Using the ExpressDesign Assistant
This message may appear when creating a Express Trace design if the final picture has thick areas of solid color. Some or all parts of the design may not be created. Try using options in the assistant, on the Outline Finder and Expander page and/or the Monochrome Threshold page, to ensure the outlines are not too thick. Cancel the assistant, adjust the picture so that the outlines are easier to isolate with Monochrome Threshold, then open the picture in the ExpressDesign Assistant again.
