Document图形文档对象

Class Name ：AcadDocument

方法

Activate活动

AuditInfo检查图纸完整性

Close关闭文档

CopyObjects复制多个对象（深度克隆）。

EndUndoMark标记操作块的结束

Export导出

GetVariable获取AutoCAD系统变量的当前设置

HandleToObject获取与给定句柄对应的对象

Import导入

LoadShapeFile加载形状文件

This method makes all the shapes in the shape file available to the current drawing. To add a shape into the drawing, use the AddShape method.

New在SDI模式下创建新文档

Dim templateFileName As StringtemplateFileName = "c:\AutoCAD\template\ansi-a.dwt"If AcadApplication.preferences.System.SingleDocumentMode = True ThenThisDrawing.New templateFileNameElseThisDrawing.Application.Documents.Add templateFileNameEnd If

ObjectIDToObject获取与给定对象ID对应的对象

Open打开现有图形文件（DWG）并使其成为活动文档

PostCommand发送命令字符串（异步执行）

PurgeAll从文档中删除未使用的命名引用

Regen重新生成整个图形，并重新计算所有对象的屏幕坐标和视图分辨率

Save保存

SaveAs另存为

SendCommand将命令字符串从VB或VBA应用程序发送到文档进行处理（同步执行）

SetVariable设置cad系统变量

StartUndoMark标记操作`块的开始

WBlock写块

属性 Active活动的（bool）ActiveDimStyle指定激活的标注样式ActiveLayer指定活动图层ActiveLayout活动布局ActiveLinetype指定图形的活动线型ActiveMaterial指定此文档的当前默认材质ActivePViewport指定图形的活动图纸空间视口ActiveSelectionSet获取图形的活动选择集ActiveSpace在图纸空间和模型空间之间切换活动空间ActiveTextStyle指定图形的激活文字样式ActiveUCS指定图形的活动UCSActiveViewport指定图形的活动视口Application程序Blocks获取图形的块集合Database获取对象所属的数据库Dictionaries获取文档的字典集合DimStylesElevationModelSpace指定模型空间中的高设置（z轴）ElevationPaperSpace指定图纸空间中的高设置（z轴）FullName获取应用程序或文档的名称，包括路径Groups获取文档的组集合Height更改对象的高度HWND窗口框架句柄Layers获取文档层集合Layouts获取文档布局集合Limits指定图形限制

限制图形X,Y坐标系。左下和右上

he drawing limits are two-dimensional points in the World Coordinate System (WCS) that represent a lower-left and an upper-right limit. You cannot impose limits on the Z direction.

注意:The lower-left limit controls the LIMMIN system variable. The upper-right limit controls the LIMMAX system variable. The LIMCHECK system variable turns limits checking on and off for the current space.

Linetypes获取文档的线型集合Materials返回数据库的材质集合ModelSpace获取文档的ModelSpace集合MSpace允许从浮动图纸空间视口编辑模型Name指定对象的名字ObjectSnapMode指定对象捕捉模式的设置PaperSpace获取文档的PaperSpace集合Path获取路径PickfirstSelectionSet获取第一个选择集Plot获取文档的打印对象PlotConfigurations获取文档的PlotConfigurations集合Preferences获取首选项对象ReadOnly指定文档或属性是只读还是读写RegisteredApplications获取文档的RegisteredApplications集合Saved指定文档是否有任何未保存的更改(bool)SectionManager返回节管理器对象SelectionSets获取文档的SelectionSets集合SummaryInfo指定图形的特性TextStyles获取文档的TextStyles集合UserCoordinateSystems获取文档的UCS集合Utility获取文档的实用程序对象Viewports获取文档的视口集合Views获取文档的视图集合Width指定对象宽度WindowState指定应用程序或文档窗口的状态

Type: acWindowState enum

acMin: The window is minimized.

acMax: The window is maximized.

acNorm: The window is normal (neither minimized nor maximized).

WindowTitle文档窗口标题

Blocks图形中所有块的集合

Class Name：AcadBlocks

方法

Add创建成员对象并将其添加到相应的集合中

InsertionPoint

Type: Variant (three-element array of doubles)

The 3D WCS coordinates specifying where the Blocks object will be added.

Set blockObj = ThisDrawing.Blocks.Add(insertionPnt, "New_Block")

GetExtensionDictionary获取与对象关联的扩展字典

GetXData获取与对象关联的扩展数据

Item成员队列

SetXData设置与对象关联的扩展数据

属性 Applicationcad应用程序Count成员个数Document对象所属的文档Handle对象句柄HasExtensionDictionary确定对象是否有与其关联的扩展字典ObjectID对象IDObjectName对象的AutoCAD类名OwnerID所有者（父）对象的对象ID
