hello welcome back to the channel and
today's video is going to be a sketchup
tutorial on how to create a
dimensionally accurate 2x4 stud wall
[Music]
okay so um the idea behind this video is
you have i'm gonna pull up some images
an actual wall where you need to model
utilities going through it like piping
or electrical or anything like that
where you're designing and you need to
be accurate dimensionally
you have this kind of sandwich of half
inch drywall your 2x4 studs and then
half inch drywall as well that's what
you can kind of see on the left here and
you can see this open wall on the right
and this is what you would need to show
if you were planning things like
electrical box locations for either
switches or outlets
ensuring that there was an overlap in
between rooms things like that
so we're going to take a look at how to
do that in sketchup today and i'm going
to start with a floor plan of just 10
foot by 10 foot it doesn't really matter
it doesn't really matter what you make
the floor plan as long as you keep in
mind let's see that looks really small
is this 10 inches
nope 10 feet okay so it doesn't really
matter but the thing to note is if
you're going to add studs to this space
but you took measurements inside a room
then you want to start building it out
towards you so let's say you had a room
where it was actually inside the walls
inside finished drywall was 10 feet by
10 feet and you wanted to model the uh
the room beyond that well it's important
to note i'm going to use just this wall
but you can use whatever wall you need
it's important to note that when you
have finished drywall what you actually
have is a
10 foot
by one half
let me make sure i got the units correct
there 10 foot by
half an inch sheet of drywall
that's standard there is thicker drywall
but that's pretty normal for inside of a
house inside of a room and then you have
a 10 foot by three and a half inch stud
and then on the other side assuming the
other side is getting finished as well
you have another sheet of 10 foot by
half inch drywall okay and you may have
noticed when i put in the stud which
2x4 right that's the normal stud that
gets used in interior um in in inside
walls especially non-load-bearing walls
you'll get a two by four well um it's
important to be familiar with the fact
that those are actually one and a half
by three and a half inches dimensionally
because they get carved down from like
raw two by four so if you're working in
a house that's a hundred years old maybe
you have actual true two by fours but
anytime you're putting in modern studs
and it's two by four walls it's actually
an inch and a half by three and a half
you can google that i'm not lying to you
but okay so this kind of drywall
sandwich which again going back to the
images is what you have here that's what
almost every interior wall has is half
inch drywall uh three and a half inches
of wood and then another half inch
drywall and so we're gonna start
bringing this into three dimensions
we're gonna ignore the drywall for now i
just wanted it to be there to be clear
that like you do if you're trying to get
down to half inch
sizing analysis to make sure things are
going to fit wiring runs piping anything
like that
be sure to include the drywall because
it's there
so the first thing i'm going to do is
i'm going to grab my extrude tool the
little arrow pulling out of a rectangle
because right now we just have this flat
sheet
of our 10 by 10 room and then one of the
walls and another thing to keep in mind
if your room is 10 by 10 and you want to
model all four walls
you actually are probably going to want
to extend these
past the edges but we're just going to
do one wall for now
but right because it's going to be three
and a half inches well it's actually
four and a half inches once you add the
drywall in all directions so you would
actually want it to be 10 feet plus four
and a half inches on either side i might
do that in a future video this one's
going to be long enough as is
so this is your base plate it's the
bottom 2x4 that runs along the floor and
most of the time framers are actually
building walls on the ground and then
standing it up and so that's why they
would build it with a base plate and a
top plate
but that's a long way of saying we're
going to pull this up
and we're going to pull it up one and a
half inches so like we talked about
that's the size of a 2x4 and you can
kind of see
if you've dealt with two by fours before
this clearly looks like one you may
notice when you extrude stuff that the
back side of it can become empty and the
way you fix that is just grab your
pencil tool and any one line of the
hollowed-out shape just draw that line
again and it'll become solid
okay so now we have a two by four just
sitting on the floor where it would
actually go
and we're going to start putting in our
vertical beams so let's say you have a
nine foot ceiling height which is two
finished ceiling that's a pretty high
room but that's still fairly standard
let's just go to the corner where it
sits on the floor because that's not
gonna be nine feet from your base plate
that's going to be nine feet from your
floor
and we're just going to start drawing a
line up just to get our our dimensions
our size incorrect and let's go nine
feet okay
so now we have an arrow uh now we have a
