1. Introduction: If you feel intimidated by all
of those super long multi, our tutorial videos on rabbit. I have created
something just for you. As you when I was learning
rate which I couldn't find any information that
would be more digestible. So I have decided
to do just that. Hi, my name is Matt
Jay and I have made this course aimed
at advanced users. We will focus on only one
topic and that is floors. We will talk about
everything there is to know about floors and
we will go in depth. I will share with
you my personal tips that I have learned by working as an engineer mostly on late stages and
phases of projects. This course is for those who have prior experience
in Revit and want to get the
most out of it and really unlock the
power of the program. At the end of this course, you will get the knowledge about the tools and their
actual usability, about the limitations
of the program and how to overcome them
if that is possible. So let's get started.
2. Sketching tips: Sketching tips. Okay, so first if
you want to create the floor by sketching
the boundary lines, and if you leave
it like this open, you cannot finish, you
will get an error. That line must be enclosed
loops. Here it is obvious. I can see that I have
a gap here and I can finish it or close it. But let's say that I
have a sketch like this where on the first side you can not see that
it's not closed. If I try to finish
it, I get an error. And I can see here with this orange dot that
where is the problem? Another thing, How
to see this tab? Select the sketch lines. I can see that here I have a
blue circle which is empty. That tells me that these
two lines are connected. Here. I have a blue
dot which is full. So this one tells me that these two lines
are not connected. If I zoom in enough, I can see that they're
actually not touching. Never just correct it. I can see that now I have a blue circle so I know
that there are touching. And if I want to finish
this sketch, I can do it. Another thing that happens
to me when sketching is that let's say that
I have a floor like this and I'm
modifying it a lot. And something like this happens. I have overlapping lines. Also. It highlights where
is the problem. So I can just go select
all of the lines and see, okay, I have two
of them in here. So I need to delete one. So either I would go like this and trying
to find the line, or I would select the language
I can see, delete it, and then I will let
it with another line, which I can correct
and I can do it. The thing which
happens to me a lot is that when I'm sketching
and I'm modifying the floor, Let's say that this floor
would have a sketch even here. And something like this will be left there
and I'm zoomed here. I check the finish,
I get the error. Line must be closed
loop at jagged lines. Therefore, there should be four. I select. I see here of
course they are connected. So where is the problem? Sometimes you just need to
zoom out, try to do it. And now it has
highlighted the line which is outside
of this boundary. Then I can select it, delete. Now I would be able
to finish the sketch. Okay, the second thing is about creating
openings in floors. Let's say that I could
do it directly in the sketch mode that this
would represent my opening. Then when I want
this opening to be like directly above one
another in all of the players. I don't have to sketch it
in every single floor, which is quite time-consuming
and diverse fingered bow. This is that this floor, or if this opening will
move in this floor. I have to move it manually
in all of the floors here. And you can imagine that I
can easily forget to do it. So shafts, I prefer to use
Daft opening tool here. Where you create the opening. You can even create the
sketch symbolic lines for the opening like this. And I will set the
constraints from level one to level six here. Now, in the 3D you
can see that it is cutting floors
directly above them, like one above another one. Here, I can be 100% sure that
it is in the same position. The best thing about it is
that if I need to move it, let's say like this, or in a floor plan that I will have to move it
from here to here. I can be sure that it
will move in all of my floors the same. So the mistake or the
possibility of mistake is much, much lower than when
creating it with the creating opening
with sketching. Then there is a
thing to consider that sometimes you
want to shaft opening, sometimes you want to
directly sketching. And one example is theirs. And let's say that you are not creating stairs
with the Star Tool, but you are creating blending with another floor like this. This would be my main landing. Then I voted some
families for stairs. And let's say that
I want to create this opening with the
staff to if I would do it, the child would cut even the lending or even the floor which
represents the stair lending, which I do not want to be cut. I want this flower to be hall, and I want only this one to be cut with the shaft opening here. If I choose AnkG good geometry, I cannot actually do it. I can, I can not tell
it not to cut my floor. So in this example
or in this instance, I am using sketching the opening directly in
the sketch of the floor. So me personally for stairs, instead openings, I'm using
directly sketch for shafts. I'm using the shaft opening
to then the last tip for sketching is dividing
a floor into two floors. Let's say that I will have some complicated
overflow like this. I need to divide it
here to the middle. So I could delete this and
create it from scratch again, we just time-consuming
or I could just select the things, press X. Then I would close this one. Finish. And I would create
similar with the shortcut C S. And I will just passed
a line to current view. And this will pass my
previously cut boundary lines. Then I will just
close them, finish. And I have floor divided
into two separate floors.
