i have two contour lines noting increments of 1m but i want to divide the space between them evenly so that they read as 100mm roughly. I know this isn't accurate but it gives the topographical idea. Offsetting doesnt work because it needs to be evenly divided in 10 parts at the fat and thin areas.

If you don't have a program like Civil 3D you may be out of luck.  You're going to have to draw perpendicular lines between critical areas, divide them into 10 increments, and then fit a spline thru the points.  If all you have are two contours to do this with the manual effort shouldn't take too long.  If you had a full drawing with many contours it would be a nightmare.  But if you need to get the work out I'd attack it this way and look for a better method somewhere on down the line.Dave.

You could use the lisp routine from the below site to generate intermediate contours.I don't believe it has options for multiple intermediate contours though. http://www.jefferypsanders.com/autolisp_Rollin.html

Another option would be to reconstruct the 3D digital terrain model from your contours and then re-create contours (more densely) from the DTM.
