When number lines have been created using braille dots (for grades 4 and up, as opposed to a tactile drawing), whichever symbols have been used in their construction should be listed on the Special Symbols page of that braille volume. The intent of the chart on page 6-15 of Guidelines and Standards for Tactile Graphics, is to follow the wording that is shown. You do not have to separate the "Distinctive Coordinate Markers" from the rest of the symbols used--place them all under a cell-5 heading (Number Line Braille Symbols), on the Special Symbols page. Specifics for grade 4 and up are found on pg 6-26 of Guidlines and Standards.

By all means, run it past the classroom teacher! My suggestion would be to show the rectangular prism with its dimensions, followed by the cylinder with its dimensions, and use a transcriber's note to state that the cylinder is shown inside the rectangular prism in print. I think that this approach would be preferable to the side and top view.
Does anyone have any idea how to produce these 3 graphics? I'm going to have to start working on them soon.
It occurred to me, [u]after[/u] I posted my answer in the attachment, that I had [u]not[/u] addressed the following issue from your question:
"The company we are working for recommended a 16 point SimBraille or Braille 2000 font. However, when we used this font size we ended up with 80 characters per line which is problematic."
Some others have reported this "mini" braille occurring when they print to a Tiger embosser. This is caused by something that is incorrect in the settings and the distributor from which you purchsed the embosser should be able to assist with that problem.

Please see attached file which includes information, depending on the method of production, for fonts suitable for tactile graphics.

Wow! That graphic is VERY complicated. Can you please tell me the subject and grade level we are looking at? I am also going to consult further before replying to this post.
BettyI am consulting with another committee members on these complicated graphics. Thanks for your patience!
Please see Unit 2, 2.6 of the Guidelines and Standards for Tactile Graphics and Unit 3, 3.7.2. Often a tactile graphic is on a page by itself which provides a natural separation from the rest of text. I think it may differ from one situation to another, but generally we need every available line on a tactile page for the tactile itself. My own personal opinion is that I don't think that box lines are necessary in most instances.
BettyThe Guidelines and Standards for Tactile Graphics does not specifically mention graduated cylinders. Sometimes you need to take the general principle and apply it to another similar situation. Personally, in this case, I think I would extrapolate from the information given for thermometers. Page 61 of the Guidelines and Standards says, "the numeric indicator should be omitted when depicting measuring tools, ...", and although this is probably referring to the ruler, and protractor, I think it is safe to say that the graduated cylinder is being used as a tool to measure.
Remember, these are [u]guidelines[/u], not rules.
BettyWhile the preferred placement of the values is on the left side of the y-axis, there are occasionally times when the material that is graphed interferes with the placement of the numbers. Since the increment of the values is essential to reading the graph, and since it is not always the same as what is shown on the x-axis, it is preferable to place them to the right than to simply omit them.
BettyA 3-page .pdf file is attached for you to view 3 different possibilities.
1. You could use lead lines and stagger the labels over 2 lines of braille.
2. You could rotate the image so that the labels fit.
3. You could use a key for one or two of the fractions. This should only be used if the key is on the same braille page as the graphic. It is not the best option, as the student would have to refer back to the key.Betty
