If your older PathTrace design layers were traced from the inside to the outside of the design, the entire design may not display properly on the Editor. This is because the FrameShop Editor displays the top layer of the CutArt, which when traced from the inside-out, is the inner-most mat.

However, when you bring the design to the Cutting Preview, the entire design will display and cut properly.

It is not necessary to retrace the design, but if desired, you can bring these designs back into Trace and retrace them from the outside-in (outside-most layer toward the inner-most layer), so that all of the layers will display on the Editor.
