Creo recognizes PTC internal fonts and TTF fonts. If Catia uses TTF fonts and you know their location then you can copy their files into Creo installation.
in Creo TTF fonts are located in CR3_LOADPOINT\Common Files\Mxxx\text\fonts directory. You can also place additional fonts into some specific directory and use config.pro option PRO_FONT_DIR.
I do not know where fonts are located in CATIA.
