The steps in this topic illustrate how to create a second body, starting with a Fusion document containing a single body, and create a second body.

The steps in this topic illustrate how to create a second body, starting with a Fusion document containing a single body, and create a second body. This example uses these Inventor Fusion capabilities:

■ Sketching Sketch on page 135

■ Feature creation Features on page 177

Starting point: a design containing a single body, in the root component This is what the starting point for this example looks like:

Create Multiple BodiesTo learn how to create a design similar to this see: Create a Single Body on page 75

Step 1: Create a sketch and a sketch circle click the Circle command in the Ribbon

Create Multiple BodiesBecause no sketch is currently active, the first step is to create a new sketch. Select a face of the existing body.

Create Multiple BodiesThis creates and activates a new sketch, changes the view to look at the new sketch, and invokes the Circle command. Select a circle center and radius point, away from the existing body. Note that because we selected a face of the existing body, Fusion has generated sketch geometry that coincides with the edges of that face. This sketch geometry is fixed, and so can’t be edited.

Create Multiple BodiesStep 2: Exit the sketch

In this example we illustrate how to exit sketch edit mode. click the Stop Sketch icon in the lower left corner of the screen.

Create Multiple BodiesThis terminates the active sketch, and restores the view to where it was before sketching:

Create Multiple BodiesNote that Fusion recognizes the two closed regions, and shades them in a yellow color.

Step 3: Create a second body using the Revolve feature

Invoke the Revolve command. There are several ways to invoke Revolve. For this simple example, we use the context menu.

Select the circular closed region, using the left mouse button. Click or hold down the right mouse button to bring up the marking menu and the context menu. Choose the Revolve command from the context menu:

Create Multiple BodiesThis brings up the Revolve command, with the circular region as the profile to Revolve.

Revolve requires a second selection – an axis to revolve about. click the Axis glyph:

Create Multiple BodiesThis prompts you to select an axis. You can select sketch lines or linear edges.

In this case we select a sketch line from the face we sketched on:

Create Multiple BodiesOnce the axis is selected, begin dragging. In this example, we will drag in an area that is away from the manipulator. Click and drag the left mouse button in an area of the screen that is not over any graphics. The example drags to the upper right area of the screen. Note that the drag for Revolve,when dragging in open space is a 2-dimensional drag in the plane of the screen.

Create Multiple BodiesNext, change the Operation Type of the Revolve feature to create a new body. Click and hold down the left mouse button over the Operation Type glyph, and choose New Body.

Create Multiple BodiesFinally, click OK in the ribbon to create the Revolve and the new body. The results look like:
