Students will learn to identify both shape and design by creating vases with the negative impressions of their own
facial profile and develop an understanding of how negative and positive space can be used to create optical illusions.
Example of a student side-profile image.
02
01
Students can work with partners or teams to take sideprofile
photographs of each other’s face; crop the photo
so that it is centered on the student’s face.
Using Adobe Photoshop, or a preferred image editing software, students can import their photograph and remove
the background by duplicating the image layer. Next, go to Select > Subject, then paint the background a dark color
and the foreground (the silhouette) a lighter color. Crop the image so that it is centered on the shape that creates
the silhouette.
The process should look something like this:
TIP:
Need to remove the student’s hair from the silhouette? Using the circle tool, draw a circle that touches both the front
of the forehead and the back of the head. Go to Select > Inverse and delete the hair with the eraser tool.
03
Save the file as a JPG or PNG file and go to vectorizor.io to convert the image to an SVG vector image.
TIP:
Go to page 117 to learn how to convert an image into an SVG image and why this step in the process is needed.
04
Using Fusion 360, OnShape or student’s preferred
advanced CAD program, create a sketch and import
the SVG file. Trim (T) away any line that is not part
of the silhouette. Select the entire silhouette and go
to Modify > Offset > 5mm, then draw Lines (L) to
connect the silhouette and offset line together. This will
create one shape we can further manipulate.
