Figure 7.27 Create a drawing and save as an SVG file. Credits: Brittany Coe,

Once you've got your drawing saved as an SVG file, import it into Tinkercad.
(You can tweak the Scale and Height before you import the object, but I just import
it as is, and then tweak the size and thickness using the Tinkercad tools.) The ob-
ject will be displayed on the workspace as a flat object like the one seen in Figure
7.28 . Increase or decrease the size of the object as desired.