line that's up nine feet and i'm gonna
put one on the other side as well in the
same kind of position
and that's just gonna kind of orient us
in the room so you can see
this is how high our two by four wall is
gonna go and so i'm gonna connect those
two and then i'm going to delete out the
screen that it kind of tries to make
but this should sort of show you the
general idea of how the outline of our
wall is going to look so let's start
dropping in two by fours to bring it
into the ceiling
bring it bring them up vertical
so this is going to be
3.5 inches and then 1.5 inches and you
can just drag until you get that correct
i think it's way easier to do 3.5 and
then the
quotation mark and then 1.5 and then the
quotation mark and that'll give you oops
that'll give you a 2x4
come on
well i said it was easy and then i'm
struggling but
3.5 comma 1.5
and then you should just be able to i
don't know why it keeps overwriting it
that should be all you have to do
okay
and delete all right so there we go we
actually get it's supposed to be pretty
easy any time you um drop anything
that's on like a finished rectangle so
here we made this enclosure with the top
um
i'll actually get rid of that top so it
doesn't happen every time i make a two
by four because that's that's gonna try
to close off the space um like we talked
about
so then i'm gonna just drop them on the
sides for now
and this will also be 3.5 and 1.5
and let's get our outer two studs uh
raised up so you are always going to
have a stud on the
or you should always have a stud on the
extremities of your wall
on the far left and far right it's
pretty hard to um finish drywall if they
don't have a solid surface at the ends
to anchor to
so you grab your extrude tool again you
pull them up to the nine feet which this
is where making those nine foot high
lines is really nice because we have a
finish point to extrude them up to
and just a little cleanup thing as
you're going you probably will want to
go to where you extruded and just draw
horizontal lines across your model
especially if you're trying to show like
individual studs where they'll start
where they're where they'll end
because a lot of the times you can use a
model like this as well for determining
how much total material you have to go
and get
so that's just my spiel there but uh
yeah so now we have okay the outer two
studs and that looks pretty good let's
do one um
stud on the top so just like we have
this bottom plate let's do a top plate
but let's do it a little bit differently
um let's take
right here i'm just trying to show all
the different ways that you could model
in a stud
so let's say you wanted to start at the
very end and just go vertically 1.5
inches
and then you want to come across to
right here and actually you can see it's
snapping it's got from point it's got
the lengths in the bottom right over
here and so you can see it just made it
just made the end of a stud and so we'll
grab that rectangle just like we have
every time so far and we're going to
drag it all the way
to this end point and it'll just snap in
place and so that was probably the
fastest stud we've made yet we check
that we don't need to backfill and make
sure it looks good but just zooming out
we have this rectangle
of our stud wall already going and now
snapping in the rest is going to be
pretty quick i'll show you how there's
this thing in framing it's um it's
called on center
and all that means is like it should be
a 16 16 is the most uh typical that i've
seen for interior walls is 16 inches on
center for your stud walls there are
some materials where it's actually
allowable you can go up to like 24 some
people will overdo it and do 12. some
exterior walls different areas code is
different but 16 inches is pretty normal
they say on center it's exactly the same
thing conceptually as on right edge on
left edge it doesn't matter it just
means if you are at the middle of a stud
and you go 16 inches you should be at
the middle of another stud
so that's that's me being long-winded
but for this first one since we're on
the right edge of a stud i'm going to
take a line from that midpoint make sure
i'm going at a right angle but i'm going
to go 14 and a half inches for this
first one
because just like we talked about right
a stud is one and a half inches wide and
right now i'm just marking where all of
them should start so i'm going to go 14
and a half inches and then from there on
i'm going to go 16 inches
and every time i
finish a line i'm going to go up and
down and then i'm going to go back at
the very end and clear out these well i
guess i'm doing it right now
and i'm going to clear out those marking
lines so this is just kind of my like
cheat for doing quick measurement i just
will put down a line
and i'll make it however long i need it
to be so for studs it's 16 inches and
then i just mark it
vertically i kind of make the crossing
line and then i delete out those
lines i use to mark it so i'm going down
this model and just every 16 inches
putting a marker in
and what you'll see is uh you're never
typically never going to be 16 inches
from both ends unless it just worked out
really nicely that you have a room where
you know it's some multiple of a foot
and a half or
a foot and a third whatever where it's
some nice multiple of 16.
