Ok, so in map3d I can use
attach data source
connect data source
define link templates
generate data links
(in that order) to attach data in an excel spreadsheet to a bunch of text objects in my drawing. The spreadsheet is keyed on the text in the text objects.
However - I can't then make a thematic map based on this data! Using the thematic map tool, with either "data" or "sql" expression, acad reports that "No link templates exist". Which seems odd because I already linked the data in using one.
Can anyone solve this problem for me?
