<p>好好学习下C++， 括号放错位置了：</p><p>&nbsp;&nbsp;&nbsp; for(int j=0;j&lt;3;j++)<br/>&nbsp;&nbsp;&nbsp; {&nbsp; <br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acutPolar(pt, rads, 100*j, startpt);<br/>&nbsp;&nbsp; acutPolar(startpt,rads+3.1415926/2,50,endpt);&nbsp;<br/>&nbsp;&nbsp; AcDbLine*pLine=new AcDbLine(AcGePoint3d(startpt,startpt,0),<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; AcGePoint3d(endpt,endpt,0));<br/>&nbsp;&nbsp;<font color="#ff0000">//&nbsp; }错误地方</font><br/>&nbsp;&nbsp;&nbsp;&nbsp;pLine-&gt;setColorIndex(1);//红色 <br/>&nbsp;&nbsp;&nbsp;&nbsp; AcDbBlockTable *pBlockTable;<br/>&nbsp;&nbsp;&nbsp;&nbsp; acdbHostApplicationServices()-&gt;workingDatabase()-&gt;getSymbolTable(pBlockTable,AcDb::kForRead);<br/>&nbsp;&nbsp;&nbsp;&nbsp; AcDbBlockTableRecord *pBlockTableRecord;<br/>&nbsp;&nbsp;&nbsp;&nbsp; pBlockTable-&gt;getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);<br/>&nbsp;&nbsp;&nbsp;&nbsp; pBlockTable-&gt;close();<br/>&nbsp;&nbsp;&nbsp;&nbsp; AcDbObjectId lineId;<br/>&nbsp;&nbsp;&nbsp;&nbsp; pBlockTableRecord-&gt;appendAcDbEntity(lineId,pLine);<br/>&nbsp;&nbsp;&nbsp;&nbsp; pBlockTableRecord-&gt;close();<br/>&nbsp;&nbsp;&nbsp;&nbsp; pLine-&gt;close(); </p><p>&nbsp;&nbsp;<font color="#ff0000">&nbsp; }//正确地方</font></p>
