The Hem PropertyManager and a sample hem

One of the limitations to keep in mind with regard to hems is that SolidWorks cannot fold over a

part so that the faces touch perfectly line on line. Doing this would cause the two sections of the

part to merge into a larger piece, thus removing the coincident faces. SolidWorks, computers, and

mathematics in general do not always handle the number zero very well. In reality, you can often

see light through these hems, and so a perfectly flush hem may not be as accurate as it seems.
