3.2 Braille in Sketchup

Table of Contents

This tutorial is based on the latest free version of Sketchup (Sketchup Make 17.2.2555 64bit).

Preliminary work

To create braille with Sketchup the font Euro-850 must be installed. This can be downloaded here free of charge.

The plugin “round corner” must also be installed. The easiest way to do this is via the extension warehouse directly in Sketchup. The plugin LibFredo6 should also be installed. LibFredo6 is a shared plugin library used by lots of plugins. It enhances plugins with generic capabilities such as default parameters, language translation, checking plugins for updates, trace logging, etc.

It also makes sense to install the plugin “Remove Inner Faces”. With the help of this plugin, inner walls can be deleted with one click. By hand this process takes much longer. Please note: the plugin does not work for all geometries, but is absolutely safe for braille.

Inserting braille

Select the “3D text” tool

insert 3d text (left menĂ¼)

Step 4

Click on the braille with the right mouse button and select “break up into individual parts”.

option can be found in the contextmenu

Each cylinder is now selectable as a separate object.

Text consist of a large number of individual cylinder

Please note: Steps 5 to 8 are not absolutely necessary. Braille in the form of cylinders can also be printed successfully. However, the rounded braille dots look more similar to the braille modules on a braille display. Even though some inexperienced readers preferred the sharp-edged cylinders in the survey, we recommend the rounded version.

Rounding braille

Step 5

Click on another place with the mouse so that cylinders are no longer selected. Then start RoundCorner.

click round corner in the top menu

Step 6

Set the offset value to 0.7 and the segments to 10.

change to options in the round corner menu
Step 7
Click on some of the top surfaces of the cylinders. Depending on the performance of the computer, be careful not to select too many at the same time, otherwise the computer may crash. As a rough guide, 10 points should be adequate.

click on each cylinder

Step 8

To round the cylinders to hemispheres, click on “Generate Geometry”.

click generate geometry

nice hemispheres were generated

Removing the inner walls

Step 9

Between the hemispheres and the outer skin of the actual model there is now a wall that must be removed. This can be done with the plugin Remove Inner Faces with one click. The plugin can be found in the menu item “Extensions”. Please note: no confirmation is given of the removal of the partition wall. To be sure, simply take a look at the model using the “Section plane” tool.