so you can see right here all these gaps
are even until you get to the very end
we're a little close to the right
you could use that concept to
to design something that's not that way
but i'm just gonna leave it so so 3.5
1.5 and it's very normal that you're
going to have um 3.5 1.5 for all these
it's very normal that you're going to
have a not 16 inch gap on both sides
it's better to
leave that gap uneven than to make your
studs some
unusual spacing like you could say oh
well if i would cut all of the spacing
down to 14 inches i would get an even 14
inch gap here too
that's kind of incorrect because you
want your studs to be spaced at a
standard sizing i probably will have
some
diy in my comments like i do even
spacing all the time i don't care so
we're going and we're dropping in the
footprint of our
uh two by fours and then once they're
all modeled in here we're just gonna
grab that extrude tool and this part's
really satisfying
we just grab them we pull them up to the
bottom edge of our top plate which is
why we made that early
and we're going to do that for each of
them and it only takes you know a couple
seconds
and
you'll see like sketchup loves to snap
to things that make sense to it
so it'll give you oops ctrl z you can
always control z to undo just like you
can with the word doc or any other thing
um
and uh sketchup will usually snap to
exactly what you need to get to so there
we go
all right and um that's pretty cool uh
one thing that we do have is we have to
just come down and put a horizontal line
in across those studs you could do them
all individually it's way faster do it
this way and just delete out the panels
that it tries to put in
and now like we were talking before you
can see all the individual studs we'll
come over and do it for the other side
too
and uh if you're a builder just starting
to get into 3d modeling this probably
looks very familiar to you if you've
never seen an open wall and you're just
kind of getting into like interior
design or planning
then this is maybe new to you but this
is pretty much what a wall looks like
when it gets framed in and lifted up
so let's say that there's a door going
in this wall
because every room is going to have at
least a door and if you can do this
process for the door you can do any
window as well it's it's very similar
just a little bit easier in my opinion
so let's say for door placement
you were just instructed put it in the
exact center of the room
and let's say it's a 32 by 80 door which
is a pretty standard
interior door
okay so we're gonna just make a line
that's five feet just so we have a
midpoint reference and i'm going to use
my little cheat markers to say okay
that's the midpoint
you probably already had in this model
excuse me
in this model a midpoint marker if you
had gone with like this line
from the drywall that we put in but
that's okay we made a new one now i said
it was going to be a 32 by 80 door
here's where having some knowledge of
houses is important
when you do a rough opening which means
you're framing in a wall you actually
want to add two inches to both
dimensions for your rough opening
so
32 by 80 you're actually gonna make an
opening with your two by fours that is
34 by 82 and that's so that you have um
space for the trim like the
the door that gets hung on its hinges
and then put in frames that uh stop it
and have the little spot for the the um
latch
that takes up an average of two inches
and whoever's hanging your door is gonna
give you like okay well it's a 30 by 32
by 80 door
and um
a real framing person who knows what
they're doing is going to add two inches
to both of those for the rough opening
so there's my spiel about doors
um but let's go ahead and say from that
mid point that we made
that means we're going to add 17 inches
to either side for a rough opening
and then we're going to mark those edges
and then we're going to clean up
everything in the middle so we don't
need these anymore not really
and i'm going to put in the new studs
before i
uh before i
remove the old ones to show you what
we're doing
so
the um
right at the limits of where your door
is gonna go and i'll go ahead and put my
stud rectangles in here
right wherever your door is going to go
you're going to have two by fours to the
left and to the right of the rough
opening that's what they're going to get
mounted to but you don't always bring
these all the way to the ceiling they're
actually called jack studs
and you
house people on the internet can check
my terminology but
they just go to
the height of the door so if you think
about this the rough opening is supposed
to be 82 inches from the ground it's
sitting on a bottom plate that takes an
inch and a half of that so the height is
actually going to be 80 and a half
inches from the top of your
plate
so i'll extrude those real quick at 80.5
and then i'll talk about what we did i'm
