I think this is one way: \startuseMPgraphic{ARule} draw origin -- (\MPvar{mylength},0) ; \stopuseMPgraphic
\def\ARule#1{% \setupMPvariables[ARule][mylength=#1] \useMPgraphic{ARule} } \starttext Foo \ARule{5mm} bar \ARule{10mm} \stoptext Best regards, Mikael On Thu, Apr 9, 2009 at 8:07 AM, Wei-Wei Guo <wwgu...@gmail.com> wrote: > Dear all, > > I need to use many rules with different lengths.
