Lisp to dim tons of lines automatically

Hi all....

i need some HELP....i've got the DIM arround 3000+ lines...basically its a road and i need to measure the distance of the natual ground and the distance from the natual ground to the road...its a road with arround 82Km...and i have sections of 25m...there 3000+ sections that i need to DIM...

is there any LIST that can do that automatically by just selecting the lines...

i put a example of what i need to DIM...

i hope some one knows a lisp to help me out....tks
