General Info
The Braille Furniture Library allows you to easily add Braille characters to your own models. It has the most commonly used characters and symbols and makes it easy to create new characters.
Every braille character in the library has an invisible background which functions as the braille cell, the space occupied by a single character. This makes resizing and aligning the characters very easy. Braille is a mono spaced font where every character has the same size and the space between the characters of a word is the same.
Alphabet
Characters are lower case by default. There is a special character that prefixes a letter or word to indicate that the following letter or word is upper case: the Capitalize letter prefix to capitalize a single letter and Capitalize word prefix to capitalize a whole word. You place these before the letter or word you want to capitalize.
Numbers & Math symbols
The numbers 0 to 9 are the same as the letters a to j. To indicate that it should be a number you use the Braille number prefix object from the library and place it before the letter.
Examples:
number 1 = Braille numeric prefix + Braille 1.
number 458 = Braille numeric prefix + Braille 4 + Braille 5 + Braille 8.
Punctuation and other characters
There is a separate object Braille space that has no dots. You use it as a space helper for alignment.
Do not use the Braille # pound character to indicate a number.
Sizes & Alignment
The character objects have a size that fits most regulations in the world. These sizes are used as a guide line for the characters:
| Dot Base Diameter | 1.5mm/0.059" to 1.6mm/0.063" |
| Distance between two dots in the same cell | 2.3mm/0.09" to 2.5mm/0.1" |
| Distance between corresponding dots in adjacent cells | 6.1mm/0.241" to 7.6mm/0.3" |
| Dot height | 0.6mm/0.025" to 0.9mm/0.037" |
| Distance between corresponding dots from one cell directly below | 10.0mm/0.395" to 10.2mm/0.4" |
The invisible back of each character is exactly as big as the circumference around the dots. In other words: there's no automatic space between the cells. This is intentional because there is some leeway in the space you can use. This helps by using the space tolerance to fit specific text in a required space. There's one important rule: you must use the same space between all characters in every word of the text.
Character creation
What if you need a character that is not in the library?
A Braille BASE object is included in the library. This object has all dots in a numbered pattern that you can make invisible to create a new character. Dots are numbered in the pattern as shown in the image. Look up the character you need in the documentation listed below and by making one or more dots invisible you can create the character you need.
Braille also uses a long list of contractions. A sort of shorthand for commonly used words. You can find them in the symbols list PDF below.

Didn't find a model that you need? Ask for it in the 
Dodecagon forum thread with a clear description. If the model is interesting for more users and fits in the library I will consider adding it.
