GitHubは魔界だ！
今まで必死になってググっても、ChatGPTに質問しても出てこなかった情報がウジャウジャ出てくる。
ただし、ほとんどが外国語。
日本語で書かれた情報は皆無に等しい。
だから翻訳しなければならない。
なぜ日本のIT業界が遅れているのかというと、その理由はGitHubの魔界を探索すれば良く分かるであろう。
罪日バカチョンチャンコロ売国奴産業スパイが特許だの著作権だの企業秘密だのほざいてひた隠しにし、意図的に間違ったことを書籍として出版する。
仕事では新人教育を軽視し、未経験者・転職回数の多い者、中高年を徹底的に拒絶し、排除し、採用しない。
これじゃあ日本のIT業界のレベルがベトナムや北朝鮮といった極貧発展途上国の足元にすら及ばないのも当たり前だ。
以下の情報も本当かどうかはあやしい。
とりあえずCATIAをPythonで自動化する例が出ていたので、本当かどうかは別として、とりあえず転載しておく。
他にはAutoCADのプラグインをC#で作ったりしているのもあった。
GitHubの検索ボックスCATIAやAutoCADなどのキーワードを入れれば出てくる。

Catia を制御するための Python API
CATIA V5を使用して3Dモデルの作成を簡単に自動化するためのAPIです。RICE は、ソリッドとサーフェスを操作するためのいくつかの操作を実装します。
インストール
はじめに
ライブラリのインストール: src フォルダーをダウンロードし、シェル経由でインストールします。
python setup.py
それからインポートして、
from Rice.application import Application
ライブラリのコピー: src フォルダーをダウンロードし、プロジェクトのルート フォルダーにコピーします。 次に、通常のモジュールと同様にインポートします。
