Create shared parameters

00:04

Let's begin by creating a new project

00:07

on the home screen, select new

00:10

and for our template file, I'm just going to use the default structure analysis

00:14

and click. OK.

00:18

This project is purely gonna be here to

00:20

host our structural foundation and test it out.

00:24

So now that our new projects has been created,

00:27

let's go ahead and create our new family.

00:29

Go ahead and select the file ribbon

00:31

and then pause over new

00:34

and then select family

00:37

in the new family dialogue box. We're going to begin by using generic model dot RFT.

00:46

So before we create our shared parameter files,

00:48

what I'd like to do first is introduce you to built in parameters within rev.

00:54

If I go up to the create ribbon and select family types,

00:58

you'll notice when we choose generic model by default,

01:01

we just have one built in parameter here called default elevation.

01:05

We also have some others under identity data,

01:08

but this one here is a dimensional value.

01:11

Let's now go ahead and click, cancel.

01:13

And what we're now going to do is change the category of this family

01:17

again, on the create ribbon, we'll now select family category and parameters.

01:24

Now initially here, of course, we started with a generic model template.

01:29

So of course, the category is set to generic models.

01:33

Our intention of course is to create a structural foundation.

01:37

So I'm now going to change the family category to structural foundation

01:41

and click. OK.

01:44

If I now go back to the create ribbon and select family types, again,

01:49

notice here that we now have many more parameters created for us.

01:53

So of course, here you can see I have length width, foundation thickness and so on.

01:59

If I select one of these built in parameters,

02:02

I will not be able to delete it.

02:04

And the reason why I wanted to bring this to

02:06

your attention is that when we create our shared parameters,

02:09

we do not want to conflict with these built in parameters.

02:12

So it's worth understanding

02:14

what the built in parameters are for each category.

02:18

So of course, now we know not to use things like length,

02:20

width and foundation thickness in our shared parameter file.

02:24

Let's go ahead and click, cancel

02:27

and we can now create our shared parameter file

02:31

to do this. We'll go ahead and select the manage ribbon

02:34

and on the managed ribbon,

02:36

we'll select shared parameters

02:40

in our edit, shared parameter dialog box.

02:42

Our first step is to click the create button.

02:45

This will create a new shared parameter file.

02:49

Normally here you would store this on your file server.

02:52

And the reason you do this is then others in

02:55

the team can then access that shared parameter file.

02:58

You could also make the shared parameter file read only

03:01

to stop people editing that and adding additional parameters.

03:06

So for the file name, we'll type in foundations

03:09

and we can go ahead and select save.

03:12

So now that our shared parameter file has been created,

03:14

our first step now is to create a new group.

03:18

The groups help us categorize the parameters neatly.

03:21

For example,

03:22

you can have one shared parameter fold that controls many categories in a project.

03:26

And of course, you could end up with hundreds of parameters all in the same folder.

03:31

So the idea here is by creating a new group,

03:34

it will categorize relevant parameters under the groups you create.

03:38

So for our new group, we'll simply call this one foundations

03:42

and you can now see I have my new group created.

03:45

And of course, if we wanted additional groups,

03:47

we will just go ahead and create them as and when required,

03:51

we'll now begin by creating our new parameters.

03:55

Now,

03:55

here you have to be very careful that you don't make any

03:58

typing errors because you will not be able to edit these afterwards

04:01

as soon as you've created your parameter and click. OK.

04:04

Rev it will then assign a global unique identifier to that parameter.

04:09

And that can then not be changed later on.

04:12

The only option you'd have is to delete it and start again.

04:15

So we've got to be quite careful that we don't make any typing

04:18

errors or problems and errors with the discipline and type of parameter.

04:23

So here I'm gonna type in F

04:26

length.

04:27

OK.

04:28

That's gonna represent foundation length

04:31

and going back to what we said before.

04:33

I know that that's not going to conflict with any built in parameters.

04:37

The discipline is gonna be set to common and the type of parameter is in fact a length.

04:42

So we've double checked that everything looks good and we can click. OK?

04:47

We'll now create another one. So we'll click on you.

04:50

This one is going to be

04:52

F width

04:56

and finally

04:58

another new one in here and this will be F thickness

05:03

and click. OK?

05:05

OK. So our share parameters are now created

05:08

if we go ahead and select, OK?

05:11

We'll now save our family file. So we'll go to the file ribbon

05:15

and we'll select safe.

05:19

And for the farm name,

05:20

let's just simply call this one pad foundation

05:25

notice. Of course, the file type is an RFO. Now that's a

05:28

family file,

05:30

we'll click save.
