Changing Font of already printed

I have a group of numbers I wish to change from outline to single line. They are in STIX now, I want to change to helvetica.
I can select all of them but other than taking them to Photo Shop or Illustrator I do not see how to change the font for all in LB.
Any ideas?

Marion, are they in the same file? and not converted to shape? If this is the case, you should be able to select all text, possibly individually, and change the font in font options.

It’s hard to find single stroke fonts… Event he ones I have make two passes on each element.

You should be able to select the group of text and use be able to change things via the normal font selection. Much like when you created them.
