A Path (.wpx) is a drawn Vector graphic path in Trace which is defined by a Start and End point, which may contain other Points, Curves, and Angles.
The Paths are independent of resolution, which means they can be resized without losing detail.
The Path file format in Trace will save all of the Vector elements of the design as you work, whether it is Traced or not.
When the design is completed, save it as a CutArt to load into Designer.
