Thanks for the ideas. I tried EPS. Silhouette won't read it. I tried .jpg and .png (silly me- no vector to cut), tried .svg: it came into silhouette a strange mess of 4 miniature lines. I decided maybe it was something odd about this particular document. I have lots of these documents with the same basic layers. I tried a second document sled:hen. To my astonishment, saving those cut lines to pdf and importing to Silhouette provided no cutlines to cut at all, a blank page, even though they are clearly visible on the pdf. So then I tried a third document drumcap. I grouped the cut lines, exported as digital high quality pdf, imported into Silhouette, and they cut PERFECTLY. Three different results from documents that are basically the same build. I've attached the first document here, of frogs, and the third document, of drum and cap that did work. Oh, just added the 2nd one, sled:hen. I'm mystified. Also, have to leave shortly for a week, but will be able to read emails but not work with cutting machine until I return. I so appreciate any suggestions.
