Change thickness

Next, we’ll alternate the thickness of the

letters to help separate them, and to make our

keyring even better.

The letters are currently all 2 mm thick; we want

the make the ‘C’, ‘D’, and ‘R’ thicker than the ‘O’

and ‘E’, by making them 3mm.

To do this, change the thickness value for the

‘C’, ‘D’, and ‘R’ 3D text blocks to 3, then click

Render. Note that you can drag your model around

to view it from different angles. You can also click

an icon (to the right of the colour) to hide the grid.
