怎样在CAD编程中使用CAD命令?比如Line,ARC等

AcGePoint3d startPt,endPt;

。。。。。初始数据startPt,endPt

AcDbLine *pLine=new AcDbLine(startPt,endPt);
        pLine->setLayer(layer_tc);//添加到指定图层
        AcDbBlockTable *pBlockTable;//获得当前图形数据库符号表
        acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForRead);
        //获得符号表中的模型空间块表记录指针，用于添加对象
        AcDbBlockTableRecord *pblocKTableRecord;
        pBlockTable->getAt(ACDB_MODEL_SPACE,pblocKTableRecord,AcDb::kForWrite);
        pBlockTable->close();
        //将直线添加到模型空间块表记录中
        AcDbObjectId lineId;
        pblocKTableRecord->appendAcDbEntity(lineId,pLine);
    pblocKTableRecord->close();
        pLine->close();


如果直接用cad命令：
acedCommand(RTSTR,"LINE",RTPOINT,pt1,RTPOINT,pt2,RTSTR,"",0);

jiajialin

acedCommand(RTSTR,"LINE",RTPOINT,pt1,RTPOINT,pt2,RTSTR,"",0);

不要乱发哦！我在你上面已经acedCommand了哦！
