Thank you for your patience Christina! We're still researching the issue. (You're correct. Troubleshooting support for CorelDRAW on the Mac is pretty thin out there!)
Hi MenWithAMessage!
Before we offer advice, we'd like to see the graphic you're working on, and which prompted this set of questions. Would you please reply with that graphic attached?
Christina, we have done some researching to identify problems similar to what you are describing.
Depending on the version of CorelDRAW, the Macintosh OS, and the age of your computer's hardware, the following may help you.
- In the menus, open "Tools > Options" and then select the "Global" options in the dialog box that appears. (Note: Depending on your version of CorelDRAW, the menus and dialog box options may be slightly different.)
- Uncheck the option "Enable Background Tasks."
- Restart your computer and try the same operations in CorelDRAW.
Changing this setting can help because CorelDRAW makes high demands on your computer, and this setting attempts to allow other operations to occur in the background on your computer. If available hardware is older, or hard-drive space, or RAM memory is low, your computer will appear to lock-up when trying to keep everything running and also opening templates, saving files, or other operations.
Please report back to let us know if this helps for you. Please also reply with your version of CorelDRAW and Macintosh OS.
Finally, please also review the following video to check if you have installed CorelDRAW fully on your Macintosh.
Hi Christina!
I think we can all relate to your experience here. In order to provide accurate information for you we would like to know more about your setup and the template you're trying to open.
- What version of CorelDRAW are you using?
- What version of the Macintosh OS are you using?
- Is it possible that you could upload a copy of one of the templates that produces the crash in your CorelDRAW?
Hope to hear from you soon!
Hi Christina!
Corel maintains the following website for learning CorelDraw: https://learn.corel.com/
On that website I searched for "installing templates" and this help video was made available: https://learn.corel.com/tutorials/how-to-use-coreldraw-templates/#1552316717834-7a23715d-20ca
There are tabs at the top of the webpage for PC, Macintosh, and several other selections.
Please let us know if this provides the information you require!
Thanks for the question!
Our experts want to note first that this is an example where we "follow print." Attached is a quick example of how you could handle this by putting the long horizontal graph across two facing pages, with the Y-coordinate scales arranged exactly as shown in print.
We would like to note that we have attached a "new and improved" graphic <line-graph-sample_Across-facing-pages_MK-Rev2.docx>. The newly attached graphic still uses colors to indicate the actual plotted graph lines. You should use distinct tactile line types for each (more on that below).
Other than that, the image reflects accurate placement of braille around the different parts of the graph.
You probably also know the following, but we are including it to be complete for other readers. All of these are found in GSTG 6.6.2.2. GSTG is "Guidelines and Standards for Tactile Graphics" and is found at the following URL on BANA's website http://www.brailleauthority.org/tg/index.html
- Grid lines should be the least distinct lines on the graph
- X and Y axis lines should be tactually distinct from and stronger than the grid lines
- Tick marks may be the same line strength as the X and Y axis lines, and should cross the axes by 1/4" (6mm) on each side
- The plotted lines should be the boldest and most distinct in the entire graphic.
- Plotted lines should be solid unless shown as broken lines in print. This is to retain any relationship between line type and the mathematical significance of the line type that was incorporated by the original designers of the print graphic.
- Each plotted line must be tactually distinct so it can be easily followed by readers. Variations could involve width or height of the lines. This is especially important when plotted lines cross as is shown in your original print example.
We hope this answers your question! Please let us know if you have any follow-ups.

. Reason: Include accounting for technical errors in the plotted lines and the right end of the X-coordinate scale. (See two bullets in the middle of the text part of this posting.)

