I was told that an Enhancement Request was needed for this occurance, so I submitted one. Be aware of this. If you select the face of a rectangular plate, then use the Measure Tool a set of values will be shown. One of the values is Perimeter. As expected the value is the sum of the outer edges of the selected surface. This is well defined in all Geometry Texts that I know of. Now if you select the outer curved face of a cylinder (not the end) and use the Measure Tool an identical set of data is presented. One of the values is Perimeter. The calculated value is actually 2*PI*diameter. What the heck is this? The definition that Solidworks uses for Perimeter is the sum of the outer bounding edges. The definition that is used in all Geometry Texts is the sum of all outer bounding edges of a two-dimensional shape. My request is that they remove the Perimeter value if this selection is chosen. Is there anyone else that would agree?
