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!
