welcome back to pj train design this is pj today i would like to use a rhino 7 supply tool
to quickly do three different sketch for the chair idea and hopefully that will help you
on your design process are you ready let's get started
there are three quick uh sketch chairs right here they basically are the same but it's really easy
for to do the variation in the sub-d so that's starting from the scratch so i'm gonna coming into
the right now you can doing on any of the view we are going to use those sub-d tool
and the sub-d tool that we're going to use first is the softly box on the top you can changing x
y z number and let me show you what that is if you draw any of the box like this in the sub d
my x y z is five by five by five so you can see five faces here on the x y and the z and that's
how you get this box i always like to have my object right in the middle so we're gonna use
the command for align centers on my top view and i'm going to snapping into the zero once
we're starting from zero and then we can start editing now in the subtly you do have the tab
key on your keyboard if you press it and you are turning into the box view right sometimes
it's easier for us to see it so let's go ahead to stay within the box view and we just need to have
a basic shape of the chair so we don't need the whole box coming over here on the top you have
a sub the filter then we want to choose the face so let's go ahead to choose those face right there
and maybe i want to keep it the the arm is a little bit higher and we want to delete those
so then let's give us a box there and we actually don't need this line right there so let me did it
even more i'm going to go into the wireframe and we're simply going to delete those box as well
and we need to have it open in there so let's go ahead to the front view and we want to
select those boxes holding the shift and click on those faces and let's go ahead to delete it
so now we have this basic shape if we use the tab key one more time to tap it and you can get it
back like this okay now we want to do the simple editing i'm gonna come in over here and choose
all the faces that i have and use the rotate command and rotate it a little bit like this
so now it's a little bit tilted there and again this is for the quick sketch so i do not have
a dimension in mind i don't even know what size this is but i just want to show you how to make it
now in this chair i like to have it symmetrical and it's hard for me to edit like right side on
the left side so right here on your subject tool you have something called reflect for this reflect
command will ask you like which subject you wanted to pick and then we will pick on this update and
then we want to have a y axis which is this green line is our axis so we want to click on y
next we're going to ask you which side you wanted to keep so i'm going to click
on the right side of the y-axis and hit enter you're going to see one size darker line once
one side is a lighter color so now we have this it means anything we do on the right side
it will be reflect to the other side so let's give it a try i'm going to pick up all the point right
there and we're going to pick up those points and maybe i want to be in the wireframe it's
easier for me to pick the point so i want to pick up those points as well all right for all this
point i'm gonna coming into the front view and i want them to be open a little bit so i'm gonna
select this open it and as you can see the left side will go with it so now i have an
opening arm right there we can take a look on the ghost view again and if you tap use the tab key
and you can bring this back all right so you kind of play around to get
the shape that you like maybe they need to be more of this shape like this so you won't
be all like this is a kink there and then you can keep editing until you find things you like
you can also um pick up the point like this like this can go a little bit higher
and pick up all of this this can be even higher so then you will get a little bit
more rounded there if you take a look on the um box mode you're going to see something like this
now i noticed this might be a little bit kinky kink over there so maybe i want to move this
out a little bit and this out a little bit something like that let's look at the the smooth
one more time with the tab key so we get something like that all right and then you
can keep edit until that you find the shape that you like maybe you want to have a certain part
is a little bit taller for example like this and you can keep changing until you satisfy
so i'm going to keep it like this and giving a thickness now it's only like a paper thin
right so we wanted to giving a thickness so we can print it out or we can assign a material so
we want to offset this sub d it's going to ask you which one i'm going to click on this one
and it's going to ask you like the distance on the top so on the top right here i'm going to change
maybe like eight kind of eyeball for whatever thickness that is and i want to solid i do not
want to have both sides similar like that you are doing the offset in the rhino nerve surface okay
and then we want to click okay then we'll get something like that notice that this is really
harsh edges there nobody want to sit in the chair like this it's really uncomfortable
so right here we have a remove crease command and it's going to ask you like what age so we want to
pick up the h that we wanted to remove and pretty much this is everything because it's a hard h
right now and then we hit enter now we'll get something really rounded now this is the fun
part how do we going to get it like a lot of a different type of a sketch first of all you
can pick up either the face or the curve or the point let's say i'm going to pick up these faces
and i actually want them to come out a little bit more and maybe i wanted to tilt it a little
bit more so we'll get something like this maybe i wanted to pick up these faces and because this
is uh almost like a symmetrical reflect that we have there so we can kind of play with it
to to make it into a very interesting form all right so now is the cushion in the middle now
if i want to pick up the cushion then i may want to pick up the faces for example those faces and
then i wanted to extrude them out something like this right so really quickly we already got that
cushion and you can make the cushion like just make them a little bit bigger like this
and you can make them hard edge if you want to right so this is a really fun part for us to to
keep tweaking now if you feel like the handle i want them to be more pointed you can actually do
like pick up those faces and you can like 1d scale it down so then they will be thinner like this so
it's a lot of things that you can play with all right at the end we just need a fee over there
so i simply just going to use the command in the rhino and we have something called truncate comb
and basically i'm going to do something look like this all right and i'm going to tilt it into the
angle that i like putting into here and try to move it into the right angle as well and we got
something like this all right and double check if it is too tall uh if it does you can trim it off
we also need to make sure this is actually flat to the ground so i'm going to use this curve
and we simply going to trim the leg off right and then we can simply just cap cap it and use the cap
command cap and always like to make them a little bit rounder so we want to use the fitted edges
we want to fit it for maybe one is fine as long as it's just
a little bit rounded so that will be one of the arm and i'm going to mirror to the other side
by typing zero and now i want to pick up both of them and again mirror to the other side
okay so now if you are looking for the combination or the different type of
sketch now what you can do if you like this and you no longer want to change it you can coming
back here and the reflect we want to cancel it so you just right click on the reflect
and uh pick up the sub d and right here on the top remove in six existing reflex symmetric
then we'll have something like this right simply just making another copy right there and for this
one we can say all right actually i wanted to have them flat on the top so let's all go ahead to pick
up all the point right there and using the gumball type it zero so we can make it flat like this
all right and then uh maybe here on the right here we want to make it wider i don't know um
just wanted to show you you can play with it really simply just the edges the faces and
also the point and those are the things that you can keep at it if you feel like okay maybe right
in the middle right here i need to have something bump up more like a pillow so we can use this one
for the h and kind of bump it this one up a little bit so that way you have a pillow over there
and again you can change the feed you can change the arm you can change a lot of things
and this is the quick way to do a quick sketch very organic shape for this example as a chair
i do have a chorus it's really detailed to talk about all the comments about the rhino 7 subdie
if you're interesting about the course please check out on my website there's a curriculum
in there there's a lot of course detail in there thank you for watching and i hope to see you next
you
