Hello everyone, welcome back to your PJ's CAD class. A YouTube subscriber of mine
asking how to use the construction plane. I think it is a great opportunity to
show you few features from a construction plane that may help you on your model
are you ready? Let's get started.
What its construction plan the construction plan represent a local
coordinate system for the viewport .So you can see there has three direction
for x y and z, sometimes it represents for U, V and W. If you look at the Rhino
construction plane that you're going to see this a red line and this is the
green line, and it is showing the X axis and y axis. if you go to all viewport and
then, for example you're looking at the right view then you are looking at
the z axis for the green, so how do we use the construction plane? let's say I
have a ring here, and on top of the ring there's going to be some sort of the box
design on top of the rings. I'm going to move this on the top right in order to
work on this box, in this box only. I may need to move my construction on the
surface about right here at this surface. So I wanted to do is to go to my
construction plane you go to that little triangle icon there, and then you have to
set it to the object and then you can pick up the object, then your
construction plane is right now at the middle of that top surface, so from there if I want
to start with something. Let's say I want to draw a line, and I can just type it 0
and you will snapping into that area. Let me change the color, so it will
snapping into that area. so I can draw a line starting from the center you can
also change to any place that you like on that specific on the red box so let's
go ahead to set origin, and then lets set it right here at the endpoint so
now if I want to draw a line for example I want to type at 0 and you will
snapping into that zero point and I can draw a line right there.
At any point that you reset the construction plane and if you wanted to
go back. You can go to either go back to where we were or you can go into here
there's a tab it's called "Cplane" and then right at the top you have to set
the Cplane "world top" then you can have it go back to original one. Okay so this
is one way to use to change the construction plane, and other things you
might see already there's a design right there. It's a three circle cut out
design. Let's say I'm going to do a design similar like that and then I'm
going to draw that three circle on the side so one, two, three, and then I want to
trim it like this, and join them together. Alright so then I have that design
right there. So the way to do the design, I can move this design to the front and
extrude it, so that's go to "solid" -"extrude planner curve straight". We can
extrude any length, we move the little piece out, now, if I'm going to
"Boolean difference" this guy out of this guy and... see.... this is not much of a
difference but you kind of also see.... the one I have on the right is the same
distant both from to and the bottom. The one on the left, right here at my perspective (view),
it is a little bit thicker or deeper on the top and it's thinner on the bottom.
It's because this area is tilted. it's tapered down to the bottom. So in
order to do that I will need to.... let me go back to what I did. Before I do
anything on that, I actually need to set my construction
plane along with this tilted surface, so the way to do that we actually need to
come in here under the Cplane again you have the one is called set Cplane to
the surface right. So we're gonna click on this surface and it will ask
where's the zero point is, we're gonna click up there and giving one of direction
for X (axis), so if I kind of rotate it you'll kind of see now my construction plane is
you know the same with that surface, and what we're going to do here is we gonna
draw something again like three circle here, and then I'm going to trim it, and
then join them there. So now if I move this one to the surface or where I
wanted to have a cut out, you will see it is really flat to the construction plane
and then we can do "extruded planer curves- straight" in this case and then if
we do "boolean difference" so that will be equal distance in all the way all right
so that's the way to use the construction plane and then if you want
to go back to where the original you just go to set the Cplane which is
construction plane "world top" then you will have it back to the original one

my video to help me ranking on the YouTube so I can create more free
tutorial for you. Thank you for watching and I hope to see you again next Monday
