The first thing I would look at is the LTSCALE. Make sure you have (in Settings>Drawing Setup) a reasonable horizontal scale set and that the linetype scaler is set to 0.50 (LTSCALE should be half of horizontal scale).
If this is all set correctly, you may want to use the properties dialog to adjust just the ltscale of this text object to see if this helps.
That being said, this is a "user based" forum and not regularly monitored my Carlson Software.
If this doesn't work and you do not receive a better response on this forum, please copy your question along with the version of software you are running and your drawing file and send it to
support@carlsonsw.com so we can assist you further.
Thank you.
