Knitting isn't just for wusses anymore

Did you know you can use the Knit tool to create a surface on a face or faces (equivalent to an offset surface at 0.000 distance, commonly called 'offset zero')?  Well you can.

If you are using it create a surface from multiple faces, the faces need to be adjacent, but not overlapping.  You can however offset zero non-adjacent or overlapping faces.  So, if you're planning on forming a solid out of the surfaces later, using the knit tool will tell you upfront if the surfaces are touching and not overlapping (some of the criteria needed to form a solid).
