[求助]：怎样画出黑点？

msg888msg

如题，好像AcDbPoint做不到，它只能画出一个点，但我需要的是充当交点的黑点

这个是 pdmode 的系统变量的改成3的吧

可以用AcDbPolyline画一个实心圆

ymd

AcDbObjectId  addent::donut(AcDbBlockTableRecord *pRec,ads_point p1,double r,int co)
{
double d;
d=2*r;
AcDbObjectId id;
AcGePoint3d pc,pc2;
pc.set(p1[X]-d/4,p1[Y],0);
pc2.set(p1[X]+d/4,p1[Y],0);
AcGePoint3dArray aa;
aa.append(pc);
aa.append(pc2);
AcGeDoubleArray a1;
a1.append(1);
a1.append(1);
AcDb2dPolyline *pPL=new AcDb2dPolyline(AcDb::k2dSimplePoly,aa,0,Adesk::kTrue,d/2,d/2,&a1);
  pPL->setColorIndex(co);
if(pRec==NULL){
   AcDbBlockTable *pBlockTable;
   acdbCurDwg()->getBlockTable(pBlockTable,AcDb::kForRead);
   pBlockTable->getAt(ACDB_MODEL_SPACE, pRec,AcDb::kForWrite);
   pBlockTable->close();
   pRec->appendAcDbEntity(id, pPL);
   pRec->close();
   pPL->close();
   }
else{
   pRec->appendAcDbEntity(id, pPL);
   pPL->close();
   }
return id;
}
