前回はOpenSCADで簡単な3Dモデルを作るところまで紹介しました。今回はいよいよ3Dモデリングの最も重要な部分であり、今後より複雑なモデリングをしていくために重要な平面（2次元）の作図と、その図を立体にしていくための押し出し（エクストルージョン）について解説します。

Quite a few RepRap parts were designed in OpenSCAD, and the lightweight interface and open source nature means it’s perfect for designing stuff to print on your Makerbot.

What’s your favorite OpenSCAD command? Perhaps it’s intersection() or difference()? Or are you a polygon() and extrude() modeler? For me, the most useful, and maybe most often overlooke… ...

OpenSCAD is free, open-source software for detailed, programmatically defined, primitive based rendering software. If that sounds complicated, you will be pleasantly surprised at how easy and ...