3. Do not model floors with other categories: Modelling of floors or ceilings. Why you shouldn't do this? First and foremost
reason is that floors are offsetting downward
from the reference. And rules and ceilings
are offsetting upwards. So here I model the floor. We are in the section view. And you can see that
it's on the level one. This line is
representing my level. And you can see that it is, it is offsetting
downward 150 mm. Here I have a roof which is
also based on the level one, and you can see that it is
upsetting upward 125 mm. If I change. Now the thickness of this floor,
let's say 150-300, it will move in this direction
downward and it will remain the top reference
On the level one. Whereas on the roof, the reference is based not on the top surface of this roof, but then the bottom
surface of this roof. So if I changed
the thickness from 125 to something different, it will move upward and retain the
reference on the lower, lower part or lower
face of the roof. So let's see it in action. You can see that it
moved in this direction. And what is the
implication of this is that let's imagine that you would model a
roof with this floor. So you would have
something like this, which represents
the concrete slab which is holding these roof. And let's say that I will
change the route 300-150. Again, you can see now that I have a gap here which
shouldn't be there. And I have to go and manually
move the floor to be again, like clean a nicely sitting
on the concrete slab. On the other hand, if
I would go 150-300, you can see now that
it is overlapping. And again, I would
need to manually move the floor up to clean it. So if you are doing
something manually in there is higher
possibility of making a mistake because you
can always forget about correcting
something manually. So if you use a roof for this, you can see that if I
change the thickness, I do not have to
worry about this. And also on the other side, Let's imagine that
I would model floor with the roof or
the ceiling which I have seen modeled ceilings. Now, if I will change this
thickness, 400-125 again, you can see that now
I will have here a gap with I would
need to manually move the correct because I need this level to be
on the topmost part. That is why you shouldn't
interchange modelling of the categories with
different categories. Let's say floors, roofs are
ceilings and vice versa. The next reason is
also scheduling. Let's imagine that I have
a floor schedule here. And if I modelled
my rules explores, I would need to
know and remember and make some parameter value, which I could then use
to filter the schedule. So I would know that my roofs, which will be
modeled with floors, will be filtered away
from the schedule. And the last thing is
interchange of information with other professions was
imagined that I would have to export IFC model. And I would make
this with floor, but it would be actually roof, then in the IFC would
be marked as floor. So the cleanliness of
information and the exchange of disinformation with other
people would not be that good as when you are using
right category for this.
4. Defining slope: Defining slope. So we have more tools in rabbit how you can define
slope or the floors. One of them is here,
the slope arrow. You just sketch the slope arrow. And you can define
the flow by height, a tail, and head to head. Let's say that here I will have zero and here I will have 500's. So I know that at the tail, I have zero, at the head, I have 500 and these will
define me the slope. So let's go to the view section. You see that here
I have zero and here at the end I have 500. So this made the slope. The another possibility
is to change it from the hate at tail
to slope directly. And here I could
just write my slope. And let's say that I wouldn't
want it in percentage, but in degrees, I would need to go to Manage project units. And here under the slope
can change percentage two degrees or
whatever ratio I want. Usually we are using percentage, so I will have it on per cent. Now, if I will just close it, you can see that I have
a slope of ten per cent. The good thing about these, then you have a parameter here. So I don't have to go again
in the edit boundary and in the sketch mode and do it like
all fruit the slope arrow. But I could just write it here, five and it will change. You can even make it negative. We didn't go into
other direction. There are some
situations when it is better to use
the slope borough. And one of them is that
imagine the dislodge wouldn't be perpendicular
to the edge of the floor, but it will be
sloping like this. Now it's better to use
the software because with other methods you cannot
actually do it well. Or if the slope is
diagonal like this, you can see that it's
sloping in this way. Or, you know, like on the specific points,
let's say here. And here I have two
points which I know will define my slope or
the whole floor. Then I can use this slope arrow. And I would say that at
the tail it would be zero, at the head it will be 500, and this would create a
slope for the whole floor. The next tool is to define solve directly
