oddbdimension::measurement returning -1 or 0 value
hi,
oddbdimension::measurement() is returning -1 or 0 value.sometimes it calculates correctly but most of the time it returns 0 or -1. i am using version 1.12.i tried with many files.is this a bug?
thanks,
singhn
could you provide an example?

hi,
here are the files.all of them are giving measurement() value 0 or -1.file 116ro is showing some values correct.only correct.dwg is giving all values correct.also could you please tell me how can i extract scaling factor 4 which is being multiplied to actual values in case of correct.zip.
i am extracting measurement value like this for rotated dimension:
double tempmeasurement;
tempmeasurement=protdim->measurement();
thanks,
singhn

values 0 and -1 returned from measurement() is a result of dd bug (it takes place if pre-r15 file is loaded or if r15+ file converted from minor version is loaded).
as a temporary workaround you can call recomputedimblock() in such case.
the value displayed is multiplied by dimlfac value.
both dimstyle and dimension entity have getdimlfac() method (dimension entity may use value from dimstyle or have an override in xdata).
