In this section, you will create the on/off button for the vacuum cleaner.
You will create the button detail in two stages. First, you will create a recess in the body surface where the button will sit. Then, you will create the button so it sits flush with the body surface.
Because one set of surfaces will fit into another, you will use layers to organize the geometry.
Opening the tutorial file (optional)
If you successfully completed Part 5, you can proceed directly to the next step, Creating a cylinder for the power button.

If you were not successful in part 5, open the file called vacuum_part6.wire, located in the wire directory of the CourseWare project. This file contains the completed model from Part 5.

Watch Part 6 of the tutorial.
Creating a cylinder for the power button
First, you will create a cylinder surface for the outline of the power button.

Creating two surfaces for the button and the recess
The cylinder you have just created will be used twice. First, you will use it as the sidewall of the power button, then a second copy will be used to create the sidewall of the recess in the main body.
The upper surface will also be used twice. A copy will be used to create the top of the power button. Most of the surface will be trimmed away, but the part that is left will be flush with the vacuum body.
The original upper surface will be trimmed to create the recess for the button.
To avoid confusion with these copied surfaces, you will first create layers for the body surfaces, and for the power button surfaces.

Now, you will create a second layer for the power button.
Choose Layers > New to create a layer.

You now have two copies of the cylinder and top surface, one on the body layer, and one on the power_button layer.

Next, you will use the copied surfaces to create the power button. You will use the Surface fillet tool to trim and round the edge of the power button.

Only the two surfaces you copied are visible.

. Double-click the icon to
open the option box.
Change the settings to Construction Type RADIUS and Radius 0.25.

Close the Surface Fillet option window.
You are prompted to select the first set of surfaces.

The surface is selected and highlighted in pink, and an Accept button appears in the bottom right corner of the view.

You are then prompted to select the second set of surfaces.

The surface is selected and highlighted in yellow, and an Accept button appears in the bottom right corner of the view.
Arrows appear on both surfaces, indicating on which side of the surfaces the fillet will be built.

The pink arrow needs to point in towards the inside of the vacuum surfaces. If it is pointing out from the surfaces, click the arrow to reverse it.
The yellow arrow needs to point inwards on the cylinder surface. If it is pointing outwards, click the arrow to reverse it.
The fillet surface is created, and the upper and cylinder surfaces are trimmed to create the power button.

Creating the power button hole
Next, you will use the Surface Fillet tool to trim and round the edge of the power button recess.

are used for this fillet surface, and so you don’t need to open

You are prompted to select the first set of surfaces.

The surface is selected and highlighted in pink, and an Accept button appears in the bottom right corner of the view.

The pink arrow needs to point in towards the inside of the vacuum surfaces. If it is pointing out from the surfaces, click the arrow to reverse it.
For the recess, the fillet needs to be created on the other side of the cylinder, so the yellow arrow needs to point outwards on the cylinder surface. If it is pointing inwards, click the arrow to reverse it.
The fillet surface is created, and the upper and cylinder surfaces are trimmed to create a recess for the power button.
