和大家一起分享生成图层和设置线型（类型、颜色、线宽）的简单东东。

上述过程还可以用C语言格式书写.
生成新的图层.
ads_tblobjname("layer","0",ent);
rb=ads_entget(ent);
assoc_dxf_str(rb,1,new_layername);
assoc_dxf_int(rb,0,new_color);
ads_entmod(rb);
ads_relrb(rb);
其中assoc_dxf_int为链表替换程序!

累死了,可不可以这么写?
//添加层
AcDbObjectId CLjDwg::AddLayer(const char* LayerName,
      const Adesk::Int16 LayerColor,
      const char* Linetype,
      AcDbDatabase* pDb)
{
if(pDb==NULL)
  pDb=acdbCurDwg();
//装载线型
pDb->loadLineTypeFile(Linetype,LINETYPE_FILENAME);

AcDbObjectId LineTypeId=AddLineType(pDb,Linetype);
AcDbLayerTable* pLayerTable=NULL;
AcDbLayerTableRecord* pLayerRecord=NULL;
AcDbObjectId LayerId=AcDbObjectId::kNull;
pDb->getLayerTable(pLayerTable,AcDb::kForWrite);
if(!pLayerTable)
  return FALSE;
if(pLayerTable->has(LayerName))
{
  pLayerTable->getAt(LayerName,LayerId);
}
else
{
  pLayerRecord=new AcDbLayerTableRecord;
  AcCmColor color;
  color.setColorIndex(LayerColor);
  pLayerRecord->setColor(color);
  pLayerRecord->setLinetypeObjectId(LineTypeId);
  pLayerRecord->setName(LayerName);
  pLayerTable->add(LayerId,pLayerRecord);
  pLayerRecord->close();
}
pLayerTable->close();
return LayerId;
}
