Dimension values no longer appear on an Archicad 12 project

[Anonymous]

New dimensions appear correctly. Old dimensions have all leaders lines and hash mark as normal, but dimension values have disappeared. They do not reappear even with all layers turned on. Help!

Hi Don,
You should add to your signature your platform and version(s) of archicad and if more than one.

Is this project migrated from a previous version?

Is it just in archicad?
and/or in the layout book?
does it print correctly?

1) Any chance the text pen got set to "white"?
2) Or maybe those dimensions are using a missing font?

Definitely fix your signature to include platform & version.
