使用Teigha.NET操作DWG基本配置

来源：互联网发布：怎么改软件图标编辑：程序博客网时间：2024/05/18 12:34

一、安装下载需要的环境。

VS2012、Teigha.NET3.03_9的demo

二、新建C# 项目，选择Framework2.0作为目标框架。

添加引用“TD_Mgd_3.03_9.dll"

三、开始写代码，首先初始化Teigha.NET

using (Services svcs = new Services()){}

Teigha.NET的命名空间主要有以下这些：

Teigha.Colors Namespace — Corresponds to OdCm unmanaged classes. Contains classes for working with colors.
Teigha.DatabaseServices Namespace — Corresponds to OdDb unmanaged classes. Contains database classes.
Teigha.Geometry Namespace — Corresponds to OdGe unmanaged classes. Used to carry out general 2D and 3D geometric operations.
Teigha.GraphicsInterface Namespace — Corresponds to OdGi unmanaged classes. Contains classes for entity vectorization.
Teigha.GraphicsSystem Namespace — Corresponds to OdGs unmanaged classes. Contains graphical system classes.
Teigha.Runtime Namespace — Contains system-level functionality classes, such as classes for runtime class registration and identification.

四、Database结构

五、示例：

using Teigha.Runtime;using Teigha.DatabaseServices;using Teigha.Geometry;namespace BatchReplaceText{    class Program    {        static void Main(string[] args)        {            using (Services svcs = new Services()) {                Database db=new Database();                Circle cirl = new Circle();                cirl.Center = new Point3d(100, 100, 0);                cirl.Radius = 14;                BlockTableRecord btr = (BlockTableRecord)db.CurrentSpaceId.Open(OpenMode.ForWrite);                btr.AppendEntity(cirl);                db.SaveAs("C:\\test.dwg", DwgVersion.Current);            }        }    }}
