ohhh, I guess I need to go back and read through “the book” again. .

Another beautiful job, Kathleen. You may feel taking the time to make these things clear is tedious and unappreciated.

We can’t keep it from being tedious, but it’s massively appreciated.

I have also never seen the notation in a book on grading.
Mine isn’t a book on grading but I show a pattern mapped for grading and how to do it on page 174. See figure 5.74 specifically. I suspect this process is more typical (a holdover maybe) in older companies that preceded computerized grading; those that used the Dario grading machine. I *know* that’s where I’ve seen these instructions, the instruction manual (I use the term loosely, it’s all of four or so pages) for the machine showed this process. I still have copies of the manual but who knows where it is. It’d be interesting to see the instructions for a Sunny Young machine. I wonder if they did something similar.

The point is Esther, if you saw these notations on a pattern, I think you’d know instantly what they were, what they meant and what to do, even never having seen it before.

Very close! Good guess Sarah. The little circle means there’s only the *one* grade rule at that point, not two and that you didn’t forget to write one for the other coordinate. The reason the circle couldn’t indicate “the grade is 1/8th inch in both directions” is that there are four directions -which would it be? Oppositional to the rule as written would equal out to zero .

I have never seen that notation of cross hairs with a circle either, but I am going to say it tells you that the grade is 1/8th inch in both directions so you know that nobody left out the crosswise grade. I have often seen cross hairs with the grade written at the end of each line. This works to tell you whether the grade up is the same as the grade down in both lengthwise and crosswise.

The notation examples you showed are very interesting to me. One I am a CAD grader, almost exclusively, and I never learned that notation. Not in school, not on the job. I have also never seen the notation in a book on grading. I am glad you have explained it!

Since I do children’s grading, I almost always required the designer’s measurement charts. An even better bonus is the POM charts – otherwise I feel compelled to create them. This is so I can see the grading laid out in a nice chart and make sure the grading is even, consistent, and makes sense. Children’s grading is usually all over the map with not much consistency from one designer to the next. I won’t work with designers who won’t supply measurement charts or POM charts.
