Hello everyone, welcome back to PJ Chen
Design channel. Today’s video we are going to talk about this very popular
infinity pendant. Are you ready? Let’s get started! we are going to start in
building a curve you could do more spontaneous way by drawing a curve like
this way and then turn on this for the adjustment but I would like to have
something really symmetrical. So this is the way I will do. I will use the ellipse
tool. Turn on my Grid Snap, because I want everything symmetrical. and they
will be following the construction plane. So once I have that. I’m going to mirror
that to the other side. Okay, so we need to have an opening right here. Just going
to use a circle tool to draw something like roughly where that opening is going
to be, and I’m gonna use that to trim the middle off. Once we have done
that, we can use the blend tool to blend the curve from this point to that
point, and you will have this window right here. and we’re going to blend one
more time from here to here. Okay alright one of the problem you’re going to have is because it’s infinity, and if we join
all of them it’s going to be continue piece, so when we are
turning in this into the solid for example, if I just simply just pipe it
you’re going to see is the form is intersect into itself, and we cannot
boolean this, and you won’t able to print. So we need to do a little bit
adjustment by split this one, and with the point on this end, and on this end.
So they are becoming like two separate ones. For example, if I just go
ahead to pull those point up like this, it will look like a bump there. so we
need to make sure that the curve that we have is a continual one. So what we
wanted to do is rebuild both of them at the same time. Since it
is symmetrical. so we want to use the command “rebuild”. In the rebuild, you’re
going to have this dialogue coming up, we want to rebuild as less points as
possible, but still maintain the shape. So I’m gonna change to eight, and let’s take
a look. So now we have this one, I can simply just bring the one on the top.
Let’s moving up a little bit, and you can see this is a really smooth move.
So now what we wanted to do is to create a profile with the conic corners
rectangle, and we’re gonna snapping into this Center in the option,
and then we’re gonna go to the end point Let’s come over here at the front (view), and we
are going to set it roughly about two millimeters or depends on how big of the
stone you want to set it in there. So that’s one. Since this is
symmetrical, we’re just gonna mirror to the other side over there. So
let’s do a test there. You’re going to have this one, and let’s go ahead to use
the command for “sweep 1 rail” going from here to here, and make sure they
both aligned and in the same direction. So that will be the one, and this
one will again, we’re going to use this cross section, and this cross section, and
there will be something like this. so now we have this on the top we need
to make sure they both CAP. so both half become solid right there, and then we
were able to join them. And then we were able to Boolean them. so that’s hit
Boolean Union. Now we have the shape over here to do the stone setting.
We’ll need to find out the area we are going to put the stone in there. so I’m
going to use the command that’s called Extract Isocurve, and we are going to pick
up this surface right there, and somewhere in the middle is where we want
to have a stone to sit on. So this is where the stone is
going to sit on so that will be the curve. I’m going to turn into the red
color there, and then we are going to know like how long is this curve by pick
up the curve and use the command call Length, and this 33.138, so let’s create a curve 33.138 and then we hit
Enter, so we’ll get this curve here. This curve is represent if this one’s
stretched completely and then that’s how it’s become, and we are going to call in
the stone that we did before in other tutorial. and I will put the link there
on the on the side so you will know how to build a stone, and how to build a
prong. Now we have the stone sitting in there, I want to make sure is aligned
perfectly. So let’s use the align horizontal, so then we have something
there. okay on the top you want to move a little bit higher. This line right here
is representing the surface, so one depends how tall you want your stone sit
in. Now we have something like this, we’re simply just gonna use the
linear array, and depends on how many stone you want. I’m just guessing about
15 stones, and I want them to go like this. Get it as close as possible but you
don’t want them touching. Now let’s group all those 15 stone make them
aligned in the center so something like this. okay now this is the stones, we are
going to flow it back to this curve right there.
So we are going to use the command is under the transform, we have flow along
the curve. Pick up the object and this is where the base curve, and this is the
target curve, so then you will see the stone flowing on the top of the location.
And you can cut the seat for is for the stone sit better. I hope you enjoy the
video. Please like and share it and comment
so I can reach more people like you, who want to learn Rhino. Thank
you, and I will see you next!
