Does anyone know how to offset surface both side on Mac? There is no option in the offset tool to choose both sides.
If this question is Grasshopper related (you did not specify a category) You can do two offsets, use a negative value and a positive value, then loft the connection. Or you can use Plug-ins like Pufferfish which have that option on the offset surface. Take your pick.
