Hey guys, I have been trying to 3d print braille, hence looking for a way where Rhino could identify the letters and change them its respective braille letter cylinders (Braille ASCII - Wikipedia) with 4mm height. Can someone help? It might need python scripting as well, I am not sure. [Capture]

Here is a little script [image] You have to right click on Id then “Set Multiple Guids”, normally you could select all the objects you want. [image] Then slect in Rhino, click enter if OK. Surface will appears, you can extrude then,… When OK you could bake the geometry in Rhino. braille from textobject.gh (5.4 KB) //Rhino.DocObjects.TextObject obj = (Rhino.DocObjects.TextObject) RhinoDocument.Objects.FindId(guid); var objet = RhinoDocument.Objects.FindId(guid); //Data from wikipedia string ascii = " A1B'K2L@CIF/MSP\"E3H9O6R^DJG>NTQ,*5<-U8V.%[$+X!&;:4\\0Z7(_?W]#Y)="; var charsAscii = ascii.ToCharArray(); string braille = "⠀⠁⠂⠃⠄⠅⠆⠇⠈⠉⠊⠋⠌⠍⠎⠏⠐⠑⠒⠓⠔⠕⠖⠗⠘⠙⠚⠛⠜⠝⠞⠟⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿"; var charsBraille = braille.ToCharArray(); if(objet is Rhino.DocObjects.TextObject) { Rhino.DocObjects.TextObject obj = ( Rhino.DocObjects.TextObject) objet; //get the text of text object string brailleString = obj.DisplayText.ToUpper(); //Conversion to Braille for (int i = 0; i < charsAscii.Length; i++) { brailleString = brailleString.Replace(charsAscii[i], charsBraille[i]); } //To surface if(size == 0) size = 5; Rhino.DocObjects.Font.FontStyle fontStyle = Rhino.DocObjects.Font.FontStyle.Upright; Rhino.DocObjects.Font.FontWeight fontWeight = Rhino.DocObjects.Font.FontWeight.Normal; bool underlined = false; bool strikethrough = false; Rhino.DocObjects.Font font = new Rhino.DocObjects.Font(face, fontWeight, fontStyle, underlined, strikethrough); BoundingBox bb = obj.Geometry.GetBoundingBox(false); Plane plane = new Plane(bb.Min + Vector3d.YAxis * size, Vector3d.XAxis, Vector3d.YAxis); TextEntity text_entity = new TextEntity { Plane = plane, PlainText = brailleString, Justification = TextJustification.BottomRight, Font = font }; Rhino.DocObjects.DimensionStyle dimstyle = new Rhino.DocObjects.DimensionStyle(); dimstyle.TextHeight = size; double smallCapsScale = 1; double spacing = 0; A = text_entity.CreateSurfaces(dimstyle, smallCapsScale, spacing); }

braille.gh (18.6 KB) Hello, this is not too hard with Grasshopper, you have to input a text in uppercase [image] I use this script to output text as Brep [image] Creating Text to colored mesh Grasshopper Hi @laurent_delrieu. Sure, Thanks for the reply. here’s my plan for the script: Inputs: Text as strings (it’s better to be list access) Font Size(text height) color Outputs: Mesh (2d) colored mesh text object Thank you. [image] braille.gh (18.6 KB)

Hey Laurent thanks for the reply! Looks perfect, but here’s my problem- I want it to identify all the text from the drawing itself and replace it with Braille automatically . The image you shared is when you feed text into grasshopper, and it gives you a braille output. I guess I wasn’t clear about it I am sorry.

Hello no problem, but is it text or surface or whatever. If it is text you surely could implement the same logic. Have you some 3dm for example ? I will put my script (corrected) in the above answer. And also put a category to the discussion, Rhino, Rhino developper, grasshopper …

You can consider text in this case, ignoring surfaces. Here’s and example of a file with actual texts, that needs to be converted to Braille- map text.3dm (35.8 KB)

Not a bad idea. But it needs selecting each font and going to properties, changing font style, exploding them to get curves, surfacing them and extruding to get cylinders. A better way?

or just type the words in that font using text object with solid option. also you don’t need to “surface them”. just extrude the curves once you had turn them into braile font, is not a big deal, select all. change the font explode extrude done

Thanks for the suggestion! Infact, text object has an option to provide height as well! It is good when we are making a new file and typing all the text. However, I am looking for something where the texts already exists in the file, and I can convert them directly to Braille :frowning:

Simpler than this?? good luck with it

what if you install a braile font and use it with TextObject?
