合肥有招聘autocad二次开发的公司吗？有哪位知道，告诉我一声。我现在开发gis,但不是我的兴趣和强项。

王老师，你能不能在网上搞个cad二次开发的培训啊？

hulei_accp 发表于 2005-11-1 23:26:00

发个程序给大家看看,这是我照书做的,在VC++6.0 ,autocad2002下编译通过.

这是画直线的程序cpp:
#include "aced.h" #include "rxregsvc.h" #include "dbents.h" #include "dbapserv.h"
void initApp(); void unloadApp(); void DrawLine();
void initApp() {  acedRegCmds->addCommand("Draw_Line",        "line_hu",        "line_hu",        ACRX_CMD_MODAL,        DrawLine); }
void unloadApp() {  acedRegCmds->removeGroup("Draw_Line"); }
 void DrawLine() {  AcGePoint3d startPt(4.0,2.0,0.0);  AcGePoint3d endPt(10.0,7.0,0.0);  
  AcGeVector3d normal(0.0,0.0,1.0);  AcDbLine *pLine=new AcDbLine(startPt,endPt);  pLine->setColorIndex(3);
 AcDbBlockTable * pBlockTable;  acdbHostApplicationServices()->workingDatabase()      ->getSymbolTable(pBlockTable,AcDb::kForRead);  AcDbBlockTableRecord *pBlockTableRecord;  pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);  pBlockTable->close();  AcDbObjectId lineId;  pBlockTableRecord->appendAcDbEntity(lineId,pLine);  pBlockTableRecord->close();  pLine->close();
}
extern "C" AcRx::AppRetCode acrxEntryPoint(AcRx::AppMsgCode msg, void *pkt) {  switch(msg)  {  case AcRx::kInitAppMsg:   acrxDynamicLinker->unlockApplication(pkt);   initApp();   break;  case AcRx::kUnloadAppMsg:   unloadApp();   break;  default :   break;  }  return AcRx::kRetOK; }
