I am a Cameo newbie but I did get directions from cat_woman on how to cut a solid background of just the shape. Such as wanting to cut a background from a different color to put behind a doily
If you go to the scissor icon at the top of the Silhouette screen you will get a "Cut Style Window" then choose " cut edge" that will only cut the outline of the edge it won't cut the phrase inside of the shape too. The "cut " feature cuts it all .
Hope this helps.
I am not sure how to solve the " ungroup" issue. I ungrouped a file and move all the pieces off the mat that I wanted cut in a different color. Then I put them back one by one to cut them from different color cardstock . I am not sure this is the best way to do it but it works
