Hi,
I'm trying to write a lisp routine to automatically create a thematic map based on polygon topology within my project drawing.
I've got two problems ....
a) My source topology resides within my "project" drawing, therefore I have no attached drawings and any attempts to use the ade_qry functions fail with the message "no drawings are available"
b) I was hoping to use the MAPTHEMTOPO Map command to get round this ... but it doesn't appear to be accessible via lisp. I've tried (command "_MAPTHEMTOPO") and (command "MAPTHEMTOPO") and neither version works.
Can anyone offer any advice please?
Eddie
