and you
will have the gap in between. For this gap what we wanted to do is we want to
use the curve that is fitting exactly the profile, and let's go to the surface
and let's do "extrude curve-straight" alright so we need to use this and that
those two curve to trim the area for this one, and for this one. So
that leave the something in the middle. And we can just go ahead and join it
and the same time don't forget the top. it is still empty over there, so we need
to cap this one. So double-check this is a
close solid polished surface here on the property. After that you can set some
bezel set stones. if you're interesting about a stone setting, I have a whole
course talking about 10-11 different type of a setting. I'll put the
link below and also on the right top corner, you're gonna get the link. So we
can make this into a earring, I hope you enjoyed. Thank you for watching. Leave
comments, let me know how you're doing or anything else that you would like to see
in the channel. Thank you and I will see you next.
