We have recently created several tutorials that you can follow and become a mass customization expert in no time!
If you follow My First App, My First Drawing and My First Assembly you will know how to create complex applications with dynamic drawings. If you continue with Presets, Test & Debug and User Interface you will learn how to create applications that handle button clicks, mouse clicks and keyboard events.
Documentation and tutorials are living documents and in order to make them as good as possible, we’ve added an edit button at the top right of each documentation page. If you have suggestions on how we can improve, press the button, log in to GitHub and make your change. You will be prompted to create a pull request with your changes, which is just a fancy way of letting us know that you’ve got some improvements.
Good luck on your mass customization path!
