Create and apply filters

00:05

in this video, you'll learn how to create a rule based filter

00:10

And more specifically,

00:12

you'll create a filter that can be used to identify interior walls.

00:18

You'll then see how to apply the filter to a view

00:21

in order to adjust the visibility and graphics

00:24

of the elements that meet the filter criteria.

00:35

To create a filter, switch to the view tab.

00:39

Then in the graphics panel click filters.

00:44

This opens the filters dialog.

00:47

As you can see there are two kinds of filters in rabbit

00:52

rule based filters and selection filters

00:57

in this dialog, you can create rule based filters

01:01

and adjust the filter rules

01:05

to begin, click new

01:08

for this filter

01:10

will name it walls, dash interior.

01:18

Then click OK to create the filter.

01:22

Now you can see the new filter

01:25

under rule based filters.

01:28

Next we need to select the categories that the filter is going to look at.

01:36

And for this example we'll select walls

01:40

and then we can define the filter rules

01:45

for this example, expand the parameter drop down

01:49

and select function.

01:55

Next

01:56

for the operator

01:58

will choose equals

01:60

and then we can expand the value drop down and select interior.

02:06

So now what's going to happen

02:08

is rev it is going to look at all of the elements in the walls category

02:15

because that's what we selected for

02:17

the category

02:18

and it's going to look at the function parameter and see if it equals interior

02:25

and if it does, then that element is going to meet the filter criteria.

02:32

Let's click OK.

02:34

And then we need to add the filter to the view

02:38

and we can do that in the visibility graphic overrides dialog.

02:44

Let's open the visibility graphic overrides dialog

02:48

and then switch to the filters tab

02:50

and then click add

02:53

and now we'll select the new filter we just created and click OK.

02:59

At this point

02:60

we can enable the filter

03:03

and then we can adjust the visibility and graphic display

03:07

of all of the elements Meeting the filter criteria.

03:11

For example,

03:12

click overrides under cut lines

03:16

and then let's change the color

03:19

to green

03:21

and then click OK to close each of the dialogues.

03:26

When we do we can now see all of the interior walls are green

03:32

and that's because the function parameter for those walls equals interior.

03:39

Let's go back and take a look at some other things we could do

03:44

on the view tab in the graphics panel, click filters again

03:48

and then let's select the walls, dash interior filter.

03:53

And now let's change the rules. Let's change the parameter to type name

04:04

and then we'll say the type name

04:07

begins with

04:10

and now with begins with we can't expand the drop down and select anything

04:14

because some of the operators such as

04:18

contains begins with ends with their more open ended.

04:23

Whereas if you select something like equals,

04:26

then rev it will give you the actual values.

04:30

And so just for an example here,

04:32

when we have equals we can see that some of the wall types begin with E

04:37

for the exterior walls

04:39

and some begin with eye. For interior walls.

04:43

So we'll set the role to type name

04:48

begins with

04:50

I

04:52

and then we'll click. Okay?

04:56

And really you shouldn't see any anything changed

04:59

because we are still indicating our interior walls.

05:04

And so the point here is that you can be very creative with

05:08

how you create filters and you can use them for several workflows.

05:14

And it could be for documentation purposes.

05:17

Or it could just be for quality assurance purposes to make sure that

05:22

you're using the correct wall types or whatever element types it may be.
