material table creation

[cordeiro.cmc]

hello I would like a little complex help the logic would be
I select two layers with different names, and search the entire drawing for lines with that name
after that it creates an execel table with the distances generated from these lines.
and if it is possible for him to do this same command at the same time but with blocks

"with the distances generated from these lines"

Do you mean length ?

Getting length of p/lines for picked layers is easy and make a csv file. 

Did you google say "extract line length to csv Autocad lisp"
