The BlenderBIM Add-on supports translations to all languages that Blender supports. We’ll describe how you can help translate the add-on as a translator, or how you can ensure your strings are translatable as a developer. Translations are managed using a separate add-on built for this purpose.

  1. Clone the blenderbim-translations repository. This repository holds all the core translation strings in .po format.

  2. Download the blenderbim-translations add-on and install it as a Blender add-on. This add-on lets you convert translation data to and from the .po files to the BlenderBIM Add-on.

  3. In the Render Properties tab, find the BlenderBIM Translations panel, and browse to where you have closed the blenderbim-translations repository, and click on Setup Translation UI.

You should now see a new interface with two buttons.


How to translate the add-on

Before beginning, look inside the blenderbim-translations repository for a .po file for the language you want to translate to (e.g. de_DE.po for German). If this file does not yet exist, congratulations! You are the first person to translate to this language! Create a folder in blenderbim-translations with your language code and copy the blenderbim.pot language template file to that folder and rename it according to your language (e.g. for German you would copy blenderbim.pot to de_DE/de_DE.po).

Supported language codes are:

'ca_AD', 'en_US', 'es', 'fr_FR', 'ja_JP', 'sk_SK', 'cs_CZ', 'de_DE',
'it_IT', 'ka', 'ko_KR', 'pt_BR', 'pt_PT', 'ru_RU', 'uk_UA', 'vi_VN',
'zh_HANS', 'zh_HANT', 'ab', 'ar_EG', 'bg_BG', 'el_GR', 'eo', 'eu_EU',
'fa_IR', 'fi_FI', 'ha', 'he_IL', 'hi_IN', 'hr_HR', 'hu_HU', 'id_ID',
'ky_KG', 'ne_NP', 'nl_NL', 'pl_PL', 'sr_RS', 'sr_RS@latin', 'sv_SE', 'sw',
'ta', 'th_TH', 'tr_TR'.

As a translator, it is recommended to translate text in bulk by modifying the .po files directly. We recommend installing software such as Poedit. These translation software offer features such as auto translation, suggestions, and tracking. Alternatively, you may edit the .po file as a text file.

Once you have edited the relevant language’s .po file, click on the Update Translations From .po button in the BlenderBIM Translations panel.

How to add new translation strings

When you have new strings to translate, press the Parse BlenderBIM strings to .pot button. This detects strings in the source code using regex patterns and writes out to the blenderbim.pot language template file. You may then diff this file and propagate changes manually to all translated .po files.

The .pot file is only used as a blank template for users to create or compare .po files. The .po files are the source of truth for translation strings. Blender does not read from the .pot or .po files. Instead, Blender reads from blenderbim/ which contains a dictionary of strings formatted specifically for Blender. The file is generated from the .po files. This is generated when we distribute installable packages, or when translators manually press the Update Translations From .po button.


Do not commit the file as it is auto-generated.
