Men’s Tire Ring 3D Modeling in Rhino 6 (2018)- Jewelry CAD Design Tutorial #37

Hello everyone welcome back to PJ Chen
Design channel. This channel is about sharing Rhino3d knowledge to students
and professionals learning various Rhino 3D technique. Today what we’d like to
do is to make this tire ring. It’s inspired by car tire and it has been a
big inspiration for a lot of men’s jewelry. Are you ready let’s get started. before we start this ring let’s talk
about some detail of the pattern. I would like to use the pattern as
simple as possible, and try to avoid too much the sharp angles. Something like this
I try to fillet a little bit to avoid the sharp angle, but you don’t want to
pick up the pattern that’s too pointed and for men’s jewelry it’s not necessary
to put a lot of stone in there. I just put it there for the decoration. So we
won’t talk about a stone part, but about the entire model. Let’s take a look
on the Google search image. Few things you may want to avoid. First of all, the
tire pattern has coming to the point because that may cause the casting issue.
This one is not too bad but the pattern is too complicated so what we’d like to
do is picking up some pattern is simpler, and doesn’t have too much pointed angles.
So we are not looking at the actual tire. We want to look at those black
and white image. You can click on any of them and take a look in the detail, or
usually going view more so they are some a very good one, like this one
is way too complicated. Try not to use it. this one you may able to simplify. Okay
so try not to take something like this These already have some style on it, then
let’s go back to Rhino. We want to start at front
view let’s draw a circle. Center is at zero. For diameter that’s type it 16 here. Alright and then let’s go to the right view and
this time we want to make a profile. The profile is the tire basically outline. So
what I like to do is to create a square roughly you don’t want to get it to wide.
I think men jewelry, if you over 8 mm It might be too much, so somewhere
around 8 mm will be great. The thickness right here, we want to set it
up for roughly about 3 (mm). This is still comfortable. If you get it more like a
5 millimeter, it may not be comfortable for men’s jewelry. So I’m
going to move this one to the center back to where our ring circle is.
Let’s modify this area a little bit because I like it to be a comfort fit,
so what I’d like to do is using the arc to kind of make the inside a little bit
rounded. It’s gonna use this one to trim the rectangular that we just created. okay
and then on the top I would like to use the arc again to create something a
little bit bigger in the depth and then use that to trim off the rectangular
again. so we’re gonna trim off this one alright. Although inside is already
comfort fit. It’s not so comfortable on those angles, so I’m gonna use the fillet
curve to set it up for 0.8 (mm) in my case. Let’s run off inside a little bit. Alright, so
on the top I might also want to round it off as well and you can change the
fillet radius to make whatever profile you want.
Once you’re done everything, let’s join it. And making this ring is very
simple. We’re gonna use the command called “sweep 1 rail”, And let’s go ahead to pick up the rail and the cross section, and let’s click okay.
Alright so you may wonder what is that black line over there.
This black line is where the seam is, and this is really important that we move
the seam to inside of the ring shank. because that will affect the “create UV
curve” if you have a seam, it’s not right in the middle. Okay so let’s go ahead to
use the command. It’s leaving under the surface tool and you have this one is
“adjust closed surface seam”. It will ask you to pick up the object. So let’s pick
up this object. We don’t need to change both of them. So we want to do… let’s
guess… using the U, and then we want to make sure snapping into the quadrant.
so now the seam is right in the middle so the next step is, we need to know
where is the area we want to draw this tire (pattern) so let me go ahead to make a line
right there, and make sure the line is really close to where the tangent area
on the top view. Let me go ahead to copy and paste and hide one of these. So we can
bring back later. Alright. so let’s pick up these two lines, and go
ahead and to use the trim, and trim off the extra over there. Alright, so the
reason I’m doing this is because I need to know where is the area for my tire. So
this will be the area that we are going to work with the command. We are going to
use is living under the “curve- curve from the object”.
You have “create UV curve”, so now what are you seeing here is the area of that
surface, and what is coming over here in this button and the top that is original
the whole ring area, and we only want to design in this rectangular area, but we
have to keep all of them for the reference okay.
so let’s bring in the tire pattern by “picture” command, or “picture frame”
in Rhino 5. We want to bring in the command right here, and the size doesn’t
matter at this point. We do want to have a clear image to trace with. So with this image, let’s go ahead to trace with the line. I like to use the red colors so
let me create another layer, and then make this layer in the red color so it’s
easier for us to see. Alright so I’m gonna use the straight line work to
create this. Sometimes you can hold SHIFT key, and you are able to make a
straight line and because this line is going to back to align with this. So make
sure your “smart track” is on and then you snapping into this point first, and
then you can move it back to snapping in here. okay so that’s the first one, and I
also want to trace right here, and holding the SHIFT coming back here,
holding the SHIFT again then coming back here. alright so now I have this. I’m
going to create another curve going from here to here.
