Hi, Sorry I allready ask this question in MAP.developer newsgroup but didn't get the right answer so trying there: I'm trying to write a lisp routine to automatically create a thematic map based on polygon topology within my project drawing. Problem, I was hoping to use the MAPTHEMTOPO Map command, but it doesn't appear to be accessible via lisp. I've tried (command "_MAPTHEMTOPO") and (command "MAPTHEMTOPO") and neither version works. All my functions fail with the message "no drawings are available". Can anyone offer any advice please?
