Create a precast beam profile—Add parameters and create lines

00:03

We're now going to begin by adding some aligned dimensions to our reference points

00:08

to do this on the quick access toolbar, let's select aligned dimension.

00:14

And we're going to begin by selecting the three vertical planes here

00:18

and then making these equal.

00:20

So if we change the width of the beam or the width of the nib,

00:23

we want this to stay centered about the fixed plane.

00:26

So we need to do the same thing for the NIB as well.

00:29

So again,

00:29

here we can select the vertical reference planes that are gonna control that NIB

00:34

and again, make them equal.

00:36

So now that we've added our equal constraints,

00:38

we'll now create the dimensions that are going to control the champers.

00:46

So we'll add these in,

00:47

right? So,

00:54

and some of these,

00:54

I'll add down the bottom just to keep the family a little bit Tidier.

01:01

OK. So there are our dimensions added in,

01:04

we can now select all of those dimensions.

01:06

So here I'm just holding the control key down.

01:08

So I can multiply select all of those half inch dimensions.

01:13

And then on the context ribbon in the label pull down,

01:16

we'll choose Sham.

01:19

OK.

01:20

So we'll now continue to create some more aligned dimensions.

01:24

So again, on the quick access toolbar, we'll select aligned dimension.

01:29

We'll add a dimension here which is going to control the overall width of the beam.

01:34

Another one here which will control the width of the nib

01:38

one here, which will control the depth of the NIP

01:43

must make sure that we get the correct reference planes here as well.

01:45

So we're working on the top reference plane here to this top reference plane

01:50

and then another one to control the overall depth of the beam.

01:55

So now that we've done this, we can now assign our parameters.

01:59

Let's start by selecting this dimension which

02:01

represents the overall width of the beam.

02:03

We'll go up to the context ribbon

02:05

and here we'll go ahead and select width.

02:09

Let's also select this one here.

02:11

This is going to control the overall depth of the beam.

02:15

This one here is the NIP depth

02:20

and finally, here, this one is a NIP width.

02:24

So we now have our parametric framework complete.

02:27

We have our reference plane set up and we have

02:30

all of our labels added to our aligned dimensions.

02:33

So let's now begin by adding in the lines to create our profile to do this.

02:38

We'll select the create ribbon

02:40

and then go ahead and select line.

02:43

So we've got to take care here to make sure that

02:45

we are actually snapping to the correct intersections on our profile.

02:52

So here's our nib so we can come directly up here

02:55

and we'll get the champ at the top

03:00

and again, the champ on the other side of the beam,

03:05

last one on the bottom

03:06

and then we can close up our profile.

03:12

OK. So there's our profile created.

03:14

Now,

03:14

the very first thing we're going to do here is check to make sure that all

03:18

of this line work would in fact update when we change some of the dimensions.

03:23

So we're going to the family types dialogue box

03:27

and we'll start with the width we can see here.

03:29

Currently, we've got 18 inches or 1 ft and six inches.

03:33

So here perhaps we'll change this to 12 inches

03:36

and hit apply

03:37

and I can see that's great. Everything is updated so we can put this back to 18 inches

03:43

and then to apply again,

03:45

let's also check the nib.

03:47

So here, currently, we have a nib depth of six inches, let's set that to eight inches.

03:53

And again, we can see that that's operational

03:55

and perhaps we'll set the overall depth of the beam as well.

03:58

So in here, we could perhaps set um

04:03

and we can see everything's reacted accordingly,

04:05

ok? So I'm going to click cancel here

04:08

and I'll just undo some of those changes here.

04:10

So notice here, we can go and undo all of those family types

04:14

and we're back to our default setting

04:16

and we're back to our default set up

04:20

now before we save the family. What we need to do is just remove these images here.

04:25

The easiest way to do that is to go to the insert ribbon

04:29

and on the insert ribbon, you'll notice here we have manage images

04:34

and on the insert ribbon, you'll note here, we have manage images.

04:39

So I'll begin by selecting this image here.

04:41

And of course, here we can actually then delete that

04:45

and we'll do the same here

04:48

and that's removed those references from the family.

04:51

We can then zoom into the family here.

04:53

And sometimes it's quite nice to actually get

04:55

a better preview than what we're seeing here.

04:58

So we can actually hide the things like the reference planes and the

05:01

dimensions just so we can actually get a preview of our profile family itself

05:06

to do this. We can go to visibility graphics. So we'll select the view ribbon

05:11

and on the view ribbon, we'll select visibility graphics,

05:14

I'll select the annotation categories tab.

05:17

And in this example here, we'll uncheck show annotation categories in this view

05:22

and then click, OK.

05:24

You can see here that we'll end up with a nice clean preview of our profile family.

05:29

So let's go ahead and click save and that will update the fi on disk.
