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("\n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();

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("\n请输入插入点") , pt) != RTNORM)

acutPrintf(_T("Read Dwg fail"));
return ;
}
AcDbDatabase* pCurDb = acdbHostApplicationServices()->workingDatabase();
AcDbObjectId oid;
es = pCurDb->insert(oid , _T("InsertDwg") , pNewDb ,true);
if (es != ErrorStatus::eOk)
{
assert(FALSE);
return;
}
AcDbBlockReference* pRef = new AcDbBlockReference();
pRef->setBlockTableRecord(oid);

pRef->close();
pRef = NULL;
pBolck->close();
pBolck = NULL;
pBolckRecord->close();
pBolckRecord = NULL;
acDocManager->unlockDocument(pcurDoc);

{
CString strImgPath = _T("C:\\opencv\\samples\\cpp\\tutorial_code\\images\\yellowball.jpg");
AcDbObjectId oid;
//insertIMGFile( oid , _T("0") , strImgPath , _T("yellowball") , AcGePoint2d( 0 , 0 ) , AcGePoint2d( 100 , 100));
InsPic(strImgPath);
return ;
}
static bool InsPic(CString strPath)
{
#if _MSC_VER >= 1600
if (!acrxDynamicLinker->loadModule(_T("acISMobj19.dbx"), true))
{
acutPrintf(_T("无法加载acISMobj19.dbx\n"));
}
#elif _MSC_VER >= 1500
if (!acrxDynamicLinker->loadModule(_T("acISMobj18.dbx"), true))
{
acutPrintf(_T("无法加载acISMobj18.dbx\n"));
}
#elif _MSC_VER >= 1400
//一定要加载此文件，否则加载影像图时会失败
if (!acrxDynamicLinker->loadModule(_T("acISMobj17.dbx"), true))

}
#else
if (!acrxDynamicLinker->loadModule(_T("acISMobj15.dbx"), true))
{
acutPrintf(_T("无法加载acISMobj15.dbx\n"));
}
#endif
AcDbObjectId imgDicId =

{
// Add your code for command ArxProject1._Addxref here
AcDbObjectId oid;
ACHAR lpszBlockName[255];
ACHAR* lpszFileName = _T("C:\\XREGER.dwg");
ErrorStatus es = acedXrefAttach( lpszFileName , lpszBlockName);
