I have two peices of mtext, both use the same style. However, the text are two different types, variations or fonts, not sure what. In properties under TEXT/CONTENTS here are the diferences.
1. starts with "\pxql;"
2. with "{C2;"
I should be abler ot change all m,y text sharing a styole but for some reason I seem to have 1 style with more than one appearance.
BTW, the spell checker for this forum still, is sub par.
The '\pxql;' is for left alignment formatting.
The 'C2' is for colour.
'\f' in the mtext is for font changes
Maybe a screen shot would help.
Check the font used by the text style you want.
Then edit the mtext.
Select all the text within the mtext object.
In the Formatting panel of the ribbon, change the font to the font from your style.
This should remove any internal font changes.
If that doesn't help, select one of the mtext objects, and type the command "list" (without quotes). this will list the contents of the mtext object to the command line. Hit F2 to see the Autocad Text Window, where you can copy and paste the full contents from the Mtext object. Repeat for the other one. Post it here so we can have a look.
