I'm trying to use specific fonts in my LaTeX file. But fontspec can't find my desired fonts. I use

family file | grep -i helvetica

to know the names to use in XeTeX using fontspec

/usr/local/share/fonts/HelveticaNeueLTPro-UltLtIt.otf: Helvetica Neue LT Pro,HelveticaNeueLT Pro 25 UltLt
/usr/local/share/fonts/HelveticaNeueLTPro-BdCn.otf: Helvetica Neue LT Pro,HelveticaNeueLT Pro 57 Cn
/usr/local/share/fonts/HelveticaNeueLTPro-Lt.otf: Helvetica Neue LT Pro,HelveticaNeueLT Pro 45 Lt

My .cls part that needs specific fonts is


\setmathfont{Latin Modern Math}

\newfontfamily\bodyfont[]{HelveticaNeueLT Pro 45 Lt}
\newfontfamily\thinfont[]{HelveticaNeueLT Pro 25 UltLt}
\newfontfamily\headingfont[]{HelveticaNeueLT Pro 57 Cn}

\setmainfont[Mapping=tex-text, Color=textcolor]{HelveticaNeueLT Pro 45 Lt}

But fontspec gives errors all the time!

Welcome to TeX.SX! We can't help you unless you tell us specifically what errors you're getting. – ChrisS Aug 19 '13 at 23:37
And perhaps a minimal working example (MWE). Note that, if these lines are indeed the problem, you can copy them into such a minimal file with no issues. – Sean Allred Aug 19 '13 at 23:48
The error is "font-not-found". The font "HelveticaNeueLT Pro 45 Lt" cannot be found. – GSchimiti Aug 19 '13 at 23:53
Did you tried the file name without extension? E.g. HelveticaNeueLTPro-Lt. – Tobi Aug 20 '13 at 0:26
Wow! Works perfect.. Problem solved! Thanks! – GSchimiti Aug 20 '13 at 0:41

You need to use the PostScript name, usually it's the same as the filename sans extension, but not always --- use a font information utility to determine what it is:

\setmainfont[Mapping=tex-text, Color=textcolor]{HelveticaNeueLTStd-Lt}
Main. \bodyfont (bodyfont is same as main)\par
\thinfont Thin.\par
\headingfont Headingfont is condensed.

Maybe interesting: Why should the minimal class be avoided? ;-) – Tobi Aug 20 '13 at 14:20

You can use the file name instead of the font name, e.g. for Helvetica Neue LT Pro-Lt 45 Lt.

\setmainfont[Mapping=tex-text, Color=textcolor]{HelveticaNeueLTPro-Lt}

With Ligatures=TeX instead of Mapping=tex-text, the call is compatible with LuaLaTeX. – egreg Aug 20 '13 at 9:34