by the boundary lines, which is the property
of the boundary line. If I would select it, I could check here. Defined slope. And now
I can define slope, let's say ten per cent. And you can see that it is
sloping in this direction. Here, this little
mark will indicate which of the boundary lines
is used to define slope. And with the floors, it works like this that
if I'm defining my slope, the positive value here, ten per cent will going downward
when it hits the floor. You can see that
this is the level and it's going downward. Whereas with the roofs, if I do the same thing
that I have over here. And I have also ten per
cent on the boundary line. But the positive In the roofs is actually sloping
it upwards and downwards. So I would like to
define the same slope, the same direction of the slope. I would need to put here the negative number and then I would have it same
as in the floors. This is one thing to take a look at or to think
about when defining slope by the boundary lines have undefined slope by slope arrow. I don't have to worry about this because the sloping
direction will be directed by the globe
arrow direction. Then the last of the
tools which are here represented are using
boundary lines, which is called
parallel sketch lines. And it works like
this that you can, you can select two
parallel sketch lines. Say that it defines
constant hate. Then you can say that this
one will be at the head zero and this one will be
at the head, let's say 500. And you can see that it
would create a slope. Basically, what it does is that here on the beginning
boundary, I have zero. Here at the end boundary
line I have 500. So it's practically the same
as using the slope arrow. Me personally, I never use this, but I have seen it being used. And then if you have
the graphic like this, you wouldn't be surprised
at what it means. So we know that is
useful to define slopes. Then there is one
thing that floors can have slogan
in one direction. So let's say that
I would like to make a floor which would be downward sloping like
this, like a roof. And if I try to do it
with the slope arrow, you can see that I
can actually draw another slope, slope arrow. And if I want to do it with the boundary lines, I can do it. It looks like I can, but if I tried to finish
it, I would get an error. So what does this mean is that
you have to actually model separate floors for every slope. Or we would have to use shape editor to
be able to do this, which we will take a look
on in another video.
5. Shape editor: Shape editor. Okay,
so the next tool, how to create slopes in Revit
is the shape editing tools. These tools is great
if you need to create a floor with more slopes. Let's say that I would
have a floor drain here and I would need to slow my floor like this in four
different directions. If I would like to do it with the tools we discussed
in the previous section, I would have to create four
different floors for this. But with the shape
editing tools, I can do it only we do only
with just one element.
6. Slab edge: Slip edge. So basically you can imagine slab edge images here
under the floor. Slab edge as a profile that is swept along the
edge of the floor. Let's imagine that I have
a profile like this one. The L or profile like this
one, rectangular profile. And I would sweep them along
the edge of this floor. So here I have
created a slab edge, which is L 100 127. You can see here that I
have this profile used. And if I go to 3D or a floor plan and I would
select a slab edge. You can see that it created an element
which is this profile. Along the path. Here you can do some
modifications to it. Let's say you can flip it horizontally,
flip it vertically. You can use some offsets to position it more
correctly or even angle. So you make sure that it is
the way it as it should be. So where would you use this or what would
you use this for? Me personally, I use it e.g. for the termination profiles,
termination steel profiles. In examples like this one, Let's imagine that
you have a room, you have a floor, and then
you have opening here. And if you imagine that this
floor is from concrete, then it would spill
over this edge. So you need something, some still profile at the edge of this so it
will not spill over. Do it like this, that I'll adjust the
floor slab edge here. And now in this section
you can see that I have actually
the profile here, which is holding my floor. So this is some moral, one of the possible ways
how to how to use it. Me personally, I haven't
used it for anything else. The good thing about
this slope edge or the slab edge is there. You can even use the
hollow profiles, which is not possible
with some other tools like both VBS or railings, if I remember correctly. So let's imagine that I will use this another profile and
you can see that I use the whole profile on this slab edge and it
looks something like this. So let's go back to
my L profile. Okay. There is one problem with this slab edge that let's
imagine the divers slab that is sloping like
this. Let's say 10%. And now I would like
to put a slippage on this edge which is sloped
