ObjectArx的一次常用方法

1.画一条直线

    static void ArxProject1_DrawLine(void)
    {

        
        //定义两点确定一条直线
        AcGePoint3d ptStart( 0 , 0 , 0);
        AcGePoint3d ptEnd( 100 , 100 , 0);
        AcDbLine* lnNew = new AcDbLine( ptStart , ptEnd);
        
　　　　　//获取当前图形数据库
        AcDbBlockTable* pBlockTable = NULL;
        acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable ,  AcDb::kForWrite);

        AcDbBlockTableRecord* pBlockTableRecord = NULL;
        pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite);
　　　　　
　　　　　//插入当前的图形数据库
        AcDbObjectId lnId;
        pBlockTableRecord->appendAcDbEntity( lnId , lnNew);
　　　　
　　　　　//关闭对象
        lnNew->close();
        pBlockTableRecord->close();
        pBlockTable->close();
    }

2.画一段圆弧

    static void ArxProject1_DrawArc(void)
    {
        //三点创建一个圆弧
        AcGePoint2d ptStartPoint( 0 , 100 );
        AcGePoint2d ptEndPoint( 0 , 100 );
        AcGePoint2d ptCenterPoint(0 , 0);

        AcGeVector2d vecStart(ptStartPoint.x - ptCenterPoint.x ,  ptStartPoint.y - ptCenterPoint.y);
        AcGeVector2d vecEnd(ptEndPoint.x - ptCenterPoint.x ,  ptEndPoint.y - ptCenterPoint.y);
        double StartAng = vecStart.angle();
        double EndAng = vecEnd.angle();
        
        AcGePoint3d pt( 0 , 0, 0);
        AcGeVector3d vec( 0 , 0 ,1);
        AcDbArc* Acr = NULL;
        Acr = new AcDbArc(pt ,vec ,  100, StartAng , EndAng);

        AcDbBlockTable* pBlockTable = NULL;
        ErrorStatus es =  acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite);

        AcDbBlockTableRecord* pBlockTableRecord = NULL;
        es = pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord,  AcDb::kForWrite);
        
        AcDbObjectId oid;
        es = pBlockTableRecord->appendAcDbEntity(oid , Acr);

        Acr->close();
        pBlockTableRecord->close();
        pBlockTable->close();

    }

3.创建一个块，并把它插入到当前的模型空间

    static void ArxProject1_CreateNewBlock(void)
    {
        // Add your code for command ArxProject1._CreateNewBlock here
        ErrorStatus es ;
        
        AcDbBlockTable* pBlockTable = NULL;
        acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite);

        AcDbBlockTableRecord* pBlockTableRecord = new AcDbBlockTableRecord();
        pBlockTableRecord->setName(_T("Hest"));
        
        AcDbObjectId BlockTableOid;
        pBlockTable->add(BlockTableOid , pBlockTableRecord);

        AcDbPolyline* pPloyLine= new AcDbPolyline();
        AcGePoint2d pt1(0 , 0);
        AcGePoint2d pt2(100,200);
        pPloyLine->addVertexAt( 0 , pt1);;
        pPloyLine->addVertexAt( 1 , pt2);
        AcDbObjectId oid;
        pBlockTableRecord->appendAcDbEntity(oid , pPloyLine);

        pPloyLine->close();
        pBlockTableRecord->close();
        pBlockTable->close();
    }

    // - ArxProject1._BlockInsert command (do not rename)
    static void ArxProject1_BlockInsert(void)
    {
        // Add your code for command ArxProject1._BlockInsert here
        AcDbBlockTable* pBlockTable = NULL;
        acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForRead);
        if (!pBlockTable->has(_T("Hest")))
        {
            acutPrintf(_T("不存在块Hest"));
            pBlockTable->close();
            return;
        }

        ads_point pt;
        if (acedGetPoint( NULL , _T("
请输入插入点") , pt) != RTNORM)
        {
            pBlockTable->close();
            return;
        }
        
        AcGePosition3d pt3d = asPnt3d(pt); 
        AcDbObjectId oid;
        pBlockTable->getAt(_T("Hest") , oid );
        AcDbBlockReference* pBlockRef = new AcDbBlockReference( pt3d , oid);

        AcDbBlockTableRecord* pBlockTableRecord = NULL;
        pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite);
        AcDbObjectId refid;
        pBlockTableRecord->appendAcDbEntity(refid , pBlockRef);

        pBlockRef->close();
        pBlockTableRecord->close();
        pBlockTable->close();
    }

4.创建一个新的图层

    static void ArxProject1_CreateNewBlock(void)
    {
        // Add your code for command ArxProject1._CreateNewBlock here
        ErrorStatus es ;
        
        AcDbBlockTable* pBlockTable = NULL;
        acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite);

        AcDbBlockTableRecord* pBlockTableRecord = new AcDbBlockTableRecord();
        pBlockTableRecord->setName(_T("Hest"));
        
        AcDbObjectId BlockTableOid;
        pBlockTable->add(BlockTableOid , pBlockTableRecord);

        AcDbPolyline* pPloyLine= new AcDbPolyline();
        AcGePoint2d pt1(0 , 0);
        AcGePoint2d pt2(100,200);
        pPloyLine->addVertexAt( 0 , pt1);;
        pPloyLine->addVertexAt( 1 , pt2);
        AcDbObjectId oid;
        pBlockTableRecord->appendAcDbEntity(oid , pPloyLine);

        pPloyLine->close();
        pBlockTableRecord->close();
        pBlockTable->close();
    }

    // - ArxProject1._BlockInsert command (do not rename)
    static void ArxProject1_BlockInsert(void)
    {
        // Add your code for command ArxProject1._BlockInsert here
        AcDbBlockTable* pBlockTable = NULL;
        acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForRead);
        if (!pBlockTable->has(_T("Hest")))
        {
            acutPrintf(_T("不存在块Hest"));
            pBlockTable->close();
            return;
        }

        ads_point pt;
        if (acedGetPoint( NULL , _T("
请输入插入点") , pt) != RTNORM)
        {
            pBlockTable->close();
            return;

        AcDbObjectId refid;
        pBlockTableRecord->appendAcDbEntity(refid , pBlockRef);

        pBlockRef->close();
        pBlockTableRecord->close();
        pBlockTable->close();
    }

5.插入一个外部的dwg文件，以块的方式

    static void ArxProject1_InsertDwg(void)
    {
        // Add your code for command ArxProject1._InsertDwgB here
        AcDbDatabase* pNewDb = new AcDbDatabase(Adesk::kFalse);
        AcApDocument* pcurDoc = NULL;
        pcurDoc = curDoc();
        if (pcurDoc == NULL)
        {
            assert(FALSE);
            return;
        }
        acDocManager->lockDocument(pcurDoc);
        Acad::ErrorStatus es;
        es = pNewDb->readDwgFile(_T("D://测试数据//528500-2524250-250-250.dwg")  , _SH_DENYNO , FALSE);
