Hello everyone welcome back to PJ Chen Design Channel
I have the questions from the Youtube subscriber Issac asking about the
technique how to do this braided design here and rope looking design over here.
So today we are going to go over with this techniques. Are you ready? Let's get
started!
There are three parts in this ring. First is the ring itself. The second
one is the rope looking design over there. The third one is the braided
design over here. So we are going to talk about those three parts separately. Let's
starting with the ring. We're going to use these circles. Set it up the radius
for 8, diameter for 16, and then we're gonna come into the right view.
We want to draw a profile here. I always like the cushion looking thing so let's
used the conic corner, and then you can do any size of the ring that you like
it's gonna be really wide over here, and we're gonna moving in a little bit, so it
gives a little bit more like a comfort fit. Let's move the center back to
the center over here. The second we need to decide how deep it's going to cut
into. Let's draw a rectangle here with the center and this is going to show
like how deep we are going to cut into. And again there's no specific dimension,
it is just about your design. We are going to use the
trim tool to trim off anything in between make sure you give a little bit
fillet here, so the ring rendering will look very nice. On the bottom, you
don't have to worry about it. Okay so this is the curve that we have. Let's
joined it, and let's make a ring by using the Sweep 1 Rail, and this is the rail,
this is the cross section, then we get a ring like this. let's take a look on the
perspective. Now we have this on the perspective, and we only need to use the
one two flow is the surface right there in the center. So let me extract the
surface, and we're gonna extract the one over here. Let me turn it
into the red color, so we have something here to create a UV curve. The command
we're gonna use create UV curve, and then we pick up this red one, and this is
area we are going to design. So let's take a look on the top view. this is an
area we're going to design, and we need to separate them into three section, so I
kind of need to know how big they are first. So let's say, we have 5.94 mm
I'm going to have the area in
the center for 3.5 mm x 3.5 mm
and this is the area for the braided design. So I'm going to align
this with the horizontal Center, and the rest of this space is for the rope
looking design. so let's come over here. Let's do the Rope first. To make
our Rope look really nice, we need to know the dimension over here. This one is
1.22. so I like to create a rectangle here. This is 1.22 x 1.22
so we are going to work within here. Let's go
ahead to draw a diagonal line right here. So half of a rope should fit it into
right here. We are going to draw a reference here roughly about 0.4 mm,
And I want to snapping into this edge here, and doing the same
0.4 mm, and snapping right here. what I would do here is because we need
to have a two symmetrical side, so let's go ahead to use that as our first point.
and you kind of want to draw a curve of your own design, but you will need to
snapping in those two ends, and you can edit those to fit your design better.
but pretty much this is the first curve. We will have this one.
Using the rotate tool, snapping into this midpoint, and we want to rotate it 180
degrees. then there was snapping into right point the
should snapping into the right point. Let's double check. Oh, it's not there,
just need to make sure they move it back to the end point, so you won't have the
problem. When you try to create the surface. This one does meet.
then we will need to create the Cross Section. I'm going to have the oval or
ellipse tool, and I want to do something like this, and coming over to the right
view, and we don't need super high. We probably need it just less than 0.5 mm
So roughly like that. so half of this oval is less than 0.5 millimeter
for the thickness. Let's use command call Sweep 2 Rail.
This is rail 1, rail 2, make sure you want to starting with the point, and then
going to the cross-section, and end up with the point one more time.
You will get a solid. Let's double make sure this is a closed surface. Now we
have one element right here. Let's do a test, and see how it goes. Let's make a
duplication of this one. We are going to use the Linear Array, and I don't know
how many of them that I need. I'm just gonna guess 100, and we're gonna go
from here to anywhere, but make sure you stay with the line, so they will be
aligned perfectly. Okay, you can get it tighter, you can get a looser, it is up to
your design. Okay so I'm gonna get something similar like this, and take a
look if this is enough for you, and this more than enough. So I'm just gonna
delete some of them right there. We are going to flow this back to the surface.
If you have an empty space right here, then you probably won't flow
correctly, so what I like to do, first is I actually want to boolean all the forms.
Let's use the boolean union. Okay so once they are boolean, I'm going to move
with this is my guideline, and move it to the edge right there. So you're
gonna notice like everything will moving a little bit.
If this one is right at the edge right here then once you flow it back it will be
perfectly meet. So we're gonna do a little bit change here. We're gonna use
the trim command. Let's using this big frame, and trim off the one over here. So
now on the other side, we need to make sure it's perfectly aligned over there.
So what we're gonna do is we're going to use the straight line, and snapping it to
the end point right here. Draw a straight line down and using this line to trim
over here. Okay, so now with that little extra. This is my little trick over here.
Let's go ahead to use the Scale 1D. We're gonna snapping into this point
right here, and then the first reference point
let's snap into the end point right here. Okay holding your SHIFT and bring
it back to this edge, so when they flow it back there, it will be hundred-percent
contact. So now we have this side, we just need to mirror to the other side. So
using the middle as a center, and then we have that done. Next video, I'm going to
show you how to do the middle part, and then we will flow the whole thing back
to the ring. Don't forget to like and comment, and share my video, so I can
reach more people. Thank you for watching I'll see you next!
