Stretching Dimensions

[EMD1954]

I create a Dimension Style and it works fine, but when I stretch it, the text does not re-center.  Here's part of my code:

pDimTable->upgradeOpen();

pDimTblRecord = new AcDbDimStyleTableRecord;

pDimTblRecord->setDimscale(96.0);               // dim scale

pDimTblRecord->setDimtxt(0.25);                 // height of text

pDimTblRecord->setDimzin(0);                    // 0'-0"

pDimTblRecord->setDimblk(_T("_CLOSEDFILLED"));  // arrow type

pDimTblRecord->setDimunit(4);                   // architectural

pDimTblRecord->setName(csStyleName);

pDimTblRecord->setDimrnd(0.0);                  // round-off values set to none

pDimTblRecord->setDimtad(1); // sets vertical text position to above the line

pDimTblRecord->setDimtoh(0); // aligns text with the dimension line

pDimTblRecord->setDimjust(0);                   // Positions the text above the dimension line and center-justifies it between the extension lines

pDimTblRecord->setDimtxsty(recId);              // text style record id for "SIMPLEX" - see above

pDimTblRecord->setDimfrac(2);                   // fractions not stacked

What am I missing?

Thanks,

setTextPosition ?

EDIT:....sorry you're talking about dim styles not dims....I'd guess it's almost certainly to do with the text style associated with the dim style....is that centered? AutoCAD itself indicates this could be the DIMTAD, DIMJUST and DIMTXTDIRECTION variables

Yes sorry, it was for dimstyle.  FYI, if I add:

acedCommandS(RTSTR, _T("_DIMTEDIT"), RTSTR, _T("L"), RTSTR, _T("C"), RTSTR, _T(""), RTNONE);

after creating the dimension, it works fine.  Seems there some switch I'm not setting and I tried DDIMTIH, DIMTOFL, DIMSOXD and DIMATFIT.
