Aligning walls with constraints

00:04

Our first objective is to align

00:07

the left hand face of the interior wall

00:11

to the left hand face of the exterior wall.

00:15

So if we now choose the align tool once again within the modifier panel,

00:19

top left of that panel and click on a line,

00:23

we can see on the options bar, we already have all faces enabled.

00:26

So that will suit us for what we want to do.

00:30

The first thing we're asked to do is select the reference.

00:33

Now the reference will be the face that will not move.

00:36

So if we click on here, we see this blue alignment line

00:40

which shows us that that's where we're going to move up to.

00:44

So the next thing we click will actually move into alignment.

00:48

So if we put our cursor onto the left hand face of the internal wall,

00:53

it moves into perfect alignment.

00:55

And we can see we have a padlock

00:58

which will invoke an alignment constraint

01:01

if we want it to. So it is optional. Whether we enable it or not,

01:06

we'll click on it

01:07

to lock it

01:09

and then choose the modify tool to exit the align tool.

01:15

What we'll now do is see what effect that alignment constraint,

01:20

that locked alignment constraint now has.

01:24

So if we were to drag this wall

01:27

to the right slightly,

01:29

we can see that that internal wall because it's locked in alignment

01:35

has moved with the external wall.

01:39

OK.

01:40

I'm just gonna undo that. So if I go up to the quick access tool bar and click undo

01:45

that will move it back into its original position,

01:49

we'll reload the align tool from the modifier panel. So if we click on a line,

01:54

but this time we will use two wall center lines.

01:59

So within the refer list on the options bar, we'll click on

02:03

what's already there and choose wall center lines.

02:07

This time, this upper wall here where my cursor is

02:11

will be the reference.

02:14

So if she,

02:15

if we zoom in slightly and click the center line,

02:19

that is now going to be the reference,

02:20

we can see that alignment line again there telling us that that is in fact a reference

02:25

and whatever we click next,

02:27

we will now be forced into alignment. So if we click on there,

02:31

we can see

02:32

that has now moved into alignment again, optionally, we don't have to select it.

02:37

We can lock those two walls into alignment.

02:40

So we'll do that

02:42

if we choose, modify,

02:45

select

02:46

one of these walls

02:49

and drag it, we can see

02:51

once again

02:53

they are forced to move together because of that locked alignment constraint.

02:58

I'm going to disable the constraints by clicking on the blue padlock.

03:04

And once again, we'll zoom out

03:09

and we'll use the align tool

03:12

in a very different way.

03:12

This time compared with the method that we've been adopting.

03:16

The method we've been using,

03:17

enables us to align and lock two elements into position.

03:22

But this next maneuver will allow us to do a multiple alignment.

03:27

So if I go up and click on a line again,

03:31

that will give us the opportunity to reconfigure the

03:35

way that a line works via the options bar.

03:38

And we will make sure that multiple alignment tick box is enabled

03:44

and that will allow us to align multiple things to a single reference.

03:50

Our single reference this time will be the center

03:53

of this right hand wall

03:56

and we can now choose each wall

04:01

individually

04:03

and they will all align

04:06

to that original first wall that we selected.

04:09

Again, you would have noticed that each time we clicked on the wall,

04:13

the wall to be moved. That is

04:16

we had the option

04:17

to apply a locked alignment constraint, which on this occasion, we didn't

04:22

once again, we'll exit the align tool by going up to the ribbon, a modifier tab

04:28

and choosing the modify command.
