在另一个DWG文件中复制属性块（包括属性定义）和动态块
要在另一个DWG文件中复制属性块（包括属性定义）和动态块，你首先需要打开目标DWG文件并获取其数据库，然后按照类似的方式进行复制操作。以下是一个简化的示例：#include "dbmain.h"
#include "dbdict.h"
#include "dbblockrec.h"
#include "dbattrib.h"
#include "dbidmap.h"
#include "acdocman.h"
// 在目标DWG文件中复制源块参照及其内容
Acad::ErrorStatus CopyBlockToAnotherDrawing(AcDbBlockReference* pSrcBlkRef, const char* dstDwgFilePath, AcGePoint3d insertionPt)
{
Acad::ErrorStatus es;
// 打开目标DWG文件
AcDbDatabase* pTargetDb = acdbHostApplicationServices()->workingDatabase();
if (dstDwgFilePath)
{
AcApDocumentManager* docMan = acDocManager;
if (docMan)
{
AcApDocument* pTargetDoc = docMan->open(dstDwgFilePath, true, false, false);
if (pTargetDoc)
{
pTargetDb = pTargetDoc->database();
}
else
{
acutPrintf("\nFailed to open target drawing file.");
return Acad::eInvalidInput;
}
}
}
// 获取源块参照关联的块定义
AcDbBlockTableRecord* pSrcBlkRec;
es = acdbOpenObject(pSrcBlkRec, pSrcBlkRef->blockTableRecord(), AcDb::kForRead);
if (es != Acad::eOk)
{
return es;
}
// 将源块定义复制到目标数据库
AcDbBlockTableRecord* pDstBlkRec = pSrcBlkRec->clone(pTargetDb);
if (!pDstBlkRec)
{
pSrcBlkRec->close();
return Acad::eOutOfMemory;
}
pSrcBlkRec->close();
// 创建一个新的块参照
AcDbBlockReference* pDstBlkRef = new AcDbBlockReference();
es = pDstBlkRef->setBlockTableRecord(pDstBlkRec);
if (es != Acad::eOk)
{
delete pDstBlkRef;
pDstBlkRec->erase();
return es;
}
// 设置插入点
pDstBlkRef->setPosition(insertionPt);
// 复制属性（深度复制，包括属性和子对象）
AcDbIdMapping idMap;
es = pSrcBlkRef->copy(idMap, pDstBlkRef, Adesk::kTrue);
if (es != Acad::eOk)
{
delete pDstBlkRef;
pDstBlkRec->erase();
return es;
}
// 对于动态块，还需要更新动态参数
if (pDstBlkRef->isDynamicBlock())
{
AcDbDynamicBlockReference* pDynBlkRef = AcDbDynamicBlockReference::cast(pDstBlkRef);
AcDbBlockChangeIterator* pBCI = new AcDbBlockChangeIterator(pDynBlkRef);
if (pBCI->done() == Adesk::kFalse)
{
do
{
AcDbEntity* pEnt = pBCI->entity();
if (pEnt->isKindOf(AcDbParameterManagerEntity::desc()))
{
AcDbParameterManagerEntity* pParamEnt = AcDbParameterManagerEntity::cast(pEnt);
// 在这里根据需要设置动态参数值，例如：
// pParamEnt->setParameter("MyParamName", newValue);
}
} while (pBCI->next());
}
delete pBCI;
}
// 添加新块参照到目标DWG文件的当前空间
AcDbBlockTableRecord* pCurrentSpace;
AcDbObjectId pCurrentSpaceId;
es = pTargetDb->getActiveSpaceId(pCurrentSpaceId);
if (es == Acad::eOk)
{
es = acdbOpenObject(pCurrentSpace, pCurrentSpaceId, AcDb::kForWrite);
if (es == Acad::eOk)
{
es = pCurrentSpace->appendAcDbEntity(pDstBlkRef);
pDstBlkRef->close(); // 关闭新块参照以便提交到数据库
pCurrentSpace->close();
}
}
return es;
}
// 使用方法
AcDbBlockReference* pSourceBlockRef; // 假设这是你的源块参照
const char* destinationDwgFilePath = "path采用to采用your采用destination采用dwg采用file.dwg";
AcGePoint3d newPosition; // 新的插入点坐标
CopyBlockToAnotherDrawing(pSourceBlockRef, destinationDwgFilePath, newPosition);
