Length of Section In Draft

Hi Everyone,

I was wondering whether there is a way to have an intelligent text which gives the Difference in X, y, or Z values of a section.
e.g. #ZLEN

You could try:

#CUTL

What's the difference between the two? i searched for them in the manuals and it doesnt give an explanation

TCTL Substracts any negative geometry causing the actual cutlength to be less than cutlen.

CUTLEN = end to end
TRUE CUTLEN (TCTL) = end to end minus cuts
DERLEN = Node to node length
