Solid Modeling with the power of Python

Overview

• Packed with simple and interesting examples of python coding for the CAD world.
• Understand FreeCAD's approach to modeling and see how Python puts unprecedented power in the hands of users.
• Dive into FreeCAD and its underlying scripting language.

In Detail

FreeCAD is a general purpose platform for CAD development. It can be extended to use different workbenches to solve different problems. Targeted squarely at the engineering community, FreeCAD is an open source design application built to be extended. Python, the powerful scripting language, is woven deeply into FreeCAD's DNA and gives users unprecedented power to automate and invent.

"FreeCAD [How-to]" is a lean, fast tour of FreeCAD's major workbenches and design philosophy. The reader will get a hands-on introduction to several modeling techniques and learn how Python makes macro automation and design possible.

FreeCAD allows users to design in a variety of ways; from drawing 2D designs as lines and circles to combining primitive solids into complex 3D shapes. Objects can even be created or modified by code you write in Python. FreeCAD even allows power users to extend the application itself with new dialogs, panels, and scripts. This book will not only show you how to get started using FreeCAD in a traditional GUI mode, but will teach you how to harness its powerful scripting language for more power.

What you will learn from this book

• Creating 3D solid objects with python
• 2D draft design and constraint modeling
• Turning 2D drawings into 3D objects
• Combining simple primitives into complex solids
• Recording Macros
• Creating objects with code
• Importing and exporting data
• Creating a Custom python dialog to automate a task
• Harnessing the constraints engine with python

Approach

Written in cookbook style, this book offers many recipes to create objects, import and export data, create 3D solid objects. Each recipe contains step-by-step instructions followed by analysis of what was done in each task and other useful information.

Who this book is written for

If you've been toying around with FreeCAD and want to have more control over your work flow then this book is for you.

The reader needs to have basic knowledge of modeling.

利用Python的力量进行实体建模

概述

充满了简单而有趣的CAD世界中的Python编码实例。

了解FreeCAD的建模方法，看看Python如何将前所未有的力量交到用户手中。

潜心研究FreeCAD及其底层脚本语言。

详细介绍

FreeCAD是一个通用的CAD开发平台。它可以被扩展到使用不同的工作台来解决不同的问题。FreeCAD的目标是工程界，它是一个开放源码的设计应用程序，可以进行扩展。强大的脚本语言Python深深地交织在FreeCAD的DNA中，为用户提供了前所未有的自动化和发明的能力。

"FreeCAD [How-to]"是对FreeCAD的主要工作台和设计理念的一次精简、快速的参观。读者将亲身体验几种建模技术，了解Python如何使宏观自动化和设计成为可能。

FreeCAD允许用户以各种方式进行设计；从以线和圆的方式绘制2D设计到将原始实体组合成复杂的3D形状。对象甚至可以通过你用Python编写的代码来创建或修改。FreeCAD甚至允许强大的用户用新的对话框、面板和脚本来扩展应用程序本身。本书不仅将告诉你如何在传统的GUI模式下开始使用FreeCAD，还将教你如何利用其强大的脚本语言来获得更多的功能。
