用java生成AutoCAD文件？

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class AutoCADGenerator {
    public static void main(String[] args) {
        ActiveXComponent acad = new ActiveXComponent("AutoCAD.Application");
        Dispatch acadDoc = acad.getProperty("ActiveDocument").toDispatch();
        Dispatch acadModelSpace = Dispatch.get(acadDoc, "ModelSpace").toDispatch();

        // 在模型空间中创建一个直线
        Dispatch line = Dispatch.call(acadModelSpace, "AddLine",
                new Variant(0), new Variant(0), new Variant(0),
                new Variant(100), new Variant(100), new Variant(0)).toDispatch();

        // 保存文件
        Dispatch.call(acadDoc, "SaveAs", "C:\\path\\to\\output.dwg");

        // 关闭AutoCAD应用程序
        Dispatch.call(acad, "Quit");
    }
}
