Hello everybody. Welcome back to PJ Chen Design today. What we're gonna do
is finish up this ring band from last video. Are you ready let's get started!
Last video, we were finishing up this rope type of design on two sides, and
today we're gonna talk about the braided design in the middle. If you want to find
out the video. It is on the right top corner, you were able to find a video
link over there. so back to what we have here, we kind of need to understand the
structure first. If we look at this pattern right here. It looks like it is
falling into some sort of a square, and it has kind of a v-shape coming up. One
is lower, one is higher. Once you create one, then you repeat multiple of them.
Alright so we're gonna come over here on our flat, so we can make any thickness
that we want. I'm going to snap into the midpoint, and just draw a rectangle. You
want to draw a little bit longer than what you have, so we have enough to
trim. We gonna rotate it 45 degrees. Let me move this back to the center, so
that's the first one. The second one, we are simply just going to mirror to the
other side, so we have this pattern here. Notice one has to go up one has to go
down, so those will be the line that we are going to sweep. Let's explode, and
we don't need those small line there. Shorter lines here, so I'm just gonna
delete this. Okay, so we are going to create our first cross section, you can
design the cross section that you like so you can use it simply for the oval.
I'm just gonna design something a little bit more organic form, so I'm gonna go
from here and then kind of going up and maybe coming down a little bit on my
right view, and coming down a little bit like this, and then close it up with the
straight line. so this is gonna be my profile. I'm going to move this
profile with the transform tool. Orient 2 Points and snap in endpoint
to endpoint here. Right here, I do want to copy, and I do want to scale as well, and
let's snap into this place, and also another one somewhere in the middle.
because we want to have more control on it, and the one at the end, we're gonna do
the same thing one over here, one somewhere in the middle, and one close to
the end, and we're gonna adjust that, so don't worry if it is not at the right place.
okay so now we have something like this. For this one,
we are going to start it front here. Somewhere when we get into the middle, I
would like to be a little bit taller, so I'm gonna use the 1D scale and let's
scale 1D roughly like this, and we were able to change it later on. When
it come in back to the end, I do want it to be a little bit shorter. so we want to
go something like this. Okay the same thing happened on this
side, I will like this one go a little bit taller right in the middle, and we're
gonna change that later. So don't worry if there's a hundred percent fit. Okay so
let's give it a try. We're going to use the command
Sweep 2 Rail. This is rail 1, and this is rail 2 and make sure that you record the history.
We're gonna go from here to here to here, and then we will get something like this
okay so it's a little bit bump over there, and then we're gonna do the same
thing over here. Rail 1, rail 2, cross section, is one, two, and three. And then we
make sure we want to record history as well. and we hit ENTER, and then we
got something like this. Okay so this is the part we need to do adjustment is
because now is completely crossed, and you have that cross looking. So I would like
to move this one and using the move tool so I can follow
the edge by moving in a little bit more. So you don't see that much, and you can
also adjust the high if the high is not what you want, and you can always like
moving back and forth, and adjust the high to be more suitable for your design.
Okay so for demonstration purpose, I'm going to stop here, but you do have the
option to edit this curve which is a cross-section, and also your rail.
Before we cap it we need to do a test on the pattern, so let's having this one, and
making a copy just next to it, and see how it looks. Now, looking like this is
hanging over there. This piece is hanging over there ,and we do want it to get into
the next body, so we actually need to have it more in the body here. Once we
moved in, you want to make sure that it's not sticking out and that will be your
pattern, so now we can delete this one, and delete this one. This is a good time
now let's go ahead to cap it, because we no longer need it to change it ,and then
if it says you break the history, that's okay. Alright so now let's take a
look the result, we gonna come over maximize the top view, and we're gonna do
linear array. How many do you need? I don't know. I'm just gonna try more
than what I need and I'm going to snap it, make sure my "near" is on, so I
can kind of slicing there. so they will align nicely, and then you can eyeball if
you want to have a gap, or you want them to overlapping a little bit. Okay so this
is the pattern that we have, and I'm going to delete some of them here.
So let's take a look if that looks nice to you. We are also going to... I think
I might make it too high, so I'm going to move it down a little bit by selecting
everybody, and looking at my side view, and they kind of move it
down, so the rope design well show. Now this is the pattern. Let's take a
look on the render view of that. So if you like the pattern, and you like you
know the bump and everything and we are able to trim it, but notice that, this
visually doesn't seems right in the center, so you might want to move it
up a little bit in right here, so visually it will look more in the center.
so now what we need to do is we need to trim the top and the bottom. Okay so
after Boolean Union, they become one piece and then we want to Boolean Difference
by drawing a block on the top and mirror that block to the other side, and
now let's go ahead to Boolean Difference. okay so now we have this. Again we need
to play with the texture right here, This is an empty space, if you flow just back
like that, you're gonna get that empty space, so what I like to do is I want to
pick a point as my reference point, so let's go ahead to use the move tool, and
I'm going to pick it up this point, this end point right here, and move that end
point to my edge so make sure my intersect is on. Now we know that
this is the point we're cutting, we want to come over here.
Draw a line close to the same point that we had there, and using that line to trim
the rest of it. So it's really rare they will be exactly the same
the first time you trim, and we're gonna use this one to trim the
extra. Okay so all we need to do is make sure they will be aligned perfectly.
Let's go ahead to use the 1D scale, and we want to scale from this point all
the way to the end, and moving up to the edge they will meet perfectly, when we
flow it back. So we need to come over here to creating the surface, and we are
gonna come over here using the transform- flow along surface,
we gonna pick up all of them. You can Boolean them if you want to. Let's pick
up one of the corner, and come over here, we want to pick it up the same corner
over here, so once you have it flow back. You're going to see this match really
nicely, if you cut it correctly. Okay one more trick that I would like to show you
this is still has the seam over there. To close the seam, the best way to do is
explode everything, and join back everything. So that way you will get the
solid polysurface here. Now, the last step, you go ahead to Boolean Union
all of them. I hope you enjoy the video, please like and comment and share
my video, so I can reach more people. Thank you for watching and I will see
you next!
