+ sign(s) after a radius dimension
+ sign(s) after a radius dimension
(OP)
I have an old drawing that has a table on it. One of the columns in the table is for a radius dimension. To the right of the dimensions in the table there is either one Plus sign (+), two plus signs (++), or three plus signs (+++). Has anyone ever seen this type of tolerancing, if in fact that is what it is?





RE: + sign(s) after a radius dimension
the +, ++, +++ is referring to 3 notes somewhere in the drawing.
RE: + sign(s) after a radius dimension
Quite possible. Also, may be order of preference ("first choice", "second choice", etc.)
But either way, it has to be explained somewhere on the drawing, as it doesn't seem to be part of any drafting standard.
