Help! Clueless on global defaults
 

Hi, folks, I'm new to Graffle, but very excited about learning it.

One thing I can't figure out is how to revise a document's global settings with regard to font, top/bottom margins for text in shapes, etc.

Does anyone know how to do this? Thanks.

Option-click a drawing tool to inspect it, the appropriate inspectors will show and you can make your changes there. After that, those settings will hold.

Fonts are determined by inspecting the Text Tool, pretty much everything else is set on the Shape Tool.
