Once you activate the visibility widget (), tap any object in the sketch to change its visibility; your changes will take effect when you tap the widget again. (You can still drag and even construct objects normally; the widget responds only to taps.) After you tap the style widget (), you can choose a style from one of the panes that appear and then tap objects in the sketch to change their styles and colors.
Page 1 contains a sample construction of a square; your task is to figure out how it was made. Use the remaining pages to create your own ways of constructing a square, different from the method on page 1. Use object styles, colors, and visibility to distinguish between construction lines and the sides of the finished square. See our earlier blog post to view a short movie demonstrating how the various construction tools work.
As you try out these widgets, I’d love to hear your thoughts about how they work. I tried to make them simple to figure out and easy to use, but they remain a work in progress and I’d love to hear your suggestions for improving them. (Also let us know about other enhancements you’d like to see implemented.)
In creating this format controller, the support of folks at McGraw-Hill Education has been invaluable: WSP developers Matt Litwin, Lyn Headly, and Raymond Cheung; product manager Bryan Corwin; and my long-time colleague and good friend Daniel Scher.
