Using the ExpressDesign Wizard
"Some areas were too thick to be traced."
This message may appear when creating an 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 wizard, on the Outline Finder and Expander page and/or the Monochrome Threshold page, to ensure the outlines are not too thick. Cancel the wizard, adjust the picture so that the outlines are easier to isolate with Monochrome Threshold, then open the picture in the ExpressDesign Wizard again.
