Copy, paste, and paste new

00:02

Copy, paste and paste new.

00:06

In this video, we'll use Copy and Paste, Copy and Paste New and explain the differences between paste and paste new as well as use Press Pull.

00:17

In Fusion 360, we want to carry on with our gear reduction housing assembly.

00:21

If you had any difficulties creating the copies of the hardware, you can also upload the supplied data set, gear reduction housing assembly V5.

00:31

From here we want to continue to use Copy and Paste.

00:35

But what we want to do is we want to make sure that we understand some of the differences between using paste and something called paste new.

00:42

To get started, I'm going to hide the front cover and I also want to hide all of the hardware.

00:48

So I'm going to start by selecting the eye icon on all the hardware.

00:52

Note that you can also do this by selecting all the hardware, right clicking and selecting Show/Hide.

00:59

You also have a show all components and show all bodies option.

01:04

From here what we want to do is we want to begin creating a copy of the smaller idler gear,

01:11

and then we also need to create a copy of it that we can modify.

01:15

So we're going to select the spur gear 10 teeth, we’ll right click and we'll select Copy.

01:20

Then at the bottom of the browser, we're going to right click and select Paste.

01:25

This automatically invokes the move object components,

01:30

and we can move it roughly into place but ultimately we're going to be using Align to position it.

01:36

You'll notice that it's not quite in the right position.

01:39

So I'll go to Modify, Align,

01:42

and then I'll begin by using control or command to select the bottom position of the gear and then I want to select the top position of that hole.

01:51

I want to capture the position and say, OK.

01:53

This will be important later on when we begin to add our joints because we can use as-built joints if everything is in the correct position.

02:02

Now that we've created the identical copy of our idler gear,

02:06

we want to create the version that is the 21 millimeter long idler gear that's going to connect this idler to the drive gear.

02:14

In order to do that, we need to use something called Paste New.

02:19

You can see that here we have spur gear [10 teeth]:1 and spur gear [10 teeth]:2.

02:26

This means that they're both identical copies and any changes I make to one will affect the other.

02:32

This also means that downstream in the bill of materials, parts list, what we're going to see is that we have a quantity of two of that gear.

02:42

If we instead select the gear and we copy it and then if we right click at the bottom of the browser and we select Paste New.

02:51

The Paste New option will create a new, unique version of that component.

02:56

We're going to move it off to the right hand side, we’ll capture its position and we'll say, OK.

03:01

Notice that it's still called spur gear 10 teeth but instead of a colon two after it, it has brackets with a one and a colon one.

03:10

We can select and rename this and instead of 10 teeth, I'm going to put in brackets long.

03:19

So that way we know that this is the long idler gear.

03:23

Now you'll remember that this idler gear is supposed to be 21 mm long.

03:28

If I hide the back housing, it's going to need to travel from the front of this gear all the way to the back of this gear.

03:36

Now let's go ahead and use Inspect and Measure and measure the distance to make sure we understand how far it has to go.

03:44

The distance between these two is 13 mm.

03:48

So we're going to select a tool called Modify Press Pull.

03:52

We're going to select the back face of this gear and we're gonna pull it a distance of 13 mm.

03:59

We're going to say, OK,

03:60

and now we've created a long version of that gear that goes from the front of the other idler gears to the back of the drive gear.

04:08

If we were to do that same operation using Press Pull on one of the other idler gears, notice that it changes both of them.

04:16

Once again, that's because those are two identical gears, we just have to instances or two copies of them inside of this assembly.

04:25

When we use Paste New, what we're doing is we're creating a unique version.

04:30

Now we need to position that.

04:31

So in order to do that, we actually have to use either the front cover or the back housing as there is a position for a shaft to be held in place.

04:41

So we can use Modify and Align again, using control or command we want to select the correct position, capture it and say, OK.

04:51

Now we can hide the front cover and we can show all the gears in our design.

04:57

So we have the larger gear which we've identified as the drive gear and then we have the 16 tooth, which is our driven gear,

05:04

and we have the idler gear train that goes between them.

05:08

Once again, the idlers all being 10 teeth are not going to affect the overall gear ratio.

05:14

As we have 48 tooth in and 16 tooth out that's going to give us our 3:1 reduction or increase,

05:21

depending on whether or not you're talking about torque or rpm.

05:25

At this point, let's bring back some of the housing in this case, we’ll bring back the back housing and the front housing.

05:32

And then we want to save this design before moving on.
