NARRATOR: In this video, we are going

00:03

to create a gate valve using the Make pad command.

00:07

Set the connectors.

00:09

Go over the item settings and set the necessary fields.

00:13

Cover the Options tab.

00:15

Enter the dimensions, and set the icon image.

00:22

The first thing we need to do is choose a pattern.

00:26

Here's a catalog with over 700 patterns

00:29

offered in your Autodesk fabrication software.

00:36

There are some things to consider

00:38

when choosing a pattern.

00:40

What will it be used for, HVAC or pipework?

00:45

What is the shape?

00:47

What dimensions do I need to be able to control?

00:50

What options do I need to consider?

00:53

How many connectors will I need?

00:55

And for HVAC, will it need seems or dampers,

00:60

or will it need some type of handle?

01:03

In our example of building a gate valve

01:06

we will need it for pipework, two round connectors,

01:10

and a handle.

01:12

For the dimensions and options sometimes

01:14

it is best to open the pattern and just start

01:17

playing with it to see if it's going to work out for you.

01:22

I think for our gate valve pattern 868 will work great.

01:29

Another thing to consider is does this pattern

01:33

work in Revit?

01:34

A good rule of thumb is most of the equipment and most

01:38

of the end line patterns do not work in Revit.

01:42

In our database we put all the patterns into a service,

01:46

divided them into their category,

01:48

and marked them if they don't work in Revit.

01:52

This is a very useful way to clearly see the shape

01:55

and be able to test and play with the pattern

01:58

to see if it's going to meet your needs.

02:00

The pattern catalog in this pattern service

02:04

can be downloaded at itembuilders.com.

02:10

I'm going to start by opening the command line console

02:14

by clicking Control Shift C on my keyboard.

02:20

Type make Pat then your pattern no.

02:24

In this case, it'll be 868, and hit Enter.

02:31

When you're done, click OK.

02:35

Then it's going to ask where you want to save

02:38

this item in your database.

02:41

Select the folder, type in the name, and click Save.

02:52

And now close to the console.

02:57

Now we are going to edit the item by right clicking

02:60

on the icon and selecting Edit.

03:05

The flow that has worked for me is

03:08

looking across the tabs I work right from left.

03:13

I'll be covering in later videos what each setting does

03:17

and controls in detail, but for this example

03:20

I just want to cover the basics you will need to know

03:24

for your item to work properly.

03:29

The other tab is where you will say your connectors.

03:34

For this valve you will be using your company's 150 pound

03:38

race face flange connector.

03:52

Just go ahead and lock the other two

03:54

connectors that are not used.

03:59

On the Items tab we will set the specification

04:03

for your company's pipework, the material,

04:16

cut type, and check the board out box.

04:23

Let's also set the service type to valve.

04:31

On the Options tab, we're going to leave

04:34

these as their default settings and just lock each one.

04:39

You can simply just click and drag down

04:41

and it will lock them all.

04:46

Now the Dimensions tab.

04:50

You get these dimensions from the manufacturer's cut sheet

04:54

and also from doing some calculations.

04:57

The key to this is just spending the time putting in the numbers

05:01

to see what each dimension does to the shape of your item.

05:07

The diameter is the valve size, the lengths

05:11

are half the overall length.

05:13

We'll put in the shafts and handle dimension's, body

05:16

widths, and lengths, some more shaft dimensions and that

05:20

should do it.

05:22

After all the dimensions are put in, hit the redraw button

05:28

and there's our gate valve.

05:30

The next thing we want to do is right click

05:33

on the isometric view, save as icon,

05:38

and that'll replace that default.

05:42

Also let's look at the dimensions

05:45

by clicking and dragging down as well.

05:50

And then click OK.

05:54

Now we have our gate valve.
