At some point, I started wondering: what <em>is</em> a <code>.c2d</code> file? Could I generate one programmatically? Could I template my projects, parametrically resize joinery, or batch-produce cutting files without clicking through the UI every time?</p> <p>So I did what any reasonable person would do. I cracked one open.</p>
