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;
