如何用ARX实现直线的offset偏移功能？

MIRRO · 发表于 2007-7-19 16:11:00

想实现直线的偏移，然后利用AcDbCurve::getOffsetCurves函数来实现，可是调试的时候，没有出现偏移出来的直线阿？？程序又没有报错，这是怎么回事啊？
哪位高手指点阿！！！
程序如下：（lineId是已经创建好了的直线的ID）
AcDbLine * Pline;
double wide; //偏移量
acdbOpenObject(Pline, lineId, AcDb::kForRead);
AcDbVoidPtrArray offsetCurves;
&nbspline->getOffsetCurves(wide , offsetCurves);
AcDbObjectId ofsID;
enty.AppendEntityToBlockTable((AcDbEntity*)offsetCurves[0], ofsID); //把实体添加到块表记录中
&nbspline->close();

咋没有大侠来回呢？
俺自己换了个方法，改用acedCommand命令了，虽然没啥技术性可言，可只要能实现功能就好～

用acedCommand命令还是遇到问题了。。。
acedCommand(RTSTR, "OFFSET", RTREAL, wide, RTLB , RTENAME , lineName1 , RTPOINT , pt1 , RTLE , RT3DPOINT, OffsetPoint, RTSTR, "", 0);
调试会出错，为什么呢？
请高人指点啊～～

你改成这样试试
acedCommand(RTSTR, _T("OFFSET"), RTREAL, wide, RTLB , RTENAME , lineName1 , RTPOINT , pt1 , RTLE , RT3DPOINT, OffsetPoint, RTSTR, _T(""), 0);

将你的程序作如下修改；将OK
AcDbLine * Pline;
double wide; //偏移量
acdbOpenObject(Pline, lineId, AcDb::kForRead);
AcDbVoidPtrArray offsetCurves;
wide=3;//例如
Pline->getOffsetCurves(wide , offsetCurves);
AcDbObjectId ofsID;
for（int i=0;iclose();

你可以程序中增加这个子函数
Acad::ErrorStatus
addToModelSpace(AcDbObjectId &objId, AcDbEntity* pEntity)
{
AcDbBlockTable *pBlockTable;
AcDbBlockTableRecord *pSpaceRecord;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable, AcDb::kForRead);
pBlockTable->getAt(ACDB_MODEL_SPACE, pSpaceRecord,
AcDb::kForWrite);
pSpaceRecord->appendAcDbEntity(objId, pEntity);
pBlockTable->close();
pEntity->close();
pSpaceRecord->close();
return Acad::eOk;
}
然后用这个函数把你偏移后的对象添加到图纸空间中去
Pline->getOffsetCurves(wide , offsetCurves);
AcDbObjectId ofsID;
addToModelSpace(ofsID, (AcDbEntity*)offsetCurves[0]);
