Autodesk 123D beta 9 Sketch Planes - Press - Pull Video Lecture | Autodesk 123D: A Complete Course - Design Softwares

let's look at this sketch planes and
push pull tool so let's start by
creating a primitive notice how we've
got our three planes so it's very
important that you understand that we
actually draw on any particular plane
that you choose so I'll draw on my
bottom plane like so I'll extrude it so
say I wanted to cut a hole from this
space will add a window I could go and
go to sketch get a rectangle and I could
draw my rectangle I could then go to my
push pull tool or press pool click on it
and then I can just drag it all the way
out press ENTER and I there you have it
you've created a hole through your
object and I can do that again on the
other face I can do it this time with
the circle and I can go press pull all
the way through press Enter
and then you've got circles going on
each side and then square on the other
side so there's no problem when you're
doing when you've got flat faces to work
with but what about if we had a cylinder
so i'll create a cylinder let's say we
wanted to cut out a square window from
the side of the cylinder get my
rectangle tool it's not letting me
because there isn't a straight surface
to work with so this is where it starts
to get a bit more complicated and we
have to start considering about sketch
planes so if we select the cylinder till
he goes blue notice how i get a pill
that appears here now you want to select
the right hand side little icon and
scroll down to plane if you click on
that notice how if i change my view cube
how there's a there's a sketch plane
that's been created and i can click
enter now if i go to sketch new sketch
and i select the plane that i've just
created and then i make a rectangle I'll
use my view cube to just rotate a bit
there you see I've created a rectangle
almost looked like in midair but because
I had a sketch plan that allows me to do
so without the sketch plane there's no
way you will be able to actually draw or
cut into this so now if I select my
rectangle I then go to press pool
and then go all the way up notice how
I've added a rectangle that's going
through my cylinder if I wanted to cut a
window from that then I would need to go
to extrude select your square go all the
way through notice how now the pill has
a lot more features so you can actually
choose to join this rectangle to the
cylinder or you can choose to cut or you
can choose to intersect intersect so in
this case we want to go to cut
and see how it goes transparent and if
you click enter now we've got a whole
going through our cylinder so that's
really important that you create sketch
plans the only negative is that for a
sphere if you try to do the same thing
create a plane the sphere is the only
object that we won't allow you to create
a plane on the sphere unfortunately so a
way to get around that is if we use our
3d rectangle and what we want to do now
is if we click on this surface and then
now we go to the pill appears and then
we can go to plane and let's create some
planes that are offsetting from the cube
so we'll click on now the side the pill
appears go to playing again let's move
the plane out away from the cube I'm
going to delete this for the sake of the
exercise
no it doesn't want to delete all right
no worries we'll just use the other side
of this so we'll go on here peel appears
so select the face select plane let's
move the plane away from that so now
that what we've got there is is is we've
got three planes that we've created now
if we go to our browser notice how we've
got three components so if I turn that
one off we've got the cube got the
cylinder and our sphere that we had
created so if we want to delete
something we can you can either turn
that off or you can right-click on it
and completely delete it like so let's
delete this cube as well because
actually let's just turn it off for now
now what we can do is is we can place
our sphere within these planes that
we've got so if we get a sphere right
smack bang in the middle of this like so
let's say now we want to get a circle to
cut straight through the sphere because
we've got our planes there as you can
see this is work plane too so now I can
actually go sketch new sketch i select
work plan to I can now draw myself a
circle I'll use my view cube notice how
now
circles in midair I can now select my
circle select extrude and what I'll do
is I'll make it go all the way through
you notice how it's going all the way
through now I've got my pill option that
appears again here you can it's asking
us do you want to join you want to cut
do you want to intersect so in this case
we want to cut so now you'll see that
we've got a nice hole going straight
through it now let's create another
sketch just for fun let's pick one of
the other ones we've selected let's draw
more of them interesting shape like so
now let's select this let's extrude it
and let's make it go all the way through
again the pill appears we can go to cut
hit enter and then now notice how we've
managed to cut straight through this
fear so the key is is if you've got
something that's really a spherical very
organic no straight faces whatsoever
it's important that you preempt that and
create yourself create yourself a cube
and then
select on all the faces that you think
you'll need so in this case we'll select
on this face go to the pill go to plane
and just make sure you just push the
plane away from your cube go to your top
view and then push it away and then what
you can do because we no longer need
that cube we only used it to create our
planes you can either choose to turn it
off or right-click on the component and
click delete and there you have it
you've got your planes ready to go in
case you do need them hopefully you can
sort of have a play with that see how
you go and keep practicing
