AUTOcad软件API模板大全

以下是一些常见的AutoCAD软件API模板：

1. 命令模板

void myCommand()
{
    // 在这里编写自己的代码
    acutPrintf(_T("Hello World!\n"));
}

void initApp()
{
    acedRegCmds->addCommand(_T("MYGROUP"), _T("MYCOMMAND"), _T("MYCOMMAND"), ACRX_CMD_MODAL, myCommand);
}

void unloadApp()
{
    acedRegCmds->removeGroup(_T("MYGROUP"));
}

extern "C" AcRx::AppRetCode acrxEntryPoint(AcRx::AppMsgCode msg, void* appId)
{
    switch (msg)
    {
    case AcRx::kInitAppMsg:
        acrxDynamicLinker->unlockApplication(appId);
        acrxRegisterAppMDIAware(appId);
        initApp();
        break;

    case AcRx::kUnloadAppMsg:
        unloadApp();
        break;

    default:
        break;
    }

    return AcRx::kRetOK;
}

2. 实体模板

class MyLine : public AcDbLine
{
public:
    ACRX_DECLARE_MEMBERS(MyLine);

    MyLine();
    MyLine(const AcGePoint3d& start, const AcGePoint3d& end);

    virtual Acad::ErrorStatus dwgInFields(AcDbDwgFiler* filer) override;
    virtual Acad::ErrorStatus dwgOutFields(AcDbDwgFiler* filer) const override;
    virtual Acad::ErrorStatus dxfInFields(AcDbDxfFiler* filer) override;
    virtual Acad::ErrorStatus dxfOutFields(AcDbDxfFiler* filer) const override;

    virtual void subList() const override;
};

ACRX_DECLARE_MEMBERS(MyLine);

MyLine::MyLine() : AcDbLine() {}

MyLine::MyLine(const AcGePoint3d& start, const AcGePoint3d& end) : AcDbLine(start, end) {}

Acad::ErrorStatus MyLine::dwgInFields(AcDbDwgFiler* filer)
{
    assertWriteEnabled();

    Acad::ErrorStatus es;
    if ((es = AcDbLine::dwgInFields(filer)) != Acad::eOk) {
        return es;
    }

    return filer->filerStatus();
}

Acad::ErrorStatus MyLine::dwgOutFields(AcDbDwgFiler* filer) const
{
    assertReadEnabled();

    Acad::ErrorStatus es;
    if ((es = AcDbLine::dwgOutFields(filer)) != Acad::eOk) {
        return es;
    }

    return filer->filerStatus();
}

Acad::ErrorStatus MyLine::dxfInFields(AcDbDxfFiler* filer)
{
    assertWriteEnabled();

    Acad::ErrorStatus es;
    if ((es = AcDbLine::dxfInFields(filer)) != Acad::eOk) {
        return es;
    }

    return filer->filerStatus();
}

Acad::ErrorStatus MyLine::dxfOutFields(AcDbDxfFiler* filer) const
{
    assertReadEnabled();

    Acad::ErrorStatus es;
    if ((es = AcDbLine::dxfOutFields(filer)) != Acad::eOk) {
        return es;
    }

    return filer->filerStatus();
}

void MyLine::subList() const
{
    AcDbLine::subList();
}

void initApp()
{
    acrxClassDictionary->add(AcDbLine::desc(), MyLine::desc());
}

void unloadApp()
{
    acrxClassDictionary->remove(AcDbLine::desc());
}

extern "C" AcRx::AppRetCode acrxEntryPoint(AcRx::AppMsgCode msg, void* appId)
{
    switch (msg)
    {
    case AcRx::kInitAppMsg:
        acrxDynamicLinker->unlockApplication(appId);
        acrxRegisterAppMDIAware(appId);
        initApp();
        break;

    case AcRx::kUnloadAppMsg:
        unloadApp();
        break;

    default:
        break;
    }

    return AcRx::kRetOK;
}

这个模板定义了一个自定义的实体类`MyLine`，继承自AutoCAD的`AcDbLine`类，并重载了一些函数，用于存储和读取自定义数据。在初始化函数中，将自定义实体类添加到AutoCAD的类字典中，以便在AutoCAD中创建和编辑这个实体。开发人员可以根据具体需求修改和扩展这个模板。

3. 界面模板

class MyPalette : public AcPane
{
public:
    MyPalette(AcRx::AppInfo* appInfo);
    virtual ~MyPalette();

    virtual void OnCreate();
    virtual void OnDestroy();

private:
    AcDbDatabase* m_pDb;
    CWnd* m_pWnd;
};

MyPalette::MyPalette(AcRx::AppInfo* appInfo) : AcPane(appInfo), m_pDb(nullptr), m_pWnd(nullptr) {}

MyPalette::~MyPalette()
{
    if (m_pDb) {
        delete m_pDb;
    }
}

void MyPalette::OnCreate()
{
    // 创建数据库
    m_pDb = new AcDbDatabase;
    m_pDb->readDwgFile(_T("Template.dwg"));

    // 创建窗口
    m_pWnd = new CWnd;
    m_pWnd->Create(nullptr, _T("My Palette"), WS_CHILD | WS_VISIBLE, CRect(0, 0, 200, 300), this, 0);

    // 添加控件
    m_pWnd->CreateButton(_T("Button 1"), CRect(10, 10, 90, 30), 1);
    m_pWnd->CreateButton(_T("Button 2"), CRect(10, 50, 90, 70), 2);
}

void MyPalette::OnDestroy()
{
    if (m_pWnd) {
        m_pWnd->DestroyWindow();
        delete m_pWnd;
        m_pWnd = nullptr;
    }

    if (m_pDb) {
        m_pDb->closeInput(true);
        delete m_pDb;
        m_pDb = nullptr;
    }
}

void initApp()
{
    // 创建面板
    AcRx::AppInfo* appInfo = acrxGetAppInfo();
    MyPalette* pPalette = new MyPalette(appInfo);
    acedAddObjectToPane(pPalette, AcPane::kFloating);
}

void unloadApp()
{
}

extern "C" AcRx::AppRetCode acrxEntryPoint(AcRx::AppMsgCode msg, void* appId)
{
    switch (msg)
    {
    case AcRx::kInitAppMsg:
        acrxDynamicLinker->unlockApplication(appId);
        acrxRegisterAppMDIAware(appId);
        initApp();
        break;

    case AcRx::kUnloadAppMsg:
        unloadApp();
        break;

    default:
        break;
    }

    return AcRx::kRetOK;
}

这个模板定义了一个自定义的界面类`MyPalette`，继承自AutoCAD的`AcPane`类，并重载了一些函数，用于创建和销毁自定义面板。在初始化函数中，创建自定义面板，并添加到AutoCAD的界面中，以便在AutoCAD中打开和关闭这个面板。开发人员可以根据具体需求修改和扩展这个模板。
