Introduction to Fusion assembly modeling

Create a component from a body, ground new components, and create a new joint.


00:03

As you begin assembly modeling in Fusion, it is important to understand several terms and relationships:

00:10

An assembly is a collection of components that function as a single design.

00:15

A component is a container for design elements like sketches, geometry, bodies, joints, origins, and even other components.

00:26

You can use the position, joint, and motion features to define relationships between components in a design.

00:34

When building models that require assembly, motion animation, or a bill of materials, components are required.

00:42

It is best practice to create components as soon as possible in the design process, before creating geometry.

00:49

Defining the locations of components early in the Timeline keeps the structure of the assembly organized

00:55

and helps to ensure that references update properly.

00:59

As a simple demonstration of assembly modeling, suppose you want to create an assembly using this box design.

01:06

Currently, it does not have any components, but you can create a component from an existing body.

01:13

In fact, you will need more than one component, so that you can create joints between them.

01:19

Making copies of the box first will enable you to create multiple components at once.

01:24

In the Browser, expand Bodies.

01:29

To make a copy of the box, right-click the box body and select Copy.

01:35

Then, right-click the canvas and select Paste.

01:40

Now, use the manipulator arrows to move the copy of the box along the X-axis.

01:47

Click OK to complete the move.

01:50

Right-click and choose Paste again, and then move the box along the X-axis past the second box.

01:57

Click OK.

01:60

In Fusion, you can create components from bodies in several ways.

02:05

To create individual components from a single body, in the Browser, right-click the body and select Create Components from Bodies.

02:14

Click Undo to undo the command.

02:19

To create components from all the bodies, right-click the Bodies folder and select Create Components from Bodies.

02:26

Again, click Undo.

02:29

You can also create new bodies from the Design workspace toolbar.

02:34

On the Solid tab, click the Assemble menu and select New Component.

02:40

In the New Component dialog, verify that From Bodies is selected.

02:45

You can select one or all of the bodies.

02:48

Here, select all three boxes, and then click OK.

02:54

Now, in the Browser, you can see that all three bodies have been converted to components.

03:01

Expand a component to view the body from which it was created.

03:05

With multiple components in the design, you can now create joints.

03:10

A joint positions components relative to one another and defines motion between them.

03:16

From the Assemble menu, select Joint.

03:21

On the component that you want the joint to move, click to place a joint origin.

03:26

Then, do the same on a second component to finish defining the joint position.

03:31

In this case, rotate the model to click the faces between the first and second boxes, starting with the second box.

03:39

Be sure to select the point on the middle of each face.

03:43

In the Joint dialog, on the Position tab, select an Origin Mode for each component:

03:50

Simple, Between Two Faces, or Two Edge Intersection.

03:56

For this example, leave Component 1 and Component 2 set to Simple.

04:02

Next, either click the Motion tab or expand the on-canvas Slider drop-down to select from the available joint types:

04:10

Rigid, Revolute, Slider, Cylindrical, Pin Slot, Planar, or Ball.

04:20

In this case, select Slider, then click OK to confirm.

04:26

To drive the joint and create motion, on the toolbar, click Assemble > Drive Joints.

04:33

This enables you to set a driving value, or the amount the joint will move while being driven.

04:39

Click to select the joint, and then drag the arrow manipulator to set the movement value.

04:46

You can also specify a value.

04:49

When you are finished, click OK.

04:53

This joint currently does not have any limits.

04:56

In the Browser, right-click the new Slider 1 joint and select Edit Motion Limits.

05:03

In the dialog, you can set the Minimum and Maximum distances for the joint to move.

05:09

Select both the Minimum and Maximum checkboxes.

05:13

Leave the Minimum at 0 and set the Maximum distance to 40 mm.

05:19

Click Preview Limits to see the movement, then click again to stop the preview.

05:25

Click OK to confirm the limits.

05:29

The first two boxes are now connected with a joint, while the third does not have any joints and is free moving.

05:36

You can ground the third component to fix it in a set position.

05:41

In the Browser, right-click the component and select Ground To Parent.

05:46

The box component is now grounded,

05:48

and the component icon updates with an anchor.

05:52

The box is now fixed in position and cannot be moved with the pointer.

05:57

You now know how to create a simple assembly by creating several components from bodies,

06:02

connecting components with a joint, and grounding a component to fix it in position.

In Fusion, you can create components from bodies in several ways.

02:05

To create individual components from a single body, in the Browser, right-click the body and select Create Components from Bodies.

02:14

Click Undo to undo the command.

02:19

To create components from all the bodies, right-click the Bodies folder and select Create Components from Bodies.

02:26

Again, click Undo.

02:29

You can also create new bodies from the Design workspace toolbar.

02:34

On the Solid tab, click the Assemble menu and select New Component.

02:40

In the New Component dialog, verify that From Bodies is selected.

02:45

You can select one or all of the bodies.

02:48

Here, select all three boxes, and then click OK.

02:54

Now, in the Browser, you can see that all three bodies have been converted to components.

03:01

Expand a component to view the body from which it was created.

03:05

With multiple components in the design, you can now create joints.

03:10

A joint positions components relative to one another and defines motion between them.

03:16

From the Assemble menu, select Joint.

03:21

On the component that you want the joint to move, click to place a joint origin.

03:26

Then, do the same on a second component to finish defining the joint position.

03:31

In this case, rotate the model to click the faces between the first and second boxes, starting with the second box.

03:39

Be sure to select the point on the middle of each face.

03:43

In the Joint dialog, on the Position tab, select an Origin Mode for each component:

03:50

Simple, Between Two Faces, or Two Edge Intersection.

03:56

For this example, leave Component 1 and Component 2 set to Simple.

04:02

Next, either click the Motion tab or expand the on-canvas Slider drop-down to select from the available joint types:

04:10

Rigid, Revolute, Slider, Cylindrical, Pin Slot, Planar, or Ball.

04:20

In this case, select Slider, then click OK to confirm.

04:26

To drive the joint and create motion, on the toolbar, click Assemble > Drive Joints.

04:33

This enables you to set a driving value, or the amount the joint will move while being driven.

04:39

Click to select the joint, and then drag the arrow manipulator to set the movement value.

04:46

You can also specify a value.

04:49

When you are finished, click OK.

04:53

This joint currently does not have any limits.

04:56

In the Browser, right-click the new Slider 1 joint and select Edit Motion Limits.

05:03

In the dialog, you can set the Minimum and Maximum distances for the joint to move.

05:09

Select both the Minimum and Maximum checkboxes.

05:13

Leave the Minimum at 0 and set the Maximum distance to 40 mm.

05:19

Click Preview Limits to see the movement, then click again to stop the preview.

05:25

Click OK to confirm the limits.

05:29

The first two boxes are now connected with a joint, while the third does not have any joints and is free moving.

05:36

You can ground the third component to fix it in a set position.

05:41

In the Browser, right-click the component and select Ground To Parent.

05:46

The box component is now grounded,

05:48

and the component icon updates with an anchor.

05:52

The box is now fixed in position and cannot be moved with the pointer.

05:57

You now know how to create a simple assembly by creating several components from bodies,

06:02

connecting components with a joint, and grounding a component to fix it in position.