Taylor,
The BANA guidelines for tactile graphics are currently in the final approval phase. We don't have special knowledge of their contents. BANA, NBA, and other organizations will actively announce those revised guidelines when they are available.
In the meantime, we can share the following:
The NBA training materials for TGs include the following examples as appropriate for the mat plan method. (Note that these examples from NBA training materials use pre-UEB braille.)
The attached figure 1 shows print graphics that would be rendered as mat plan tactiles.
The attached figure 2 displays how one would use the mat plan in a tactile image of the graphic shown.
The attached figure 3 shows a block figure that should be produced as a tactile using the layering method. The layering method is used in this case because there is empty space under cubes in the top layer.
The attached figure 4 shows how the layering method would be used to produce a tactile graphic of the block object shown in figure 3. Notice how shading is used to signify the blocks, and no shading is used to signify where there are no blocks in each layer.
We hope this answers all of your questions for now!
The maths symbols in the graph should be included on the SPECIAL SYMBOLS PAGE.
From what is provided in this thread, and considering the level of maths involved, we would expect the students to be familiar with those symbols. However, a decision on whether or not to include a standard TN prior to this graph with the special maths symbols could be made at the agency-level and/or in consultation with curriculum specialists.
Hi Laurie,
With this particular TG we're actually trying to accomplish two things.
First, we want to stay within the guidelines. Ensuring that our work is consistent with the guidelines means that students and instructors alike will have materials that easily fit into their lessons, lesson planning, and testing processes.
Second, we have to make sure the TGs do not introduced unusual conditions on students or instructors, when learning and teaching the concepts. As indicated in our previous response, because of the way sine waves are normally displayed (that is, horizontally) and the way the the question is asked, the student and instructor will expect to have values plotted above and below the horizontal X-axis rather than to the left and right of a vertically-oriented X-axis.
In this case, we recommend omitting every other label and/or stair-stepping the labels for the x-axis. This is consistent with the 4th bullet in GSTG 6.1.5.10
You're asking a very good question (again)!
We on the TG Skills Group are comparing notes on your question and we will get back with you as soon as we can.
Hi Laurie!
You were on the right track!
According to GSTG 6.5.1.10 allowable to omit alternate labels while keeping the coordinate marker (6.5.1.10, 4th bullet). This can help by compressing the length of the line. However, after reviewing the print diagram to be rendered as a TG it isn't clear what values will have to be plotted on the graph. With this in mind, depending on the need to plot values from the referenced unit circle, it may be preferable to retain all of the labels.
If it is impossible to fit the graph any other way, you can change the horizontal format to a vertical format in order to accommodate a long line without the need for runovers (6th bullet). There are other formatting requirements as indicated below.
Here is the full text of GSTG 6.1.5.10 (print page 6-21). I have bolded the 4th and 6th bullets to make them easier to identify. Please note that the bulleted items are listed in a hierarachy, with the most preferable option at the top of the list.
Our experts note that even though GSTG 6.1.5.10 allows for a rotation of the graph, the problem being asked of the student is to graph an f(x) vs x relationship. This could be confusing if the graph were actually rotated.
__________________________________________________________________________
6.5.1.10 Hierarchy for accommodating a long number line without runovers should consider:
-
<li style="list-style-type: none;">
- starting the number line at the margin. If accompanied by an exercise number, the exercise number can be left on one line, and the number line can be moved down to a new line. A blank line is inserted between the exercise number and the number line.
- shortening the length of the line segments between integers.
- omitting unused portions of the line.
- omitting alternate labels while keeping the coordinate marker.
- moving a long label away from the number line by placing it below the line reserved for ordinary labels and connecting it to its coordinate marker with a lead line.
- changing the horizontal form to vertical. Rotating a number line will produce a vertical line that may be thought of as comparable to the y-axis of a Cartesian graph; therefore, the number line should be transcribed with the smallest number at the bottom of the page and increasing upward. The tick marks should straddle the axis line, 1/4 inch (6 millimeters) on either side of the axis line. Dots 25 of the value are aligned with the tick mark.

The "mat plan" and "layering method" described in GSTG 6.15 and 6.16 are used to help learners work up to the concept of volume by counting blocks inscribed on a flat surface. Once students understand that they can slice an object into layers and determine area by counting those blocks, they have made a step toward understanding volume.
And -- jumping many years ahead -- the same idea of slicing an object into pieces, determining the approximate area of each slice, and then adding all those slices together, will come in handy when students encounter integral calculus!
I think we're homing in on some important details!
Section 6.15 of GSTG focuses on orthographic drawings (the common multi-part drawing including separate front, side, and top views of an object), rather than pictorial drawings. Here is an example of a pictorial/3D drawing and an orthographic drawing of the same object: https://civilseek.com/wp-content/uploads/2018/12/orthographic-projection-drawing.jpg
The advice provided in our earlier responses is based on our determination that the instruction and exercises in pages you provided for us, focus on teaching and helping learners to use the concept of depth. As implied in GSTG 2.10, if the concept of depth is necessary, then a 3D view is desirable.
Are we closer now to answering all of your design questions? 🙂
Taylor,
We want to be cautious and indicate that our response was specific to the examples we reviewed. Since we do not have the entire textbook, we can only advise on the specific graphics in question. Each instance should be reviewed and formatted according the context. Consistency throughout a transcription should always be a priority because that allows the readers to focus more on the content than the way the content is expressed.
GSTG 3.3 discusses the use of a planning sheet and recommends documenting the planning process. Listing the content, texture, symbols and labels helps track pertinent information and provide consistency in graphics presented throughout the transcription. As far as going back through the whole book, that would be up to the transcriber and tactile artist.
Drawing from the substantial experience with TGs and transcription on this Skills Group committee, we can elaborate on this to say that when it comes to tactile graphics, 3D shapes have always been one of the most challenging types of figures to render.
There have been many different innovations for rendering different kinds of images in tactile forms.
Among these innovations, a few stand out:
- Using a texture to identify a particular side in isometric and oblique drawing of 3D shapes. This first started being used about 15-20 years ago, and was typically used to identify the top, not front, of an object.
- Use of engraving lines for edges that are going inward or receding in a figure, and use the embossed lines for edges that are going outward or "coming out of" the page.
However, these are only attempts to use tactile features to communicate the shape of an object. None has proven to be universally helpful for all tactile readers. That said, we could expect that a reader who has been taught to understand these methods would benefit when receiving materials using the same tactile techniques consistently in the future. However, the opinions and feedback of proofreaders may not always provide the best benefit for all (and especially new) tactile readers.
Our best service to tactile readers is to consistently apply guidelines as shown in GSTG and related references. That way, we can be assured to provide content in a form that will likely be encountered in the future, even if materials are produced by someone else.
