Routing Logical Legend

Routing Logical Legend generates a list of all the different components used in a Piping and Instrumentation Diagram. Each component found is mapped to a symbol font from a symbol mapping file. For each component found, an English and a non-English (if provided) explanation is retrieved from the symbol file.

A tabular note is created with as many lines as there are components found, each line displaying the matching symbol font together with the two explanations. This note is placed on the drawing as a legend.
