Hello I have been using the gumball for scaling for years and it always scales in two directions when I pull on the handles.
Nevertheless, sometimes it scales in 1D. I am interested in having it scale 1D all the time. I have referred to this link: http://docs.mcneel.com/rhino/5/help/en-us/commands/gumball.htm
and cannot find a solution.
Any help would be greatly appreciated.
