Hello everyone, Welcome back to PJ's CAD class. today we would like to build
this Superman ring. it is really popular to have all kind of logo, icon onto the
signet ring so we'll try to build one. I'm going to get the logo from Google
and just wanna claiming here it is for education purpose it's not meant for the
production. so what do we need for this ring the command you are going to use is
quite simple let's take a look at that first of all we'll go to picture frame
we'll use the picture frame to bring into the image which is a logo image of
the Superman from Google. Once we do that we will trace the image to get all the
curve then we can delete that image we search from the Google. Then we will use
the command call "Sweep 2 Rail" to creating the ring surface after that we will need to
cap the top to make a solid. So then you have a ring that's done then after that
you just need to select the Superman logo and using the commands called
"Extruded Planner Curve" to turn into the solid and then you will just use
Boolean difference to cut out the shape on the top. then it is done. so let's get started
when we searching for the image I try to find black and white, that would be easier
to track so something like this one will be great for tracing the image you
probably want to find a line quality is a little bit thinner. well at this
point they seems look it looks similar so I'm just gonna pick a line work and
then I'm trying to save the image and save to somewhere that you can find
alright, so then we'll come back to the Rhino when we come back to the Rhino
we just type it on the command type it "picture frame" and then it will ask you
to pick the image and then we'll just pick the one I just save and then
you're going to drag it a window I usually hold a SHIFT so there will be
like 90 degree at this point it doesn't matter how big they are because we just
need to get a line work after we do that and we can kind of scale to any size we
want. okay, so just want to make sure the line
I'm going to use it's not black I'm gonna turn it into the red color so
it will be easier to see before I do that I also like to lock the picture so
you won't like keep clicking on it okay so I'm just gonna use a straight line
and trying to get as close as possible
alright so since this is symmetrical so I'm going to do is to mirror this
curve and make sure you "OSnap" is on so we want to snapping into an end point
and then we just need to create a line in between those alright so once I have
done everything I'm going to join everything with this diamond shape and
then next one instead of tracing over I'm going to use the offset command
right now it's 1.3 mm so let me try 2 mm
still too small maybe 2.5. it's it's almost there 2.7
okay and again in your case it doesn't might be still too small maybe
three all right and in your case it it might be bigger
or smaller because we are not working in the exact size we just want to trace it
so next one I'm gonna use the straight line and do something like that okay so
to do the rest of a curve I like to use arc tool, the second one is start
endpoint start endpoint and the point on the arc so what I do for example on this
one I'll make sure my "near" is on, so it definite snapping into the curve holding
my shift and that will be intersect with the other one and I'm just moving down
like that so that way I can make sure that that one is symmetrical all right
so I'm gonna do the same thing right here snapping into the curve and have
something like that okay so the one more here
snapping here and here and something like that right if they are not perfect
you can always go back and turn on the control point which is F10 or you can
turn on control point here and it's kind of try to move it to make it you know
fit it better again turn on a control point and try to add it like this way
alright so the rest of it we will need to use the
control point curve and then we're just gonna trace as close as we can and
remember you can always come back and using the control point to edit, so if
that is that is not like super accurate don't worry
right now
okay so once we are done let's turn on the control point on this one alright
so I try to avoid any of like kink looking things so we just need to move
those control points until we get a very good result and to make it as close as
possible and I also need to do this part which is the straight line here and then
again with the arc from here to here like that okay I think we are pretty
good, alright. so let's go ahead and delete the background so it's easier to
see like this we want to select everything and then we want to trim the
part that we don't need it okay so that will be this part this part here here
here and then here, alright, I'll be careful I might have extra there. alright
so that's everything then once we are done
while it is selected we want to join everything and we want to group it as well so when
we move is easier right so now let's go to the front view I'm going to create
ring shank size like rest of my demonstration is 16 millimeter okay so
now this logo is way too big we want to size down into the size we feel is
comfortable you don't want it like way too big right so that's inside for ring
sharing I think that's at this size you can make it bigger smaller it's really
up to you okay so now we have we need to actually make sure it's in
the right position so the way we are going to do it I'm going to use my move
tool and wanna snapping into this end and to the quadrant there
alright if you look at the perspective they are there this logo is like right
in the middle of there right so we want to look at the top view again this time
we want to use the align tool and we want to align to the center alright
vertical center and you know I would just really need to type at zero and it
will be there right so what's the point is I need to have this point aligned
with the middle of my ring shank so that will look better it's really up to you
where you want a position I just feel like this look nicer in this way okay so
now we have the top is done we know where it is to the ring next what we
need to do is to create the shank so let's look at the front view I'm gonna
use the arc tool type in zero and then roughly about two millimeter
I create this like half round shape there right the next coming gonna use is
under the curve tool you have the extended curve from arc to the center of
to the point so I wanted to do is to create this arc
and snapping into the end point okay so let me do again pick the arc and
snapping into the end point all right so if we take a look at the perspective you're
going to see the shape of outline coming up okay so with this I want to
also creating some sort of a profile in the middle my goal is to do sweep 2 rail
and what that mean is this one this curve that's going to be split with the
point at the bottom okay so you got 2 curve
right now and this curve is going to sweep 2 follow this rail and this rail
go all the way to the bottom okay but if we do that we're gonna have this point
all the way to about it let me show you what it looks like if you have this one
and rail 1, rail 2, cross-section and it's gonna look something like this
right really pointed this is not what we want right so I kind of need to giving a
control right here right at the middle there so I'm gonna use the ellipse tool
kind of snapping into the cause one here cause in there
and then I want to see like how wide do I need it I roughly want about this
alright, so I'm just kind of eyeball like how wide I needed okay so we're gonna use
the exactly the same thing sleep 2, rail1, rail 2, you're gonna go from you
to you and make sure you select the point on the command bar here and
snapping into the quadrant all the endpoint right, the key for a good sweep
surface is you need to make sure you align the arrows nicely otherwise they
will go crazy okay so now we have this really nice smooth
surface you know am I just gonna click okay let's take a look on the ghost view
alright so really nice surface right here on the top is still empty we need
to make into the solid so I'm gonna use a command called cap "CAP" and then now
it is solid okay the next things to do is. this is our
ring size I'm going to extrude a planners curve straight and make sure it
is solid, right, so now we are having those two shape going to use the
"Boolean Difference" cut it out inside of ring shank. Alright so now we have this
rest of it we just need to cut out the pattern on the top so I'm gonna pick
up all the close curve here here and here all of them and use the same come
in under the solid you have extruded planar curve straight okay I don't want
to go way too deep probably just 1 millimeter so you type
it 1, enter you will go 1mm up and 1mm down okay the way the
reason I do both sides is because I want to make sure they are intersect. so
we use a boolean difference you kind of pick up this one and then use those are
the cutting tool to cut it off right for the boolean difference the trick I will
remember always pick up the one you want to keep and the second one will be the
one you want using as a cutting tool right so now we have this if you just
send this for render it doesn't look to it because you see all the sharp edges
so every time I do model I try to do the fillet the edge if possible or you want to do
bevel edges okay so on the radius for the ring shank I try let's try 0.3 mm
and see how how how does that look I look alright alright so we
gonna do 0.3 on the other side as well 0.3
okay alright and then on the top I don't want it to look around look like a
little bit bevel edges so I'm going to use the chamfer and let's try
0.5 and see how big it is you definitely don't want it to be too big
and cut into the pattern alright this look good let's take a look on the
render view okay that's look good alright this is what I have you for you
today is a super main signal ring please like and comment on my video and share
my video that helped me on the ranking at YouTube and also able to make it more
free video for you alright I will see you next time thank you for watching
