I am looking for a font to design Accessibility Media in Brail 2 font. is anyone aware of a source for brail 2 in SketchUp and how this should be installed.
I saw this on the web but wanted some background before jumping in, if someone has experience with this and can provide guidance it would be greatly appreciated!

A way to do it, without extensions, would be to use the Braille font to make a flat and un-extruded 3dtext object and create a component of the hemispherical bump the right size.
Use a circle path and 1/4 circle face and followme…
Move its origin to the bottom center.
Place the bump components onto the 3dfont pattern, snapping to the dots center, and then delete the original 3dtext part.
Group or make a component of the bumps, giving it its name in text.
You can reuse the bump component in any new situation.
If you want another size then use make-unique on a new instance and scale it as desired…
Another option might be to extrude the dots a bit and then use the Round Corner or FredoCorner extension to round the dots. I’m working with the model units set to Meters to avoid issues with tiny faces.
Do you need the actual geometry for the braille? When I was searching for a Braille font I came across one with shadows. If this is just for signage in images of your model maybe you could use that font to create images to insert. That would reduce the geometry count and perhaps make your model easier to manage.
Use will be presentation and documentation for fabrication.
On a relatively small sign, the copy and brail (and ISA) will define the sign size per CBC 11B 703

the long way to say no faking it.
OK. So if you need to model the actual geometry for the sign in SketchUp, I would suggest you use the “Dave Method” to avoid the tiny face issue. Or model the sign in meters (so a dot would be modeled at 1.5 to 1.6 meters in diameter and then scale them down afterward.
