Java使用jacob操作autocad，如何添加文字

使用jacob操作Autocad添加文字可以通过以下步骤实现：

1. 获取当前文档的模型空间对象

Dispatch acadDocument = Dispatch.get(activeXComponent, "ActiveDocument").toDispatch();
Dispatch modelSpace = Dispatch.call(acadDocument, "ModelSpace").toDispatch();

2. 创建一个文字对象

Dispatch text = Dispatch.call(modelSpace, "AddText", new Variant("Hello World!"), new Variant(0), new Variant(0), new Variant(0)).toDispatch();

3. 设置文字的位置和样式

Dispatch.put(text, "InsertionPoint", new Variant(new double[] {10, 10, 0}));
Dispatch.put(text, "TextStyleName", "Standard");
Dispatch.put(text, "Height", new Variant(2.5));

4. 添加文字到模型空间

Dispatch.call(modelSpace, "AddEntity", text);

完整的代码如下：

Dispatch acadDocument = Dispatch.get(activeXComponent, "ActiveDocument").toDispatch();
Dispatch modelSpace = Dispatch.call(acadDocument, "ModelSpace").toDispatch();

Dispatch text = Dispatch.call(modelSpace, "AddText", new Variant("Hello World!"), new Variant(0), new Variant(0), new Variant(0)).toDispatch();

Dispatch.put(text, "InsertionPoint", new Variant(new double[] {10, 10, 0}));
Dispatch.put(text, "TextStyleName", "Standard");
Dispatch.put(text, "Height", new Variant(2.5));

Dispatch.call(modelSpace, "AddEntity", text);

注意：在执行该操作之前，需要确保已经成功地连接了Autocad应用程序，并且当前文档已经打开。
