Controlling the size(height) stacked fraction when place in MicroStation Word Processor using true type fonts can be a challenge

Background

The size of the stacked fraction is often larger than rest of text being placed.  When TrueType elements there is a special stacked fraction representation where MicroStation manually draws multiple characters and lines to make something look like a fraction which are measured differently than normal glyphs. This can affect linespacing when placing multi-line text where the linespacing value is not consistent between text lines when text is placed. This issue does not occur when using Bentley fonts as there are designated character for most fractions.

Steps to Accomplish

Set the MS_TEXT_STACKFRACTIONS_SCALE variable

1. Go Workspace>Configuration
2. Define variable MS_TEXT_STACKFRACTIONS_SCALE
3. Set value, start with a value of 40. The value is the percentage scale factor for stacked fractions. (70 is normal for DWG files, and is the default if this configuration variable if not defined.)
4. Close and re-open file
5. Place text, scale factor will now be in affect
