Regarding your very excellent tutorial#11 on Cylindrical
is Fig 8 a misprint, regarding offsetting the knitted surface
bi-directionally, where the option to do so is not offered? I can
see that your illustration (page 6) shows offsetting only one
direction as well. This option is not offered when offset is
selected from the Surfaces Toolbar, where it is offered from the
Sketch Toolbar. Am I missing something here?
