acedCommand 之使用镜像命令

ads_name ent;
        ads_point pt2, pt3;
        if (acedSSGet(NULL, NULL, NULL, NULL, ent) != RTNORM) {
            return;
        }

        if (acedGetPoint(NULL, L"Pt:", pt2) != RTNORM) {
            return;
        }
        if (acedGetPoint(pt2, L"Pt:", pt3) != RTNORM) {
            return;
        }
        ads_name n1;
        long len = 0;
        acedSSLength(ent, &len);
        for (int i = 0; i < len; i++)
        {
            ads_name a;
            acedSSName(ent, i, a);
            acedSSAdd(a, NULL, n1);
            acedCommandS(RTSTR, _T("MIRROR"),
                RTPICKS, n1,
                RTSTR, _T(""),
                RTPOINT, pt2,
                RTPOINT, pt3,
                RTSTR, _T("N"),
                RTSTR, _T(""),
                RTNONE);
            acedSSFree(n1);
        }
        acedSSFree(ent);

（我这样把集合分成只有一个元素的小集合是为了用getlastEnt得到加入后的镜像实体。）
