[arx] sos求助：尺寸标注方面问题！！！！！！！
[arx] sos求助：尺寸标注方面问题！！！！！！！
我是一个arx二次开发cad的新手，做了一个尺寸自动标注的程序，部分代码如下：
acdbdatabase *pcurdb=acdbhostapplicationservices()->workingdatabase();
acdbdimstyletable *pnewdimtable;
pcurdb->getsymboltable(pnewdimtable,acdb::kforwrite);
acdbdimstyletablerecord *pnewdimrecord=new acdbdimstyletablerecord();
pnewdimrecord->setdimasz(20);//设置箭头大小
pnewdimrecord->setdimzin(8);//十进制小数显示时，抑制后续零
pnewdimrecord->setdimexe(30);//设置尺寸界线超出尺寸线距离为400
pnewdimrecord->setdimexo(0);//设置尺寸界线的起点偏移量为300
pnewdimrecord->setdimtxt(30);//设置文字高度
pnewdimrecord->setdimtad(1);//设置文字位置-垂直为上方，水平默认为居中，不用设置
pnewdimrecord->setdimgap(10);//设置文字位置-从尺寸线的偏移量
pnewdimrecord->setdimtih(0);
pnewdimrecord->setdimtix(1);//设置标注文字始终绘制在尺寸界线之间
pnewdimrecord->setdimtofl(1);//即使箭头放置于测量点之外，尺寸线也将绘制在测量点之间
// pnewdimrecord->setdimgap(0.5);
color.setcolorindex(idimcolor);
pnewdimrecord->setdimclrd(color); //尺寸线颜色
pnewdimrecord->setdimclre(color); //尺寸边界线颜色
color.setcolorindex(itextcolor);
pnewdimrecord->setdimclrt(color); //文字颜色
acdbobjectid dimrecordid;
pnewdimtable->add(dimrecordid,pnewdimrecord);
pnewdimtable->close();
pnewdimrecord->close();

acgepoint3d pt1(kd[k].zb_x+t,kd[k].zb_y+t,0);
acgepoint3d pt2(dy.m_chang+t,kd[k].zb_y+t,0);
acgepoint3d pt3(kd[k].zb_x+t,dy.m_kuan+t+150+k*70,0);
acgepoint3d pt6(kd[k].zb_x+t-kd[k].kongjing/2*cos(pi/4.0),kd[k].zb_y+t+kd[k].kongjing/2*sin(pi/4.0),0);
acgepoint3d pt7(kd[k].zb_x+t+kd[k].kongjing/2*cos(pi/4.0),kd[k].zb_y+t-kd[k].kongjing/2*sin(pi/4.0),0);

acdbblocktable *pblocktable;//定义块表指针
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(pblocktable, acdb::kforread);
acdbblocktablerecord *pblocktablerecord;
pblocktable->getat(acdb_model_space, pblocktablerecord,
acdb::kforwrite);
pblocktable->close();
acdbaligneddimension *pdim1 = new acdbaligneddimension(pt1, pt2,pt3,null,dimrecordid);
acdbdiametricdimension *pdim3 = new acdbdiametricdimension(pt6, pt7,leaderlength,dimtext,dimrecordid);
pdim3->setleaderlength(20);
acdbobjectid id;
pblocktablerecord->appendacdbentity(id, pdim1);
pblocktablerecord->appendacdbentity(id, pdim3);
pblocktablerecord->close();
pdim1->close();
pdim3->close();
现在我希望标出的值是图形实际尺寸的一半，而不是尺寸的实际值，不知道对程序怎样操作。恳请高手不吝赐教，再次表示感谢，鲜花赠上
acdbrotateddimension *pdim;pdim->setdimlfac(0.5)就可以了
谢谢wuddy的热心指教，问题解决了。
再次表示感谢！！
