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。

AcDbLayerTable *pLayerTable;
acdbCurDwg()->getLayerTable(pLayerTable, AcDb::kForWrite);

AcDbLayerTableRecord *pLayerTableRecord1 = new AcDbLayerTableRecord;

pLayerTableRecord6->setName("F");

AcCmColor color;
color.setColorIndex(1);
pLayerTableRecord1->setColor(color);
pLayerTableRecord1->setLineWeight(AcDb:ineWeight::kLnWt018);//

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;
}
