Create openings in building elements

00:04

in this video you'll learn how to create openings for stairs,

00:09

shafts and M. E. P. Element penetrations.

00:18

There are numerous methods to create openings and elements in your building model

00:24

on the architecture tab in the opening panel.

00:28

You can see several opening tools.

00:32

You can also edit the sketch of various elements and create openings.

00:38

Let's take a look at some examples

00:41

in this exercise file,

00:43

there's a building that has a stare that extends from level one to level two.

00:49

And if we look at the level two floor plan view, it appears that the stair is hidden.

00:55

But the issue is that we don't have an opening in this floor.

01:00

That's what we can do is add an opening

01:04

on the architecture tab in the opening panel,

01:08

click vertical to activate the vertical opening tool.

01:14

And when you do

01:15

it prompts you to select a floor, roof, ceiling or soffit

01:19

to create a vertical opening.

01:22

So we'll hover over the edge of the building here until we see the floor.

01:26

And then we can simply click to select the floor

01:29

and then rev it goes into sketch mode.

01:32

And there are several options in the draw gallery that you can use

01:38

and I'll use rectangle

01:42

and sketch a rectangle around

01:46

the stair.

01:48

And I'm gonna account for this

01:53

tread right here at the end

01:55

and then clean up my sketch here so that it forms

01:59

a closed loop.

02:01

And then I'll click finish edit mode.

02:05

And when I do I have now created an opening element

02:09

using the vertical opening tool

02:12

and I can go back and select the floor opening cut

02:18

and I can actually drag it to a new location if needed.

02:21

As you can see here, it's an actual element added to the model. I'm going to undo that.

02:26

And so that's the difference between adding an opening to the sketch of

02:31

the floor versus creating an opening element using that vertical opening tool.

02:38

Next let's create a shaft opening

02:41

back on the architecture tab in the opening panel,

02:46

click shaft to activate the shaft opening tool.

02:51

And then I'm gonna use rectangle again

02:53

and I'll sketch a rectangle here in this plumbing chase.

02:57

And then that's for the boundary line.

03:00

Next I'm gonna click symbolic line and then I'm going

03:04

to add the shaft symbol here by creating an X.

03:09

Across this opening

03:11

and then I'll click finish edit mode again.

03:14

And now I have created a shaft opening.

03:18

And so the difference here with the vertical opening tool and

03:23

the shaft opening tool is that when you use the the by

03:27

face or the wall opening tool or the vertical opening tool

03:31

is just going to create an opening in a single element.

03:34

Whereas the shaft opening tool will create

03:37

a vertical opening that will span multiple levels

03:40

as you can see there in the tool tip and it will cut through roofs,

03:43

floors and ceilings.

03:46

So if I open the default three D. View,

03:49

we can see that shaft opening has extended all the way through the roof

03:53

and when I select it, their shape handles to control the top and bottom.

03:57

Or I can adjust the top constraint

04:01

that is one of the instance parameters.

04:03

I can constrain the top to a specific level or leave

04:06

it set to unconnected and then specify an unconnected height.

04:12

So when I changed that,

04:14

I've now changed it where it doesn't cut through the roof but

04:18

it'll cut through everything else between the top and bottom there.

04:26

Okay next let's take a look at the by face. The opening by face.

04:32

I'm gonna go to the roof view

04:36

and on the architecture tab in the opening panel I'll

04:41

click by face to activate the opening by face tool.

04:46

And now I can select a specific face.

04:50

So if I select the face of this roof here rev it goes back into sketch mode

04:56

and I will use the rectangle option again.

04:59

Or in this case I'll change it to circle.

05:02

Let's say it's a a pipe or something that's penetrating the roof or even around duct.

05:10

And I'll simply sketch a circle and then click finish edit mode.

05:14

And when I do you can actually see a slight edge in there.

05:18

And if we look at the default three D.

05:20

View you can see that it is perpendicular to the face of that roof.

05:28

Whereas if I go back and we do the vertical opening option

05:33

do basically the same thing,

05:37

same size but in this case we have a vertical opening and then

05:42

an opening by face and so you can see the slight differences there.

05:46

So depending on what the situation is.

05:48

If you have a duct or a pipe that's penetrating the roof.

05:51

If it needs to be vertical,

05:53

you want to use that vertical opening tool or

05:56

if it needs to be perpendicular to the face,

05:58

then you can use the by face tool.

06:04

All right, go to a default three d. View here and take a look at a couple more options

06:11

back on the architecture tab in the opening panel,

06:15

I'll click wall to activate the wall opening tool

06:19

and now I can select a wall

06:22

and then rev it is simply just activates a a tool to sketch a rectangle.

06:29

There's no draw gallery. I simply need to sketch a rectangle

06:34

and I can sketch that.

06:36

And then I'll click modify to in the command and now I have another

06:41

opening element and there are shaped handles on each edge to adjust the size,

06:47

as well as various instance parameters to control the size of that opening.

06:53

And I can even drag it around as needed.

06:57

And one more thing. I'm gonna select that wall.

06:59

And then on the contextual ribbon tab I'll click edit profile and

07:05

now I have a draw gallery and I'll use the rectangle tool there

07:10

and I'll simply sketch a rectangle and click finish edit mode.

07:15

And now I have and I don't have an opening element.

07:18

I simply just have a wall with an opening.

07:21

There are shaped handles there so I can make

07:23

some slight adjustments to two of the edges,

07:27

but that is part of the actual wall.

07:30

So using editing the sketch that just edits the wall sketch,

07:34

whereas using one of the opening tools adds an actual opening element.

07:40

So depending on what you need, if you need to make additional adjustments,

07:44

you can use one of those opening options and we have rather large openings here,

07:49

but if we had some type of of exhaust fan on the side,

07:53

we could create an opening for a duct there and and we could

07:57

create this opening element so that we could adjust it afterwards as needed.

08:03

So once again several options there for you

08:07

to create openings in your building model.
