My ancestry is Welsh (many generations ago,) so you're right.
'Taffy' is the anglicanized slang spelling of 'Dafydd' (Welsh for David.) 'Goch' is Welsh for 'red' (and, yes, I have red hair.)
Good catch, Bob πSo, the 'perpendicular' thread WAS the one of which you were thinking. I still think it would be a nice feature if the 'circle' cursor could be dragged along an axis, similar to the 'protractor' and 'rotate' cursors. It sure would make drawing a surface perpendicular to a line (axis) a whole lot easier.
