Creating Thematic Maps using AutoLisp

Anonymous

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

Eddie,
Queries will only work if you have an attached drawing - at least in
acmap2000. Open a new drawing, attach all drawings associated with your
project, then run your query.
