用Java中的AutoCAD库来读取.dwg文件？ [英] AutoCAD library in Java to read .dwg files?

问题描述

是否有任何开源Java或JavaScript库可用于解析.dwg文件并从中获取对象。

Is there any open-source Java or JavaScript library available to parse .dwg files and get the objects from it.

我想从表中提取数据我的项目的文字。

I would like to extract data from a table of text for my project.

似乎AutoCAD开发人员社区更喜欢.NET和C / C ++而不是JAVA。

It seems that the AutoCAD developer community prefers .NET and C/C++ over JAVA.

我找到的唯一免费替代方法是首先将.dwg转换为.dxf并使用Kabeja lib从中读取。

The only free alternative I found is by converting .dwg to .dxf first and using the Kabeja lib to read from it.

推荐答案

所有已回复的人都有信用，我已经测试了你所有的命题，这是我发现的，截至2015年：

Credits to all who have answered, I've tested all your proposition and here's what I've found , as of 2015:

目前还没有免费且可靠的解决方案来读取和操作.dwg和.dxf文件。这尤其适用于最新版本的AutoCAD，例如：Autocad 2010，Autocad 2013等，RF 2013，RF 2010。

There is currently no free AND reliable solution to read and manipulate .dwg and .dxf files. This applies especially to latest versions of AutoCAD, ex : Autocad 2010, Autocad 2013 etc, RF 2013, RF 2010.

可靠（且价格昂贵）的解决方案将是Teigha by ODA （2000美元一年）和RealDWG在C＃by Autocad（每年5000美元）...

Reliable (and expensive) solutions would be Teigha by ODA (2000$ a year) and RealDWG in C# by Autocad (5000$ a year)...

更便宜的替代品是这样的：

Cheaper alternatives are as such :

• AutoCAD I / O每月10美元（由Augusto Gonclaves建议），但现在功能有限。


• 编写LISPS例程并在AutoCAD 2015/2016的付费实例中使用SCRIPT文件运行它们。


• 等待更完整的实施AutoCad核心控制台..

Kabeja和YCad等开源库可能能够处理较旧的AutoCAD版本，但不要指望这些项目自几年前开始就处于非活动状态。值得关注的是Apache Tika，因为他们开始为.dwg文件编写解析器，但开发速度很慢。

Open-source libraries such as Kabeja and YCad may be able to deal with older AutoCAD versions but do not expect much from them as these projects are inactive since a few years ago. It's worth to keep an eye out for Apache Tika though, since they started writing parsers for .dwg files but development has been slow.

在个人方面，我认为AutoDesk现在在CAD市场上拥有强大而自私的垄断地位，并且他们很难让其他人加入。格式的.dwg文件版本经常变化，我想开源开发人员将不得不在某些时候放弃请改用官方产品。

On a personal note, I think that AutoDesk has a strong and selfish monopoly on the CAD market now and they are making it difficult for others to join in. The format's version of .dwg files changes so often and I guess open-source developers will have to give up at some point and use the official product instead.

让我们希望在未来几年内有更多的开源解决方案

Let's hope for more open-source solutions in the coming years
