[原创][arx]生成图层和设置线型（类型、颜色、线宽）
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;
}

太好了，刚好在学这里，真是太感谢了！！
相当谢谢
