I make videos for the Scrappy Dew classroom, however they are not free. But I did make two videos regarding tracing capabilities in SCAL5 to address a really bad video that I knew SCAL users were watching to learn how to trace and it was a disaster in terms of the information it was teaching. So, watch the 2 that I made and it will give you a taste of how the tracing function works. But note there are many more settings that do some amazing things in SCAL5.
