arx & c++ 常用函数代码

 

1改变实体颜色

Acad::ErrorStatus
changeColor(AcDbObjectId entId, Adesk::UInt16 newColor)
{
    AcDbEntity *pEntity;
    acdbOpenObject(pEntity, entId,
        AcDb::kForWrite);

    pEntity->setColorIndex(newColor);
    pEntity->close();

    return Acad::eOk;
}

2打开model空间
bool OpenWorkingModelSpace()
{
    Acad::ErrorStatus es ;
    AcDbBlockTable *pBlockTbl ;
    AcDbBlockTableRecord *pp ;
    //AcDbObjectId pObjectid;

    // Get the block table
    if ( (es =acdbHostApplicationServices ()->workingDatabase ()->getBlockTable (pBlockTbl, AcDb::kForRead)) != Acad::eOk )
    {
        acutPrintf ("\nCouldn't open the block table!") ;
        return false;
    }
    // Get the Model Space record and open it for read.
    if ( (es =pBlockTbl->getAt (ACDB_MODEL_SPACE, pp, AcDb::kForWrite)) != Acad::eOk )
    {
        acutPrintf ("\nCouldn't get Model Space! Drawing corrupt.\n") ;
        pBlockTbl->close () ;
        return  false;
    }
    pBlockTbl->close ();
    //pp即为model的指针
    //使用pp
    pp->close();
    return true;
}

3创建textstyle

bool CreateTextStyle()
{
    Acad::ErrorStatus es;
    AcDbTextStyleTable * pTextStyleTable;
    es= acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pTextStyleTable, AcDb::kForWrite);
    if (es != Acad::eOk) 
    {
        delete pTextStyleTable;
        return false;
    }
    if(pTextStyleTable->has("textstyle name"))
    {
        //delete pTextStyleRecord;
        pTextStyleTable->close();
        return true;
    }
    AcDbTextStyleTableRecord * pTextStyleRecord = new AcDbTextStyleTableRecord();
    if (pTextStyleRecord == NULL)
        return false;
    

     es = pTextStyleRecord->setName("Mytablestyle");
        //es = pTextStyleRecord->setFont("@宋体",Adesk::kFalse,Adesk::kFalse,936,FIXED_PITCH );
       es = pTextStyleRecord->setBigFontFileName("gbcbig.shx");
       es = pTextStyleRecord->setFileName("txt.shx");
       //es = pTextStyleRecord->setTextSize(2.2);
        //设置属性
    if (es != Acad::eOk) 
    {
        delete pTextStyleRecord;
        return false;
    }
    es = pTextStyleTable->add(pTextStyleRecord);
    if (es != Acad::eOk)
    {
        acutPrintf("not add id");
        delete pTextStyleRecord;
        return false;
    }
    pTextStyleTable->close();
    pTextStyleRecord->close();
   

    return true;
}

4增加blockref到model

bool AddblockrefToModel()
{

    if(pMS == NULL)
      return false;
    AcDbBlockTable *pBlockTable ;
    AcDbObjectId pTitileBlockId;
    // Open the block table for read
    Acad::ErrorStatus es ;
    if ( (es =acdbHostApplicationServices ()->workingDatabase ()->getBlockTable (pBlockTable, AcDb::kForRead)) != Acad::eOk )
        return false ;

    if ( pBlockTable->getAt("xxx",pTitileBlockId) == Adesk::kTrue )
    {    
        return false ;
    }
    pBlockTable->close ();

    
    AcDbBlockReference * pTitileBlockRef = new AcDbBlockReference(AcGePoint3d(xx ,yy,zz),pTitileBlockId);
    AcGeScale3d pscale(scale); 
    pTitileBlockRef->setScaleFactors(pscale);
    //设置属性
    
    pMS->appendAcDbEntity(pTitileBlockRef);
    pTitileBlockRef->close();

    return true;
    
}
5遍历block中的属性 //与遍历block中的实体相似
AcDbObjectIterator *pBlkRefAttItr=pBlkRef->attributeIterator();
for (pBlkRefAttItr->start(); !pBlkRefAttItr->done();pBlkRefAttItr->step())
{
AcDbObjectId attObjId;
attObjId = pBlkRefAttItr->objectId();

AcDbAttribute *pAtt = NULL;
Acad::ErrorStatus es = acdbOpenObject(pAtt, attObjId, AcDb::kForRead);
if (es != Acad::eOk) 
{
acutPrintf("\nFailed to open attribute");
delete pBlkRefAttItr;
continue;
}
if (strcmp(pAtt->tag(),"TITLE:") == 0)
{
CString title = pAtt->textString();
if (strcmp(title,"PROGRESS(D)") == 0)
{ //操作
}
else if (strcmp(title,"PROGRESS(P)") == 0)
{
//操作
}
}
pAtt->close();
}
6公差标注设置函数：
void SetDimtpAndDimtm(double tp,double tm)
{
AcDbDimStyleTable *pDimStyleTbl;
acdbCurDwg()->getDimStyleTable(pDimStyleTbl,AcDb::kForRead);
AcDbDimStyleTableRecord *pDimStyleTblRcd;
pDimStyleTbl->getAt("",pDimStyleTblRcd,AcDb::kForWrite);
if (fabs(tp) == fabs(tm))
{
pDimStyleTblRcd->setDimtfac(1.0)
}
else pDimStyleTblRcd->setDimtfac(0.5);
if (tp == 0.0 && tm == 0.0)
{
pDimStyleTblRcd->setDimtol(0);
}
else
{
pDimStyleTblRcd->setDimtp(tp);
pDimStyleTblRcd->setDimtol(1);
pDimStyleTblRcd->setDimtm(tm);
}
pDimStyleTblRcd->close();
pDimStyleTbl->close();
}

Finding the Active Viewports in Model Space

// Set some viewport information.
AcDbViewportTable* pViewportTable;
if (db.getViewportTable(pViewportTable, AcDb::kForRead)
== Acad::eOk)
{
// Find the first viewport and open it for write.
AcDbViewportTableRecord *pRecord;
if (pViewportTable->getAt(
"*ACTIVE", pRecord,
AcDb::kForWrite) == Acad::eOk)
{
pRecord->setCenterPoint(AcGePoint2d(0.5, 0.5));
pRecord->setHeight(1.0);
pRecord->setWidth(1.0);
pRecord->close();
}
pViewportTable->close();
}
