用acdbGetAdsName获得图元名,用acedSSAdd加入到选择集,用acedSSSetFirst亮显并选择static void mydraw采用ddd(void)
{
// Add your code for command mydraw.采用ddd here
ads采用point pt1,pt2;
if( acedGetPoint(NULL,采用T("\nPlease Enter start point: "),pt1) != RTNORM
|| acedGetPoint(pt1,采用T("\nPlease Enter end point: "),pt2)!= RTNORM)
return;
AcGePoint3d p1,p2;
p1 = asPnt3d(pt1);
p2 = asPnt3d(pt2);
//创建一条直线并返回其ID
AcDbObjectId lineId = CreateLine(p1,p2);
//获得其图元名
ads采用name ent;
acdbGetAdsName(ent,lineId);
//加入到一个空的选择集
ads采用name sel;
acedSSAdd(ent,NULL,sel);
//创建一个圆,并得到其ID
AcDbObjectId CircleId = CreateCircle(p1,p2);
//获得其图元名,并加入到先前的选择集
acdbGetAdsName(ent,CircleId);
acedSSAdd(ent,sel,sel);
//亮显
acedSSSetFirst(sel,sel);
return;
