shapefile - How can I represent distance using the dashes or markers of a vector line?


I am a very basic user and dont know the lingo to get to the gist of my question so some background might help.


Ive volunteered to create a pre-incident planning system for my rural fire department. Our primary vulnerability are extremely long un-mapped driveways.


So far Ive successfully transferred GPS data of the driveways over aerial photography of the district as bright green lines(a .SHP layer) with a label showing the length of each driveway. It looks great and is very useful as is.


Now the question: I want to draw the driveway vector lines as dashes or with markers set at 100-foot lengths. Our supply-line hoses come in 100-foot lengths; A vector line defined with markers at 100-foot intervals would save me a lot of time and improve the data immeasurably.


So far I have tried "Single Symbol" as a "Simple Line" using a customized dash pattern and the "Marker Line" using the interval placement. Neither of these options maintain the proper length while zooming or "scaling" (if that's the term).


Perhaps it is impossible? (at least at my level of knowledge. I taught myself this far and dont have a lot more time for fooling around :))
