a matter of some clarification, just for my own personal gratification.
the word radius, believe it or not, is the cause of serious confusion in my line of work. not on my part, mind you, but in the people i talk to.
today, i spoke to a gentleman who said he "wanted to radii the corners of his part." now this, this is emblematic of more than one problem with my telephone friends' favorite goofy little word. let's address the problems one by one. first, radii is not a singular term. ever (neither is axes, children.). number two. radius is not a fucking verb. you cannot radius something, try as you might. third, radiused is not a word. it's neither an adjective nor a past tense verb. consequently, you shouldn't say that "an edge is radiused," because that makes no fucking sense. and finally, believe it or not, i've heard it used as an adverb, pretty much. as in, "the tool moves radiused down to point five..." it could be worse--they could've said 'radiusly'. but it's still wrong. wrong wrong wrong.
to sum up, not everything that is round or circular can be described with some derivation of the word radius. that's why we have other words like round, circle, diameter, curve, arc, bend, et cetera.
thank you for your time.
