Hello, In a document I'm writing I'm using urw-garamond font successfully. However I also use metaUML library for metapost where I'd like to have helvetica (or nimbus, heros, etc.). For latin modern sans, I can use this: string metauml_defaultFont; metauml_defaultFont:="ec-lmss10"; But this only works for latin modern sans (which I don't like combined with urwgaramond) but not helvetica. I've tried to use some of txfonts and tex-gyre fonts (which use helvetica/heros/nimbus for their sans-serif) by writing metauml_defaultFont:="txss" and metauml_defaultFont:="ec-qhvcb" but I get an error "pdftex (file rtxss): Font rtxss at 600 not found". I've installed the latest context standalone. Is there any other way to use helvetica in metapost/metauml or how to troubleshoot this error? Thanks, matej
