Hello everyone, Welcome back to PJ Chen Design channel. Let's talk about
the very interesting commands called "tween curve" and how to create this very
interesting organic form. Let's get started.
Let's start with the front view. We are going to draw two lines here, and I'm
gonna turn on my Grid Snap. I'm going to do a line approximately going like this
up and down. Okay and the other line, I'm going to do is in the opposite direction.
I will go down first and I will go into the top. It's kind of pointed
figure 8 shape there. So with those two lines, I'm going to make a little bit
distant to separate them in between. Alright. Now, if we want to create a
surface. We could just LOFT it, and what we are going to do is go into the loft
command and you have from here to here , and then you get this really straight
surface right there. I'm just gonna put it there for the comparison.
The command we are going to use is called "tween curve", so you type it
t-w-e-e-n, tween curve will show. and then I'm going to just start, this is
star. this is end. And you will see the line there. Now on the command bar, it will
ask you how many pieces do you want in between. so right here I have eight we
can do it more or less, and I'm just going to keep it eight.
so then it will automatically generate this curves from that to that
evenly out for eight of them. Okay so why am I need to have this as a
comparison. If I'm going to do loft again and then I'm going to turn... make sure my
Record History is on, and I'm gonna select all those curve over there, and
I'm going to LOFT it. And then what is different than the first one
there? you can see the curve we have instead of straight going down
it has a little bit curvature right there. and since we turn on the history
and we have this curve in the middle, so for example, I can turn on the control
point and I can keep editing, and my history will follow okay. so it's a good
thing to have the history on as you can always see the changing love. but
this is not what we are looking for there so I'm gonna go back one more step
here. Okay we have all those curves I'm going to select all of them, and I'm
going to extrude into the surface first. So let's go to surface-extrude surface curve-straight.
Make sure we want only one side. We don't need both sides, and I
want them to just touching edge on the next one. so that's how we get this surface
right there. Let's go to the Surface and we have Offset Surface. Let's do one
first and see how it goes. We gonna pick up this one, and then you
can set up the distance. I have a distance here for one, and you can flip the
direction if you like it goes into the other side. So that's how you get the
distance. Now let's do all of them at once. Their direction are going to the same
way, so I'm just gonna click OK. then I will get this very flowing interesting
form there. and I'm gonna move this on the side for the comparison. Let's go to
the top view and we are going to create 2 closed curves. They are pretty
organic. It's going to be like this, and the other one is possible it's going to
look like this, for example, and let's go to use the align tool, and align to
the center, like to the zero. Okay so in the perspective view, we are going to
move one of it up to whatever desire height over there. And we're gonna use
the same command "tween curve". Pick up the start
the end, and then you are going to see something like this. You can kind of
moving the point or click on those point and for them to align better in the way
that you like. You can kind of play around it so once you have that we can
do the same thing. But this time, since this is a closed curve, we're going to
turn it into a solid directly. Let's go to the solid, and let's kind of
moving up a little bit. It's more like the building then you have a different
floors. You can do the same thing like this. Okay so one more things I wanted to
show you here. What if I make this shape and realize I want them to twist a
little bit more. Okay so we could use the twist command but I want to show you the
difference by twisted right now or twist before you extrude. So let's go to the
twist command. Let's snapping the axis to the zero, moving to the front
view. I'm going to hold my SHIFT and click. Coming back to the top view, and
I'm going to click on the top view, and kind of twist maybe 180 degree right
there. Okay so now we see this shape and I'm
going to keep it keep this one as a comparison. so let me go here to select
the polysurface that we just did, and deselect those. Let me move this on the
side. Okay so now we have one for the comparison, I find the original one
before we twist. Then we want to go to the twist command, before we turn it into
the solid. So let's go to the "twist". We're gonna snapping into the zero the same
like we did on the previous one and we're holding the SHIFT, click. Go back to
the top view, click, and click 180 degree. Okay so notice that what I was twisting
is the curve instead of this surface, and they are in the same
right now, so let's go ahead to turn them into the solid-extruded planar curve-straight
and I would like to make them as close to the one that we had
there. So let me turn off the Osnap and something like this. Okay the shape is
twisted but in the way I'm twisting the curve, so I can maintain a wall is still
straight. This one the wall is twisted on the side. It's not really a preference
but if I'm going to 3d print, and turn this one on the left to the mesh, it will
make my model very complicated but it really depends on what you're looking
for if you want to have the wall is straight, but just the form twists, or the
other way. okay I hope you enjoy the video please
