Erin Yes, sometimes the zoom limitation is frustrating. Stacho or Martin B would have to comment on your question. Can you adjust the resolution/size of the images you are tracing? I have had some luck with this using scanned paper, xvi and pockettopo imports. It took me some experimentation to get it right. Also I avoid images with kilometers of cave and stick to 100's of meters in one image.
