retaining dimension text
hello,
i am exporting a dimension; lets say its a linear dimension; setting its value using setdimensiontext(). but, after opening the exported drawing in acad, when i change something on the dimension, the dimension text changes to the actual length of the underlying line. i want the exported dimension value retained. also, the text position shifts to something different from where it was placed initially. i use settextposition() to set the position.
i am not putting this dimension on a dimension style; but i do use overrides to set certain properties on this dimension.
thanks,
kedar
hello kedar,
could you attach simple drawing with your dimension?
best regards,

sure, here it is.
i got the fix for the change in the dimension value. i was not calling setdimlfac().
also, i forgot to mention in the earlier post that the text size also changes when i do something to the dimension. while you are taking a look in this file, could you please let me know how do i set the tolerance display ? i use
pdimension->setdimtol (hastolerance == variant_true ? 1 : 0); // has tolerance i.e. plusplus, plusminus or minusminus
pdimension->setdimlim (haslimit == variant_true ? 1 : 0); // has limit tolerance
pdimension->setdimtp (toleranceplus); // upper tolerance limit
pdimension->setdimtm (toleranceminus);
thank you,
kedar

hello kedar,
your dimension in attached file has dimtol equal false. so i suppose you have hastolerance equal false in your application. setting other value seems ok.
using settextposition() makes sense with usesettextposition() and with setdimtmove() to 1 or 2. in this case you may control text position completely.
setdimensiontext() - dimention text has string "<>" what is equivalented measurement. i suppose true text is "\a1;4.649\s+0.500^ -0.250;" or "<>\s+0.500^ -0.250;". but in this case using tolerance (dimtol = true) makes no sence.
dwgdirect has extension for recompute dimension block. i recommends use its. your dimension has block which was created no by dwgdirect.
i don't note the change of text size during recompute dimension.
best regards,
