In this section, you will create a hole through the vacuum cleaner body to create a handle. As before, when you built the main body shape, you will overbuild surfaces to create an intersection.
This time, however, you will not use the intersection and trim tools to create a sharp-edged shape. Instead, you will use the Surface Fillet tool to create a rounded edge and trim at the same time.
If you successfully completed Part 3, you can proceed directly to the next step: Creating the handle surface below.
If you were not successful in part 3, open the file called vacuum_part4.wire, located in the wire directory of the CourseWare project. This file contains the completed model from Part 3.
Watch Part 4 of the tutorial.
You will create the handle using a skin surface, built from the handle curve provided in the tutorial file.
First, you will make a copy of the handle curve and move it to the side of the vacuum, to create the two curves needed for the skin.
Click and hold the and move the second curve in the negative y-direction. Move the curve so it is well outside the vacuum body surfaces.
Next, you will create a skin surface between the two handle curves.
You are prompted to select the first curve. Click the first handle curve to select it for the skin surface.
The curve is highlighted, and you are prompted to select the next curve. Click the second handle curve to select it.
The skin surface is created and highlighted in white.
Next, you will use the Surface Fillet tool to trim the handle and upper body surfaces, and to create a rounded edge.
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 lower 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 box 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 outwards from the handle surface. If it is pointing in towards the center of the handle, click the arrow to reverse it.
A small fillet surface is created, and the upper and handle surfaces are trimmed.
To create a comfortable handle, a larger fillet is required.
A Recalc button appears at the bottom right corner of the view.
The fillet is rebuilt to the larger size, providing a more comfortable handle design.