gonna clean these up just like always
okay
and if we zoom out what you're gonna
notice if i grab my measuring tape is
that from the floor
to the stud that we just
dropped in
okay
um it is six foot ten and that's 82
inches let me make sure 72 82 yeah 82
inches okay so that means that we made
these studs at the right height for the
door opening and the reason you need
these to not go all the way up to the
ceiling
is
this also changes whether or not
structural i should probably put like a
disclaimer in here like i'm not
going to act as your licensed structural
engineer so nothing i say in this video
should be taken as absolute fact don't
sue me for anything but if this is not a
structural wall then you can just put
a flat one and a half inch
two by four on top of this guy
and you don't need to make it like a
beam that can carry significant load a
flat plate just like what's down here
will work if it's carrying any kind of
load or you're not sure
then what you should do is make a
little beam sandwich where you take a
two by four put it on side so it's it's
actually one and a half inches by three
inches
i'll just come in here and model it real
quick there's already a long video
so what you're going to do is you're
going to put a 2x4 on its side and
that's going to be this first inch and a
half
and then you're going to put a strip of
like half inch plywood or something
wood in between them
for 0.5 inches and then you're going to
put another 2x4 for this last
inch and a half
and you're gonna so you're gonna make
that little beam sandwich and it's gonna
be three and a half inches and you would
set it up here on its side
and that's how you would add like some
structural strength to it that's how
you'd make a mini beam i think it's
called a lamb beam
but if this is not structural you don't
have to worry about that so we're going
to model it this way flat bottom plate
we're going to extrude it we're going to
bring it all the way to the right edge
of our doorway and you don't have to
worry about these crossers because now
what you can do is grab your mouse tool
and you're just going to start deleting
out the elements that are in the doorway
and since we made our top beam already
we're not cutting out the stuff above
which is going to make our lives really
easy
which i'll show in a second
so just clear out everything you had
made that's now inside the doorway and
delete out these extra lines in your
header beam
delete delete
delete
delete
i'm not going to say delete every time
i'm not going to do it
delete and delete okay and the last
couple things you should draw in because
you notice your b your verticals got cut
off here so they don't look like two by
fours anymore go ahead and draw in the
feet
uh i don't know if it's the right term
go ahead and draw on these bottom lines
so that they'll fill in but i'm gonna
zoom back real quick so uh i'll clean up
these lines as well
but you see we just put a doorway in and
this is sweet but we have to add what's
called the king studs so those were
called the jack studs right the ones
that kind of define the doorway opening
the next thing we're going to do is
called the king studs but if you've ever
seen a doorway
you've probably noticed that you don't
have to step over a 2x4 to get into it
that's because both sides of the doorway
get independently screwed into the
ground
and
then we can go ahead and i gotta put my
bottom lines in there too
um
so if you did frame the wall you
probably did do one continuous piece of
wood across the bottom well once you
stand it up and
screw it into the floor or nail it into
the floor
you can cut out this middle point inside
the door because both sides are
independently mounted to the floor
and then the top plate is going to be
mounted to the ceiling so you go ahead
and clean that up and now you have a
doorway okay so that's pretty cool let
me grab my mouse tool again and get out
of here
oh boy there we go all right clicking
trouble okay so um the king studs are
what go right next to the jack studs but
they are floor-to-ceiling two by fours
so you this is pretty easy to model you
just come in right next to your jack
studs and you make another three and a
half
by one and a half
and you put that on both sides
and actually what's neat about this
there is exactly an inch and a half gap
between just the 2x4 that would have
been there on center
this gap's one and a half inches i
didn't plan it that way
some people some builders may just put
little blocks of wood in between these
two because it's kind of overkill to put
another two by four here so you could
put little um 2x4 wedges in here and
just screw it in three or four places
the purpose of this is so that your
doorway has vertical support all the way
floor to ceiling and it can't wiggle
side to side i also didn't mention it
the name of these things that go from
