I am very interested in learning how to carve on acrylic. I am finding it difficult to locate the proper type of acrylic, but in playing around with Designer, I can't find a way to invert text so that I can carve on the back. Is that the proper method? If so, how? I've heard that carves need to be very shallow. I saw a posting o Etsy recently extolling the quality of a 3-D. Is that possible with Designer? Does it require 3-D add on program? Is there a tutorial somewhere explaining this process? I've looked, but I can't find any help. Thanks to anyone willing to share expertise
