看了上面的例子，有objectarx的感觉！
createline()
{
acgepoint3d startpt(4.0, 2.0, 0.0);
acgepoint3d endpt(10.0, 7.0, 0.0);
acdbline *pline = new acdbline(startpt, endpt);
acdbblocktable *pblocktable;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(pblocktable, acdb::kforread);
acdbblocktablerecord *pblocktablerecord;
pblocktable->getat(acdb_model_space, pblocktablerecord,
acdb::kforwrite);
pblocktable->close();
acdbobjectid lineid;
pblocktablerecord->appendacdbentity(lineid, pline);
pblocktablerecord->close();
pline->close();
return lineid;
}
用vb。net 开发出来的程序是用dll作扩展名的？
是否只支持cad
是的
请问有相关的参考书卖没有
能不能给一个创建实体的例子,如 创建点线 注写文字等
在此谢谢啦
