On a mesh we have the ability to move, copy, even multiply contour lines and ridges. We cannot offset them though. Offset would be a very powerful feature for modeling roads.
Also when you select a ridge (line with points that have different heights) you cannot change the elevation of this ridge by a difference in height. When you select a ridge and apply height with the Z command if you apply to all it turns to a contour. Thats not really useful. Archicad should recognize the difference between a ridge and a contour and should give different options in the pet palette.
Z button for contours
dZ button for ridges
Also by drawing a line over a mesh and space click would be nice to have otion to add heights points from single line txt.
Also a command "update Mesh from surveyors data would be nice" so we can put more points on a mesh that has already been edited with lines, polylines and splines.
