Adding dimensions

00:02

In this video, will add drawing dimensions.

00:05

After completing this step, you'll be able to use Dimension, create an ordinate dimension, use dimension Break and use dimension right-click options.

00:17

In fusion 360, we're going to carry on with our coupler for production drawing

00:21

but we also want to make sure that we open up our sheet metal handle for production drawing.

00:26

To get started, we want to take a look at using dimensions.

00:30

So under the dimension drop down will notice that there are many different types of dimensions.

00:34

The first option simply called dimension will allow us to create linear, aligned, angular radius and diameter dimensions all with the same tool.

00:43

So let's go ahead and get started by selecting this and let's focus in on the base view of our design.

00:50

We're going to start by adding an angle dimension by selecting the angled lines, drag the view down and we'll place that 36° up above.

01:00

Next, we want to talk about creating a horizontal dimension.

01:05

I'm going to select the center point of this mark in the center point of this mark.

01:10

When I move the cursor around to different positions, it's either vertical, horizontal or aligned.

01:16

Now sometimes that's fine but sometimes you can't get the dimension placed exactly where you want it.

01:21

So in this case I'm going to right click and I'm going to make sure that this is a horizontal dimension,

01:26

and that allows me to place it where I want it.

01:30

I'm going to hit escape to get off the dimension tool.

01:32

I'm going to select this dimension and I'm going to reposition it over here to the right hand side.

01:39

Going to left click to d select that dimension. And let's apply a few more.

01:43

Also note that 'D' on the keyboard is the shortcut key for dimension.

01:48

I'm going to add a radius dimension from this arc and I'm going to add one to this arc as well.

01:55

Notice when I do that where it's positioning the arrow. In this case, it's not positioning it in the correct orientation.

02:02

So I'm going to hit escape and I'm going to try again to make sure that I am selecting the proper thing.

02:07

Notice that as I start to drag out, it begins to point it toward the center.

02:12

Want to make sure that I place it here and I can reposition it later as needed.

02:17

Next, I want to add a vertical dimension.

02:20

I'm going to drag this off into the right hand side. I noticed that I did not use the right click option. I simply placed it where it needed to be.

02:28

I'm also going to add a dimension from the center to the center point of this arc.

02:34

And then, I'm going to zoom out and take a look at all the dimensions that were applied.

02:38

I'm going to go ahead and hit escape on the keyboard and I want to note a few things.

02:43

Any time we have dimensions that overlap, we might want to use what's called a dimension break.

02:49

We're going to select dimension break and select two overlapping dimensions.

02:53

Will select "OK" and notice that it creates a break in the dimension line.

02:58

This helps simplify the dimensioning scheme and make sure that it's very clear which dimensions were looking at.

03:05

Generally you want to do this to any simplified dimensions and always remember that you can reposition these,

03:12

so you don't always need to break the dimension.

03:14

You might find a better location for it.

03:17

In this case, we can't really create a dimension break through the radius value because the arrowhead is actually overlapping that line.

03:25

So I'm going to try to reposition this. So that I get it away from that dimension line and I don't have to use a dimension break.

03:33

Notice that it's pretty cluttered on our drawing view.

03:36

So one way that we could have simplified this is to create a detailed view of this upper portion.

03:42

I can simply add a detailed view and then I can place a larger scaled view in the bottom right hand corner.

03:50

For example of 4-1. And then I could place all my dimensions at this position.

03:55

This is a good way to simplify the drawing view to make it a little bit easier.

04:01

Keep in mind if I do this I'll need to reapply those dimensions.

04:05

So for example, I need to come back and reapply that angle dimension I might need to move my note,

04:11

but I can also come back and I can apply those horizontal and vertical dimensions that I need between these points.

04:18

I can apply my radius value.

04:21

Again, note that as I moved to different positions, the arrowhead is moving as well.

04:26

So we do want to make sure that we capture that design intent.

04:30

Again, I can hit escape on the keyboard and then I can come back and reposition these as needed to a better location that suits it.

04:37

Or I can use my dimension break. Since now my view is a bit larger and the arrowheads are not overlapping.

04:43

So in this case I'll use dimension break between these two and I'll select "OK".

04:48

Now you can see we've got that broken dimension and it's no longer overlapping.

04:53

One thing that this view is missing is the distance to the center from this bottom arc center.

04:59

What we can do is we can leave that dimension in the upper view and we can simply select and delete all the other dimensions that we no longer need,

05:07

because we've recreated them in a different view.

05:10

So this cleans it up a little bit so now we don't have to worry so much about the clutter on that small base view,

05:16

and we can stick to critical dimensions like the distance from the center while focusing the more smaller dimensions on the view itself.

05:24

I'm going to go ahead and move the c note to the bottom right hand corner of that view.

05:29

Let's go back to fit to screen and take a look at what we've done.

05:33

The next thing that I want to talk about is creating an ordinate dimension.

05:37

And to do that, I first want to save this drawing and then move on to my sheet metal handle for production.

05:44

When we originally made this sheet metal handle for production, we use the dimension tool to dimension these positions.

05:51

However, there's another tool that we can use called ordinate dimensions.

05:55

So we need to define the origin which is going to be the starting point and I'm going to drag this down as a zero,

06:01

and then I need to select the positions for each additional point.

06:07

Notice how easy that was to create those ordinate dimensions and it cleans up the drawing view,

06:13

because now we no longer have all these horizontal lines and leaders, we simply know that the position zero is here, 36 millimeter 81.7 and 161.4.

06:24

So this is a much cleaner way to add dimensions for something like a long sheet metal part that has multiple bends.

06:31

Let's go ahead and fit this back to screen and save this drawing view before we move on.