and because I want them to be parallel so I’m just gonna use the gumball drag it
and hit OK. so I will get those two are parallel. The way I’m going to create is
just using the “blend” tool. I’m going to blend the curve from this point to this
point, and then you can adjust it to make it higher or lower, or whatever you
want on your design. okay so let me go ahead to join those to make it look more
uniform. I was simply just making another copy by
using the “rotate” tool and using the gumball to move it to this side. Okay so
let’s use the “Move” tool to be very accurate and snapping into the line
there. Alright so I got that one, and I also just want to use the “mirror” tool to
mirror the other one back here, and kind of tilted a little bit to fit the
design right there. so at least they don’t look like they all different, and
this they look really similar. Okay so now we have all of them. Just go ahead to
select all curves, and let’s use a trim tool to trim the extra and we’re gonna have that one to trim
off this one, so now let’s joining all so now that’s join all of
them together alright so we no longer need this background we
can delete it but before I delete this background, I would like to mirror all the curves that we have to the other side. Just full of reference,
we’re gonna change the distant based on what we have, but just want to get an
idea for the proportion, so let’s mirror to the other side now let me delete
the background so it’s easier for you to see. Alright so now we got those two
curve I’m gonna move it close to our design and turn a 90-degree over there.
and move it somewhere here. Alright so now you can scale bigger or smaller,
it really depends on how you like them close to the edge.
okay so I’m going to align them but before I do that, I want to group those
two and I want to pick up my rectangular shape and let’s do the “horizontal center”
align and snapping into the midpoint so that way they will align close to the edge that I like. Alright so this
looked nice and then we are going to do one more
things to do a test. Let’s go ahead to using the array tool. It’s “linear array”
and we’re gonna array this guy. How many of them? I’m not so sure so let’s try 25
first, and the first reference point is any of the end point and you can kind of
eyeball the distance that you like after you try a few times, you find a
perfect gap a lot of time they don’t end up exactly
where to match the first one. I like to do is instead of trying to
trim and doing it everything, I would like to do just 1D scale this
rectangular (shape), so let’s go ahead with the scale 1D , and let’s go ahead to
make this snapping into the end point. alright so we kind of stretch it a
little bit to back to our design, That’s alright. Because this is the
pattern so it doesn’t affect too much. next step let’s go ahead to make it into
solid, so that’s going to the solid tool. extremely plain a curve straight and I
want them to be on the both sides because I can actually have an
intersection to the ring that we have and I don’t want it to be like too thick
because my ring is already three millimeter so let’s go ahead to set it
about 0.8 millimeter on each side okay so now we have this. All we need to do is
flow it back there. Before we flow it back we may want to do some fillet on the
edges to make sure they are not too sharp first .So let’s go ahead to do this.
We’re gonna go into the front view or right view. On the top, let’s use the fillet
and giving a little bit radius. Let’s say 0.2 on all of them. okay so now we have
the fillet and double check to click on two of them and make sure that they are
closed poly surfaces. Okay before you flow it back to the surface ,one thing we
wanted to do is we want the edge to be smooth so this is kind of stick it out
and it won’t be comfortable for the ring. so you select everybody here,
not the curve there, and we’re gonna use the command call “Edge Edit”. Alright we
want to pick up on the bounding box and hit ENTER. The XYZ point at this point is
4, what we need is actually Y, so we don’t have to change anything here, and
then very quickly you are going to see something like this. Alright it’s easier
for us to see on the side view. I’m going to pick at the very end at the right
view, and then we scale it down like this try to get it as close as possible.
because that’s showing how much of the edge is going to hanging over there.
Alright so now our shape has become taper you can see from our perspective. okay
let me change this back to the black color. alright so you probably see it easier.
so you kind of see it’s become a little bit curved. They are tapered there.
alright so that will be comfortable for our rings. so that’s group them. You
don’t have to draw a window all the time, so that’s it group them and then let’s
flow this back so to flow this back to the ring, I will need to have a surface.
so let’s go ahead to make this surface by “surface from planar curve”. Alright so
the command we’re gonna use is under the “transform” you have “flow along the
surface”. We want to pick up this object and we want to pick up one of the corner
and let’s go ahead to pick up one of a corner in the target. Alright so it
looked very well but just be double check to make sure that the edges look
really nice. Alright so we don’t want this surface right there. because we make
a copy earlier and then go ahead to bring in the copy, so now we
have this ring here that’s double check that see the render view, and see how
they go. This is the tire ring for today’s demonstration. I hope you enjoy
it. please like and command and share my
video that will really help me to reach more people and share my knowledge. thank
you for watching. I hope you enjoy and see you next Monday

  5. Thank you Very much PJ for this tutorial.

    Why did you tapered 1 end of the tyre pattern before transferring it to the ring?
