Customization

You have a nice looking custom keycap, but to make it truly custom and ✩ polished ✩, you have to add some flair to it! This can range from adding some fillets and text to the top, to adding completely new models to the keycap or changing the entire shape of it!

For example, our current keycap has a pretty sharp edge on the top, which may look ugly to some people. To fix this, we can add a fillet or chamfer by simply clicking on the edge or face and using the Fillet/Chamfer tools, as seen below.

Although this is nice, the keycap is still pretty bland... What's the use of a custom keycap if there's no text, art, or anything special?

...So let's do that!

To add text, create a new sketch on the top of the keycap and use the Text tool under the Create menu to add text to the sketch, making sure it fits onto the keycap! Once you have that, select the blue text and Extrude it!
Direction doesn't matter, but be aware of the keycap's thickness if you cut into the top like I did below. Go too deep into the keycap, and suddenly you're cutting into the stem and ruining the model!

Additionally, you can go a step further and draw on the keycap! By using the Canvas tool, you can make a reference image to trace over, such as in the example of the eyes on my keycaps for the biblically accurate keyboard!

To add a canvas, go to Insert and click on the photograph icon named Canvas. After that, you can trace over it with any tool in the Sketch menu.
The most common tool to trace with is with the Fit Point Spline tool, which automatically curves a line depending on the points specified. Other tools like lines, polygons, and circles can also be used, but typically depends on the design you're aiming for.

but THAT'S STILL BORING!! What if you want a custom shape like the keycaps on my Engipad?
