[Therion] Can't change default l_wall style with metapost

[Gilbert (liste)]

Hello,

change your function name to : l_wall_unsurveyed_MYLINE

do not forget the code :


     initsymbol("l_wall_unsurveyed");

     symbol-assign line unsurveyed MYLINE


after enddef; and before endcode;

it will should work.
