Thank you, Chris and Greg, for the answers! I tried this:
> object "many_curves" class multigrid > member 0 value "field_0001" > member 1 value "field_0002" > .... and it worked! | I'd suggest using a single field containing all the curves as | polylines rather than a whole lot of fields. It'd be a lot less | overhead. I'll try this next, though it'll take some time to figure out how to write a correct .dx file. (I read the part about polylines in the User's Guide, chap.3, but I still don't know how to express them in a .dx file.) Thanks again, Ryo
