OpenSCAD Mac版(CAD繪圖軟件)

OpenSCAD for mac是一款非常好用的CAD繪圖軟件，軟件功能強(qiáng)大，操作簡單。這是一款可用于創(chuàng)建立體三維CAD對(duì)象的軟件，它是用程序的方式生成模型，搞軟件的人應(yīng)該很熟悉這種方式，但習(xí)慣交互式造型設(shè)計(jì)的就不用看這個(gè)了。創(chuàng)建模型的方法就像是用腳本語言編寫一段程序，然后編譯，總體感覺簡單、便捷、易學(xué)，教程完善，安裝方便，功能強(qiáng)悍。這是一款非常專業(yè)的三維建模軟件。歡迎來9553免費(fèi)的下載體驗(yàn)。

軟件說明

OpenSCAD是一個(gè)用于創(chuàng)建立體三維CAD對(duì)象的軟件。它是免費(fèi)軟件,可用于GNU /Linux，MSWindows和蘋果OSX。不同于大多數(shù)自由軟件，用于創(chuàng)建3D模型(如著名的應(yīng)用Blender)，OpenSCAD不專注于藝術(shù)方面的3D建模，而是專注于CAD方面。因此，它可能當(dāng)你正在尋找一個(gè)建造3D機(jī)械零件的應(yīng)用，但可能不是你在期望的你非常感興趣的在電腦動(dòng)畫電影。

OpenSCAD不是一個(gè)交互建模工具。相反，它是在腳本文件中描述對(duì)象，并呈現(xiàn)從腳本文件中的3D模型，上面寫著像一個(gè)三維的解釋。這給了你(設(shè)計(jì)師)的建模過程的完全控制權(quán)，使您可以輕松地更改任何步驟在建模過程中，甚至設(shè)計(jì)所定義的配置參數(shù)。

OpenSCAD包括兩個(gè)主要的建模技術(shù)：首先，建設(shè)性的立體幾何(CSG),第二、二維輪廓映射。

AutoCAD DXF (qcad, librecad )文件作為數(shù)據(jù)交換格式的二維輪廓。除了2D路徑輸出，但也可以從DXF文件讀取設(shè)計(jì)參數(shù)。除了讀取DXF文件，OpenSCAD還可以讀取和創(chuàng)建三維模型的STL和OFF文件格式。此類openCASCADE,區(qū)別是:openCASCADE是一個(gè)標(biāo)準(zhǔn)的C++庫，本身就是專業(yè)的CAD庫;而openSCAD是利用openCSG和CGAL,這兩個(gè)標(biāo)準(zhǔn)C++庫來完成CAD, 主要以立體幾何圖像技術(shù)和openGL渲染完成CAD模型。

OpenSCAD基于圖形的構(gòu)建立體幾何用openGL做渲染的軟件庫,使用C++語言編寫并在windows/Linux系統(tǒng)中支持大多數(shù)硬件。

CGAL開源項(xiàng)目,目標(biāo)是以C++庫的形式提供方便，高效，可靠的幾何運(yùn)算，CGAL應(yīng)用到在諸多方面有幾何運(yùn)算需要的地方，如：計(jì)算機(jī)圖形學(xué)，科學(xué)可視化，計(jì)算機(jī)輔助設(shè)計(jì)與建模，地理信息系統(tǒng)，分子生物學(xué)，醫(yī)學(xué)成像，機(jī)器人技術(shù)和運(yùn)動(dòng)規(guī)劃，網(wǎng)格生成，數(shù)值計(jì)算方法等等.

官方介紹

OpenSCAD is a minimalist Mac OS X application that provides access to a powerful scripting language that allows you to create and preview 3D CAD models. The application simply reads the source code and then renders the 3D object.

As a result, your 3D models will be based on parameters that can be changed in no time. What’s more, OpenSCAD can read design parameters included in DXF, STL, and OFF files.

Use the OpenSCAD scripting language to generate precise 3D models

The OpenSCAD user interface is represented by a single window where you can easily input the source code, compile the data, and preview the results. All in all, the app’s design is fairly intuitive, so the key is to actually learn how to use the scripting language efficiently.

On the OpenSCAD project page you can access the extensive app documentation that includes both usage instructions, and commented examples.

To get you started, the developers offer a “cheat sheet” that include most common commands for creating 2D or 3D objects, for running transformations or Boolean operations, for accessing mathematical functions, and so on.

Of course, the same area includes an user manual for the OpenSCAD language that provides details about supported values and data types, variables, conditional and iterator functions, mathematical operators and functions, trigonometric or string functions, transformations, or modifier characters.
