Creating a structural opening

00:03

The structural opening that we're going to create

00:05

will cut a void or a rebate into most

00:08

families.

00:10

The family will be face based and have a nested detail added.

00:14

The family would also use shared parameters which

00:17

would enable tagging and scheduling of these openings.

00:20

You'd also note by the graphics that we can show a pocket which

00:23

is a partial rebate into an object or in fact a full penetration

00:30

before we create our void geometry, I want to reference in a detail component.

00:35

The idea is, is if I place this on particular components and then I

00:39

ate this component or potentially look at this component in plan,

00:43

I want to either see the partial opening symbol or the full opening symbol

00:48

to do this. I'm going to nesting a detail component.

00:52

Let's go ahead and select the annotate ribbon

00:55

and on the annotate ribbon, select detail component

00:60

then reports to us that no detailed families are loaded into the project.

01:03

But would you like to load one now?

01:05

So we'll click. Yes.

01:07

And here we're going to pick mo

01:09

three underscore 02 underscore opening underscore DC

01:14

and then your version of rev,

01:18

you can now see that have a detail component on my cursor.

01:23

I'm going to place this down somewhere about here

01:26

and then I'm going to release the command by clicking, modify.

01:30

Now.

01:30

I want to make sure that this detail component is lined up to the same origin planes.

01:35

So I can select the detail component

01:38

and then drag that over these two origin planes and let go,

01:42

you'll notice that this then exposes two constraints and I

01:45

want to make sure that these constraints are then locked.

01:48

So that detail component is now anchored to the same

01:51

origin that my 3d opening will be anchored to.

01:55

OK. So we'll come back to the control of the detail component shortly.

01:59

Let's now create the void geometry required for our penetration

02:04

to do this. We'll go to the creates ribbon

02:07

and notice here we have our solid forms shown on this area of the ribbon.

02:12

But if you go to the void forms, pull down.

02:14

You'll note here, we have exactly the same set of tools, but these will create voids.

02:20

So here I want to use void extrusion

02:25

once again here, I already have the geometry for the void.

02:28

So I'm going to use pick lines

02:30

and on the options bar, I'm going to ensure that lock is selected.

02:35

In this case, I'm going to pick the reference planes.

02:40

Notice that the lines are now constrained to those reference planes

02:45

on the modify panel. I'm then going to select a trim extend to corner

02:50

and I'll pick the pieces I want to keep and tidy up the geometry.

02:56

I'll then go up to the ribbon and select finish edit mode

03:01

to make sure that the void is constrained in the front elevation.

03:04

I'll now switch to that elevation.

03:06

I can see the void has some gold geometry here.

03:10

So I'll select the void

03:11

and I'm going to just simply use the shape handle here

03:15

and then drag that down to the reference plane

03:17

and again, constrain it

03:20

and I'll do the same with the top.

03:26

OK? So if we now go into our 3d view, we can now see that we have the void and the solid.

03:32

What we need to do here is cut the void from the solid geometry

03:37

to do this on the modifier ribbon

03:40

on the geometry panel. You'll note here we have cut,

03:43

I'm going to select a cut

03:45

and then I'm going to select the solid

03:48

and then the void that I'm cutting from.

03:52

OK. So the void has now been cut.

03:54

If we return back to the reference level, I can now test dysfunctionality.

03:59

So I'll select family types

04:03

and here you can see that we have our opening height and width.

04:06

I'm just gonna change this perhaps to 36 inches

04:11

and I'll set this 1 to 36 inches as well

04:15

and then click, OK.

04:17

Now, what you'll note here is the 3D objects changed,

04:20

but the detail component has remained unchanged.

04:23

The reason for this is we need to associate the parameters.

04:28

So let's release the command by clicking modifier.

04:31

And in the project browser, we'd expand families folder,

04:35

then we'll expand the detail items, folder.

04:38

And here we can see our opening

04:41

if we now expand that and have a look at the type, I'm going to now,

04:44

right mouse click over this

04:46

and go to type properties.

04:48

So you now see that the original dimensions are set to 2 ft and 2 ft.

04:54

I'm going to now associate these parameters to the 3D family.

04:59

So here of course, the opening length is going to equal opening width

05:04

and the opening width is going to equal opening height.

05:08

And you'll now see that these are grayed out and associated

05:12

the equal button tells us that these are being driven by another parameter.

05:17

I also want to drive the pocket,

05:20

this controls the graphics in this detail component.

05:23

So again, here I'll associate the family parameter.

05:27

I'll need to create a new parameter here.

05:30

This is going to come from the shared parameter file.

05:33

I'll go ahead and select this

05:35

and note here we have one called pocket.

05:38

So we'll bring that one out.

05:40

This is going to be an instance.

05:42

And here I'm going to go ahead and group this under graphics.

05:48

Let's click. OK.

05:49

And OK. Again,

05:51

and you can now see our two D detail component

05:53

is driven in the same manner as our 3D pocket.

05:57

So let's now, go ahead and save the family. So we'll click, save

06:01

and here we'll call this one structural opening.
