If I had a pattern that had isolated designs, it would work. Yesterday I did a scan, trace print with engrave and cut around. I had printed the rowmark Christmas vectors on a color laser printer and did several with two colors so I could more easily designate cut, score engrave.
If/when they add some simple drawing tools to the Glowforge workspace, that would be perfect. Like @karaelena pointed out with the Silhouette Pixscan feature.
