在ARX中如何加载线型?

shun

在acadiso.lin 中定义有mylinetype, 在层中设定线型,使用AcDb2dPolyline()绘制二维多义线,但线型并没有按照指定的线型绘制线条,是否是在绘制前没有加载线型所致?线型又怎样加载呢? 先用createnewlayer() 并高定当前层,再画线:pNewPline = new AcDb2dPolyline(
AcDb::k2dSimplePoly,parr,0,Adesk::kFalse,0.2*kk,0.2*kk,NULL); 在层中高定线型: void createNewlayer(char *layer,Adesk::UInt16 colorIndex,char* linetype)
{
AcDbLayerTable *pLayerTable;
AcDbObjectId layerId;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pLayerTable,AcDb::kForWrite);
if(!pLayerTable->has(layer)){
AcDbLayerTableRecord *pLayerTableRecord=new AcDbLayerTableRecord;
pLayerTableRecord->setName(layer);
pLayerTableRecord->setIsFrozen(0);//解冻层
pLayerTableRecord->setIsOff(0);//打开层
pLayerTableRecord->setVPDFLT(0);//视区为可见
pLayerTableRecord->setIsLocked(0);//解锁层
/////////////////////////////////
AcCmColor color;
color.setColorIndex(colorIndex);
pLayerTableRecord->setColor(color);
///////////////////////////////////////////
AcDbLinetypeTable *pLineTypeTbl;
AcDbObjectId ltId;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pLineTypeTbl,AcDb::kForRead);
if((pLineTypeTbl->getAt(linetype,ltId))!=Acad::eOk)
{
pLineTypeTbl->getAt("CONTINUOUS",ltId);
}
pLineTypeTbl->close(); pLayerTableRecord->setLinetypeObjectId(ltId);
pLayerTable->add(pLayerTableRecord);
pLayerTable->close();
pLayerTableRecord->close();
}
else{
pLayerTable->close();
}
}