and use like this. You can see that
there is a slope. And I want to place a slab edge. And this edge of the slab, I can do it on the
horizontal one, but on the sloping
one I cannot do it. There is one trick
how to overcome this, and that is the dude,
remove the slope. Then you would place
the slab edge. Now, if I apply a slope like this. Now you can see that the slope which is still there
and is sloped. The good thing about slab
edge is also that is, it is connected to the edge. So if I move the edge, the slab edge will move with it. The next good thing about
the slippage is that you can create separate slippage
schedule like Here. You go to new schedule
under the floors. Here, you press the plus button. You have slept edges. And you can just use, let's say type mark. And the good thing is that
you can schedule linked, but also volume, which
is awesome possible in some different
things like this. Let's save all sweeps, if I remember correctly. So here I have a mark, length and the volume. So this is basically
the thing that you need to schedule this properly. Once super big disadvantage of the slug veggies that you can actually take it in your sheets. So if I try to use normal deck, you can see that I
cannot, cannot get it. And even if I use
multi-category take, I cannot get it. I can take it. So that is making this tool
practically unusable. But there is a work-around that if you create
the assembly from these, let's say like this slip edges. And I would put my mark
into the assembly. So now the tide mark from
the assembly is the same as the tide mark of this profile. Here you can see that
I have a type mark 01. In this assembly. I have also tide marks at 01. Now because I can
take assemblies, I'm able to take this profile. This is a work around
how to be able to take and slip edge in my feet. So basically me personally, I use it a lot. I only use it for things like the termination
profiles, the floors. And if I need to take it, I would create an assembly
and take the assembly. Sometimes I would prefer just to create another type of family, which is almost the same. But I can take it e.g. generic model family.
7. Bonus tips: Bonus tips. So the first is the floors show even
when they're outside of the view range up to an
additional 1,220 mm. And we can see in this example that I
have a floor plan here. My view range in this floor
plan is Toby is 2,300, cut plane is 1,200
and bottom and view depth is under zero
from the level two. So if I go to this section, you can see that this
represents my view range. And bottom and the view depth. Nereid, the
additional visibility of the floors threshold, which is 1,220 mm. And you can see that my floor, this one is actually outside of my view range
of the floor plan, but inside of these thresholds. So I can still see
it in my floor plan, even though it's
outside of the range. If I move this directly
on the threshold, 1,220. Now you can not see it. If I move it 1 mm
app, you can see it. So this is an
additional threshold, which is there in the rabbit. And you have to think
about this when working. The next thing is the
thickness of the floor. You have more of
weaknesses here. You have instance
parameter thickness, which is not editable. Then there is default thickness, which is also known
as the devil. But the special thing that happens is that
when you are using the shape editing tools and
you have infrastructure, some material which has
variable thickness. Then after you use the
shape editing tools, you can actually manipulate
the thickness of the floor. And what it means is that
I put here number 5500, then I would get
it uniform height. So everything will
move to 100 mm. Or I can just leave it. 300 is in worse
shape back to 300. The thing about this
thickness is that it is not, you are not able to schedule it. So if you do it this way, you won't know what
the real thicknesses. Let's say that I would create modified element 500 mm thick. Then I would have no way
to know in the schedule. Let's see floors. The you can see I have
curved thickness. I have different thickness. But for the thickness as this, I don't have anything. So what I can do with these, these ways is to calculate
the thickness actually, or you can even use
this for, let's say, that I have a floor here
like this that was modified. So I need to find my
average thickness. So I can do this in
the floor schedule. Sorry. I can do this in
the floor schedule that I would use
other parameters. And here I will use mark. So we will know
which blurry this because I put a number one
in Mark of this floor. Then I would use volume
and area of the floor. And I would use
calculated parameter, which we will calculate
the average thickness of this board from the
volume and from area. So I need to put here length. Then I can go volume
divided by area. And I will get average
thickness in millimeters. So now we look at this. You can see that this is
my floor mid mark one. And you can see that it
calculated that it has average thickness of 350 mm. So that's how you can actually get this information
from your model.