the top and maintain the 16 inch on
center um those are called cripples and
they go in above your doorway to
maintain the 16 inch on center spacing
which is important for like running
electrical or anything like that
so we are going to go ahead and put the
jack studs in be i'm just going to do it
to show that you need to have some kind
of
support here so this is called a
king stud it goes right next to your
jack stud and it runs from the floor to
the ceiling
and you're gonna
make sure that this is screwed laterally
into your jack stud a few places too
because normally for these studs you're
just putting them in the ground and then
you're putting them in the ceiling
there's also if you have a room that's
like above standard height so say these
were 10 foot or 12 foot ceilings
and if you don't want to worry about
getting like perfectly straight two by
fours or you're worried about warping
you can put cross bracing in here so you
could put little spacing two by fours
throughout this
and attach them horizontally and that
would kind of prevent side to side
movement we're not going to do that for
the purposes of this video but what you
can see here is we have kind of this
perfect structural
modeled wall showing all the two by
fours required plus a doorway um one
more thing that i wanted to do real
quick because we
made our drywall rectangles in the
beginning it'd be a shame not to use
them i'm going to go ahead and grab one
of them i'll grab this back one
and i'm going to pull that up to
the top and i really wish actual drywall
got uh frank got mounted that easily
but um
so i'm gonna take this doorway i'm gonna
click on the rectangle inside the
doorway and i'm gonna use my extrude
tool to punch it through to this face
and it just automatically cuts out the
drywall for that opening
so if i grab my measuring tape we'll
remember that we needed the rough
opening to be
what did i say 32 24 this is 34 inches
we're doing a 32 inch door yeah okay
perfect
and then we needed it to be 84 inches
high
no 82 inches high because the door is 80
inches sorry i'm getting confusing
myself it's been a long video
but this is perfect the last thing you
can do this is going to help yourself as
much as it's going to help anyone you
may pass the model to check and see if
you have any like straggler lines and
just clear them up because you don't
want confusion so lines like these that
are left over from
two by fours that we deleted out
anything like that make sure every two
by four has a base plate and then one
nice feature of sketchup uh you can go
into this materials tool on the side go
down to wood grab one that just kind of
looks plain doesn't really have to be
anything special
and just start filling in everything
that's wood and you can either leave the
drywall as white or you can give it a
special color if you're going to make a
legend that says like blue is drywall or
something you can do that
but this also makes your model like
really easy to understand so you can
take a look at
this model and just instantly know where
the different materials are
i pretty much always add texture to a
model especially if i'm showing it to
anyone else um or helping like a builder
understand like where things are
and it goes pretty fast because it's
basically just like paint it gives you a
little bucket you click whatever
surfaces you want filled in
i'm not going to spend too long making
sure i caught every little rectangle
oops
i maybe need surface there interesting
uh okay so we're just gonna go with this
because i'm at like a half hour video
already but um the next thing you could
do from this now is you could well you
could model in all four walls you could
throw electrical in here you could throw
plumbing in here you could throw
anything you needed to in here you could
model
ductwork and ventilation coming through
so that's the basic concept of how to
make a dimensionally accurate um
structurally correct 2x4 wall and i'm
not gonna pull it up because if you were
to just cover this
then like what would the point of
putting the two by fours in be
but you could pull like the drywall
potentially halfway up
just to show it is going to be a covered
wall
and then you could start layering it so
you could basically
give other people the permission to i'm
going to just undo that
you could give other people permission
to delete entities and view things that
are inside your model
but for now i think that's everything
you need in this video i hope you found
it useful if you are enjoying the
sketchup tutorial series be sure to let
me know about in the comments below if
there's something specific you'd like to
see in a future video let me know about
that as well be sure to check out the

with all the new stuff coming out um and
uh just be sure to leave a like
subscribe to the channel if you found
any of it useful it's a pretty new
