AcDbLine和AcDb2dPolyline怎么转换为AcDbPolyline?


谢谢!

//我所编写的一部分，AcDb2dPolyline转换重要的是BULG //AcDbLine很简单，只是取两端点坐标，从略 if (pobj->isKindOf(AcDb2dPolyline::desc()))
{
AcDb2dPolyline *pLy2d;
AcDbObjectIterator *pVertIter;
pLy2d=AcDb2dPolyline::cast(pobj);
pVertIter=pLy2d->vertexIterator();
AcDb2dVertex *pVertex;
for(vertnum=0;!pVertIter->done();vertnum++,pVertIter->step())
{
vertId=pVertIter->objectId();
acdbOpenObject(pVertex,vertId,AcDb::kForRead);
pt=pVertex->position();
if (vertnum==0)
{
linewidth=pVertex->endWidth();
}
mypt.append(pt);
pVertex->close();
}
pLy2d->upgradeOpen();
pLy2d->erase(Adesk::kTrue);
pLy2d->close();
delete pVertIter;
} for(i=0;i<vertnum;i++)
{
curpt=mypt.at(i);
pkpt.x=curpt.x;
pkpt.y=curpt.y;
bg=0;
if (i>0 && i<vertnum-1)
{
//bgstart bgend--BULG求法从略 }
pPoly->addVertexAt(i,pkpt,bg);
}
if (vertnum>2)
{
pkpt.x=startpt.x;
pkpt.y=startpt.y;
pPoly->addVertexAt(0,pkpt);
pPoly->setBulgeAt(1,bgstart);
}
